Diurnal, Semidiurnal, Mixed Semidiurnal; Continental Interference. If the Earth were a perfect sphere without large continents, all areas on the planet would experience two equally proportioned high and low tides every lunar day. What are the 2 tides types? Rather, the term is derived from the concept of the tide "springing forth." Spring tides occur twice each lunar month all year long without regard to the season. Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other.

TYPES OF SEDIMENTARY ENVIRONMENTS.ppt
This document describes various sedimentary environments including continental, marine, and transitional environments. Continental environments include fluvial, lacustrine, paludal, glacial, and desert. Marine environments include shallow marine environments like reefs and continental shelves as well as deep marine environments like continental slopes, rises, and abyssal plains. Transitional environments are at the transition between land and sea and include deltas, tidal flats, beaches, barrier islands, and lagoons.
Topography of ocean floors
Seas and Oceans are blue beauties of the planet earth.
Oceans are vast body of saline water occupying the great depressions on the earth. The surface beneath the oceanic waters is characterized by a lot of relief features.
The structure, configuration and relief features of the oceans also vary from each other.On the basis of Bathymetry and other studies, the morphology of Ocean basins contains a lot of relief features. This module highlights many of those features.
Sea level changes
Sea level change can occur through two main processes: isostatic and eustatic. Isostatic changes are local and caused by land height changes, while eustatic changes are global and caused by ocean water volume changes. During ice ages, water is stored in glaciers causing eustatic sea levels to drop; melting then causes levels to rise. Coastlines can emerge from isostatic uplift or submerge through subsidence. Emergent coasts may have raised beaches and cliffs, while rias and fjords form in submerged areas. Sea level changes impact coastal ecosystems and infrastructure through flooding and erosion.
Delta
1. Deltas form where rivers enter bodies of standing water, depositing large amounts of sediment. They are common features where large rivers meet the ocean.
2. Deltas consist of a delta plain, delta front, and prodelta. The delta plain is the subaerial region with distributary channels, the delta front is the shallow underwater region where mouth bars form, and the prodelta is the deepest region where fine sediments settle out.
3. Deltas are classified based on dominant hydrodynamic processes, including river-dominated, tide-dominated, and wave-dominated deltas which have characteristic morphologies and sedimentary structures.
Deltaic Systems
Deltaic systems form where rivers enter standing bodies of water. They include a mixture of fluvial and marine processes. Deltas can be recognized by thick accumulations of terrigenous sediment that interfinger with fluvial deposits inland and marine deposits basinward. As river flow enters standing water, it loses velocity and deposits coarse material in channel-mouth bars, diverting multiple smaller channels that build the delta outward. Estuarine systems form in drowned river valleys during marine transgression or early regression, and are dominated by fluvial and tidal processes on a smaller scale than deltas.
Glaciers and its types
This document provides an overview of glaciers, including their formation, movement, and important terminology. It describes the key parts of a glacier, including the accumulation and ablation zones. The document also discusses different types of glaciers and their varying speeds of movement. Finally, it covers the erosional and depositional landforms created by glaciers, such as moraines, eskers, and drumlins.
Introduction marine geology
Marine geology is the study of the Earth below the oceans and seas. It examines the character and history of ocean floors and coastal areas. Major developments in marine geology include the HMS Challenger expedition in the 1870s which made the first systematic survey of ocean basins, and the Lamont-Doherty Geological Observatory founded in 1948 which advanced techniques like precision depth recording and piston coring. Deep-sea drilling projects from the 1960s-1980s using vessels like the Glomar Challenger confirmed theories of seafloor spreading and plate tectonics through ocean floor sampling and drilling.
Stress in rock
Stress is the internal resistance of a material against an applied load or force. There are different types of stress that rocks can experience, including lithostatic stress from the weight of overlying rocks, and differential stress from tectonic forces like tension, compression, and shearing. Rocks deform in response to stress in different ways depending on factors like pressure, temperature, and composition. At low stresses rocks deform elastically and return to their original shape when unloaded. At higher stresses near the surface, rocks deform brittlely and fracture. Deeper underground, higher temperatures cause ductile deformation where rocks flow plastically. The stress-strain behavior of rocks is important for understanding their mechanical properties and failure under stress

Coastal Landforms
The document discusses various coastal landforms created by erosion and deposition processes along shorelines. It describes landforms such as headlands and bays, cliffs and wave-cut platforms, caves, arches, stacks, and stumps which are formed by coastal erosion. Beaches and spits are landforms created by coastal deposition, with beaches forming in sheltered areas between high and low tide lines, and spits forming as narrow ridges projecting from the coast due to longshore drift depositing materials.
Coastal Geomorphology Landforms Of Wave Erosion & Deposition
This document discusses various coastal landforms and processes.

It then lists and describes specific coastal landforms like headlands, bays, sea cliffs, beaches, bars, spits, tombolos, sand dunes, salt marshes, and more. For each landform, it provides a brief definition and example photo. Coastal erosion processes like abrasion, hydraulic action, corrosion, and attrition are also outlined.
Introduction to Sedimentology and Stratigraphy
This document provides an introduction to sedimentology and stratigraphy. It discusses key concepts such as sedimentology focusing on accumulation under uniform conditions while stratigraphy records changes over time. Sedimentary rocks form through weathering, erosion, transport, deposition, lithification and diagenesis. Scientists study facies, depositional systems, and system tracts to interpret ancient environments. Stratigraphy reflects changes in the balance between space creation and filling in sedimentary basins. Correlating rock units across regions is important for stratigraphic research.
sedimentary environment (fluvial channel)
This document outlines the key aspects of fluvial channels and deposits. It discusses the origin and stages of river development from mountainous sources. The main forms of fluvial channels are straight, anastomosing, braided, and meandering, with braided bars and point bars being the main deposits. Fluvial deposits have economic importance as aquifers, reservoirs, and hosts for minerals like gold. In conclusion, the presentation covered the origin, forms, deposits, and economic value of fluvial systems.

Sedimentary Rocks
This document discusses sedimentary rocks, including their formation, classification, and characteristic textures and structures. Sedimentary rocks form through the lithification of sediments deposited under water. They are classified based on their composition into clastic rocks (formed from fragments of pre-existing rocks), chemical/evaporite rocks (formed by chemical precipitation), and organic rocks (containing organic matter). Key textures include grain size, shape, packing, and fabric. Common structures include stratification, lamination, cross-bedding, graded bedding, and ripple marks, which provide information about depositional environments.

Ch. 14 the ocean floor
Nearly 71% of Earth's surface is covered by the global ocean. The ocean floor can be divided into four main regions: continental margins, ocean basin floors, and mid-ocean ridges. Continental margins are the zones between continents and ocean basins, and include continental shelves and slopes. Ocean basin floors contain features like abyssal plains, seamounts, and deep-ocean trenches. Mid-ocean ridges are underwater mountain ranges found near the centers of ocean basins where new seafloor is formed through seafloor spreading.
New Microsoft PowerPoint Presentation
1. Carbonate sediments originate on land and in the sea in three major settings: continental, transitional between land and sea, and shallow and deep sea.
2. Marine carbonate depositional systems differ from siliciclastic systems in important ways relevant to sequence stratigraphy.
3. Non-marine carbonates form in terrestrial and aquatic environments without marine influence through abiotic and biotic precipitation processes and differ from marine carbonates.
Midoceanic ridges
Mid-ocean ridges are underwater mountain systems formed at divergent tectonic plate boundaries where new oceanic crust is generated. They consist of a chain of mountains linked by a central rift valley and result from mantle upwelling and melting in response to plate spreading. As the buoyant magma rises to the seafloor at the plate boundary, it emerges as lava to form new ocean crust upon cooling.
Ocean sediments
Ocean sediments originate from various sources and accumulate on the ocean floor. The main sources are weathering of continental rocks, volcanic eruptions, biological activity, chemical processes within the ocean crust and seawater, and impacts from extraterrestrial objects. Sediments are classified based on their origin, size, and composition. The most abundant sediment types are terrigenous sediments derived from weathering of land areas, and biogenous sediments composed of the remains of marine organisms.
Isostasy
This document discusses the concept of isostasy, which refers to the equilibrium between the continental and oceanic crust due to gravitational forces. It was first defined in 1889 by American geologist Clarence Dutton. The main points are that the continental crust must be composed of lighter materials than the ocean floor to remain in equilibrium. Also, wherever the continental crust is thinner under the oceans, it extends below the ocean floor to maintain equilibrium. Early evidence for isostasy came from Pierre Bouguer's 1735 expedition to the Andes mountains, where he observed smaller than expected gravitational attraction that indicated compensation of the mountains' mass.
Coastal hazard
This document summarizes various coastal hazards. It categorizes hazards as either rapid-onset (e.g. coastal flooding from storm surge or tsunamis) or slow-onset (e.g. coastal erosion, land subsidence, or saltwater intrusion). Rapid-onset hazards are caused by sudden events like earthquakes generating tsunamis or storms producing storm surge, while slow-onset hazards occur gradually over time from erosion, sinking land, or encroaching seawater. The document also discusses how human activities like dams, seawalls, and jetties can disrupt sediment flows and influence coastal changes. Mitigation measures proposed include protective infrastructure, emergency response improvements, and climate information services.
Hotspots and Mantle plumes
The document provides an overview of mantle plumes and hotspots. It discusses that mantle plumes are columns of hot material rising from deep within the mantle, and hotspots are the surface expression of these plumes seen as volcanic regions. Hotspots have distinct geochemical signatures and are unrelated to tectonic plate boundaries. They can form hotspot tracks as the tectonic plate moves over them, leaving age-progressive volcanic chains. While hotspots were thought to be fixed in the mantle, evidence now suggests they may move slowly relative to each other over geologic timescales. Mantle plumes provide an explanation for various volcanic and tectonic phenomena seen in the interiors of tectonic plates.
Coastal Features
The document describes various coastal landforms and features including estuaries, barrier islands, headlands, arches, stacks, sand dunes, salt marshes, tombolos, and wave-cut platforms. Estuaries are where fresh and salt water mix at the wide part of a river near the sea. Barrier islands are long narrow sandy islands running parallel to the shore. Arches form natural rock formations with passages underneath, and stacks remain after arch collapse. Sand dunes occur along coastal areas and deserts. Salt marshes are transitional areas between land and salty water. Tombolos connect islands to mainland or other islands. Wave-cut platforms are flat areas at the base of sea cliffs caused by wave action

Sedimentary structure
This document discusses sedimentary structures, which are macroscopic features formed during sediment deposition. It classifies sedimentary structures based on their morphology and formation processes. The key types discussed are physical structures like bedding, cross-bedding, and ripple marks formed directly by sedimentation. Chemical structures like nodules and concretions are formed by precipitation. Biogenic structures such as stromatolites and trace fossils provide evidence of ancient life. Studying sedimentary structures can provide insight into depositional environments, paleocurrents, and stratigraphic relationships.
Origin and destruction of ocean floor ppt ; ocean floor :evolution of ocean f...
The document discusses the evolution of ocean floors over time. It begins forming at mid-ocean ridges through sea floor spreading, as new crust is created and the continents diverge. Mature ocean basins develop and widen until beginning to decline due to continued spreading and shrinking. Finally, subduction eliminates most of the ocean crust and continents collide, forming mountain ranges. Sea floor spreading and subduction are the major forces driving the evolution of tectonic plates and the continuous formation and destruction of ocean floors according to the Wilson Cycle.

Easc116 Ch. 6 - Sedimentary Rocks
This document discusses sedimentary rocks and how they provide clues about past environments. Sedimentary rocks form from the compaction and cementation of sediments like weathered minerals, chemical precipitates, and organic remains. Key clues used to interpret depositional environments include sediment size and shape, mineral composition, sedimentary structures like ripples and cross-bedding, fossils, color, geometry of rock units, and cyclical sequences indicating sea level changes. Together these clues can be used to map facies and reconstruct prehistoric landscapes through the principles of uniformitarianism and lateral continuity.
theory of oceanography
The document provides information about tides, including what causes tides, the different types of tides, and tidal cycles. It discusses how the gravitational pull of the moon and sun cause tidal bulges in the oceans that result in high and low tides as the earth rotates through these bulges. Most coastal areas experience semi-diurnal tides with two high and two low tides each day, but some locations have diurnal or mixed tides. Spring tides occur during new and full moons when the sun and moon are aligned to produce higher high tides and lower low tides, while neap tides have a smaller tidal range.
ocean tide ppt pragati.pptx
Tides are caused by the gravitational attraction of the Moon and Sun and the centrifugal force of the Earth's rotation. They occur as long waves in the ocean and cause regular rises and falls in sea level. There are two high tides and two low tides each day for most places, known as semi-diurnal tides. Spring tides with the highest ranges occur when the Sun and Moon are in alignment, while neap tides have lower ranges when they are at right angles. Tides are important for navigation, fishing, power generation and can impact coastal erosion and flooding.

Tides (Coyle)
Tides are caused by the gravitational pull of the moon and sun on the Earth's oceans. This creates bulges of water on opposite sides of the Earth that result in regular rises and falls of sea level called tides. The moon has a stronger influence than the sun due to its closer proximity. Tides are strongest in coastal areas and weakest in the open ocean. There are typically two high tides and two low tides each day, known as semidiurnal tides, though some locations only experience one of each, called diurnal tides.
Tides
Tides are caused by the gravitational forces of the moon and sun interacting with Earth's oceans, which creates two bulges of water that result in two high tides and two low tides each day. The changing positions and distances of the moon and sun relative to Earth cause variations in tide heights and times. Spring tides occur during new and full moons when the sun and moon are aligned, producing the highest tides, while neap tides happen when the sun and moon are at right angles, resulting in lower tides.
Emily and Nicole
Tides are caused by the gravitational pull of the moon and sun on the Earth's oceans. This causes the ocean levels to rise and fall, creating high tides and low tides approximately every 12 hours on opposite sides of the globe. Spring tides occur during a full moon or new moon and have the highest tidal ranges, while neap tides happen midway between spring tides and have the lowest tidal ranges. Different types of tides are caused by the relative positions of the Earth, moon, and sun.
Seminar presentation on Tide , Bsc geology, MA geography
The document summarizes ocean tides. It explains that ocean tides are caused by the gravitational pull of the moon and sun and the rotation of the Earth. This results in the rise and fall of sea levels twice per day. The key factors that influence tides are the gravitational pull of the moon, centrifugal force, and when the moon and sun are in alignment during new and full moons. Tides vary in type depending on their frequency and the position of the Earth and moon. Spring tides occur during alignment and have the highest tide levels, while neap tides have lower levels when the moon and sun pull at right angles.

Tides
The document discusses the causes and patterns of ocean tides. It explains that tides are caused by the gravitational interactions between the Earth, Moon, and Sun. This results in two high tides and two low tides each day, known as semidiurnal tides. Spring tides occur during full moons and new moons when the gravitational forces are strongest, while neap tides occur during quarter moons when the forces are weakest. The Bay of Fundy experiences some of the largest tides in the world, with spring tides reaching over 15 meters high.
Geniushourpowerpoint.pdf
The document discusses tides and provides information about their causes and patterns. Tides are periodic changes in ocean water levels caused by the gravitational pull of the moon and sun. Most places experience two high and two low tides daily (semi-diurnal) but some have only one of each (diurnal). Tides were discovered over 300 years ago by Isaac Newton, who developed the theory that all objects exert gravitational pulls on each other. The document defines and compares spring tides, which occur during full and new moons, and neap tides, which happen during quarter moons and have smaller differences between high and low water levels.

Tides are periodic changes in the water level of oceans, gulfs and bays caused by the gravitational pull of the moon and sun. Most places experience two high tides and two low tides daily, called semi-diurnal tides, though some have only one per day, called diurnal tides. Tides were discovered over 300 years ago by Isaac Newton, who developed the Equilibrium Theory of Tides to explain how every object exerts a gravitational pull on every other object. There are two main types of tides: spring tides, which occur during full and new moons and have more extreme high and low tides, and neap tides, which happen during half moons and have the
Tides by rockredstar
Tides are caused by the gravitational attraction of the moon and sun to the earth. Lunar tides occur every 12.5 hours and cause the two daily high tides and low tides. Solar tides also occur daily but are smaller. Spring tides during a full or new moon produce the highest tides when the sun and moon are aligned. Neap tides during a first or third quarter moon have the lowest tides when the sun and moon are at right angles. Perigean tides occur when a spring tide coincides with the moon's closest orbit to earth. Coastlines typically experience semi-diurnal tides with two high and two low tides each day, while some enclosed basins have
Ji Won, Bianca and Isabella
Tides are caused by the gravitational pull of the Moon and, to a lesser extent, the Sun. The Moon's gravity creates bulges in the Earth's oceans that result in high and low tides about every six hours. There are two types of tides: spring tides, which occur during a full moon or new moon and have the largest difference between high and low tides, and neap tides, which occur when the Sun and Moon are at right angles to each other and have a smaller difference between tides.

There are two types of tides described: spring tides, which occur when the sun and moon are aligned and exert maximum gravitational pull, causing exceptionally high tides; and neap tides, which occur when the sun and moon are at a 90 degree angle, pulling in opposite directions and resulting in very low tides. The document concludes by explaining that tides are caused by the combined gravitational forces of the moon and sun along with the Earth's rotation, and can vary in type and timing in different locations.
Marine hydrodynamics
This document contains information about a 20-lecture course on marine hydrodynamics. It includes the course schedule, student assessment criteria, course overview, and lecture content for the first 3 lectures. Lecture 1 covers course fundamentals and assignments. Lecture 2 discusses tides, what causes them, tidal bulges and classifications. Lecture 3 derives the tide generating potential due to the moon's gravity and expands it using Legendre polynomials.
Ocean motion
1. Waves transfer energy through water in the ocean. Individual water particles move in circles as a wave passes by rather than moving forward with the wave.
2. Key characteristics of waves include the crest (highest point), trough (lowest point), wavelength (distance between crests), and wave height (distance between crest and trough). Wavelength determines wave speed and how deep the wave disturbs the water.
3. As waves approach shore they slow down and steepen, eventually collapsing in breakers where the crest curls over. Tides are caused by gravitational attraction of the Earth, Moon, and Sun, and vary in daily and monthly cycles.

Lab 6: Tides and Coastal processes
Goals:
1. Understand what causes tides.
2. Understand how deep-ocean waves change and break when they reach a coastline.
3. Understand how shoreline transport of sediment occurs and how it is affected by human activities.
Tides
Tides are actually waves that move through the oceans and large lakes. In the oceans, they have periods of several hours and wavelengths of 1000s of kilometers. Depending on the wave period that dominates in different parts of the world, some places have only one high and one low tide a day (diurnal tides), whereas others have two high (about equal to each other) and two low tides (also about equal to each other) known as semidiurnal. A third type is mixed tides with two highs and two lows a day with different heights, (a high high, a low high, a high low and a low low). California, as the rest of the west coast has mixed tides.
The gravitational pull of the Sun and the Moon causes tides on Earth. The gravitational influence of an object is directly related to its mass and its distance from another object. So even though the Sun has much more mass than the Moon, it is over 380 times farther away from the Earth than the Moon. Therefore, our little Moon wins out and has the most influence on the tides on Earth.
As the Earth spins about its axis, centrifugal force keeps water balanced on all sides of the planet. However, the Moon's gravitational forces disrupt this balance by pulling the water towards the Moon. A double "bulge" is formed—one side pulling toward the Moon and the opposite side pulling away from it, just like swinging a water balloon causes it to stretch both toward AND away from your hand. The areas where the bulging occurs experience high tides.
Tides are predictable, but their periods do not coincide with the 24 hour Earth day. The Moon takes about 24 hours and 50 minutes to line up again exactly with the same point on the Earth. Therefore, the timing of the tides shifts almost an hour a day. Because the relative positions of the Sun, Earth and Moon change over the course a day, a month and a year, the absolute heights of diurnal, semidiurnal and mixed tides vary over these periods. For example, even within the same ~25 hour period, the heights of the semidiurnal tides are not exactly the same, although they are close. Even more significant changes are seen over a monthly cycle, with higher-than-normalspring tides (not named for the season but because the water "springs" higher than normal) and the lower-than-normalneap tides.

Ocean tides, types and theories
The document discusses ocean tides and their causes. It explains that tides are caused by the gravitational pull of the moon and sun, which create two tidal bulges on Earth. The timing of tides is related to Earth's rotation and the moon's revolution, resulting in a tidal period of about 24 hours and 50 minutes. Tides can be semidiurnal (two high tides and two low tides per day) or diurnal (one of each per day), depending on coastal geography. Spring tides occur during new and full moons when gravitational forces are strongest, while neap tides happen at quarter moons with weaker forces.
tides_DrSS.pptx
The document summarizes tides and their causes. Tides are the daily rise and fall of sea levels caused by the gravitational pull of the Moon and Earth's rotation. The Moon's closer proximity to Earth means it has a stronger gravitational pull than the Sun. This pull creates tidal bulges in the oceans on the sides facing and facing away from the Moon. As Earth rotates, different locations experience high and low tides passing through these bulges. Spring tides occur during full and new Moons when the Sun and Moon pull together, creating higher tides. Neap tides happen at half Moons when the Sun and Moon pull at right angles, resulting in lower tides.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

- 2. IN SERVICE COURSE, II-SPELL 18-11-2020 to 27-11-2020 Prepared by Arun Kumar PGT(Geography) KV, Aizawl(Mizoram)
- 3. What is a Tide? The periodical rise and fall of the sea level, once or twice a day, mainly due to the attraction of the sun and the moon, is called a tide
- 4. t
- 5. Types of Tides Tides vary in their frequency, direction and movement from place to place and also from time to time. Tides may be grouped into various types based on their frequency of occurrence in one day or 24 hours or based on their height.
- 6. Tides based on Frequency •Semi-diurnal tide : The most common tidal pattern, featuring two high tides and two low tides each day. The successive high or low tides are approximately of the same height. • A semidiurnal pattern is more typical of the East Coast.
- 7. t •Diurnal tide : There is only one high tide and one low tide during each day. The successive high and low tides are approximately of the same height. Some areas, such as the Gulf of Mexico, has only one high and one low tide each day.
- 8. t •Mixed tide : Tides having variations in height are known as mixed tides. These tides generally occur along the west coast of North America and on many islands of the Pacific Ocean.
- 9. Diurnal, Semi-diurnal and Mixed Tides
- 10. Examples of Diurnal, Semi-diurnal and Mixed Tides
- 11. Tides based on the Sun, Moon and the Earth Positions The height of rising water (high tide) varies appreciably depending upon the position of sun and moon with respect to the earth. Spring tides and neap tides come under this category.
- 12. Spring tides The position of both the sun and the moon in relation to the earth has direct bearing on tide height. When the sun, the moon and the earth are in a straight line, the height of the tide will be higher. These are called spring tides and they occur twice a month, one on full moon period and another during new moon period.
- 13. Spring tides and Neap Tides
- 14. Spring Tide and Neap Tide
- 15. Neap tides Normally, there is a seven day interval between the spring tides and neap tides. At this time the sun and moon are at right angles to each other and the forces of the sun and moon tend to counteract one another. The Moon’s attraction, though more than twice as strong as the sun’s, is diminished by the counteracting force of the sun’s gravitational pull.
- 17. Tidal Range During Perigee and Apogee Once in a month, when the moon’s orbit is closest to the earth (perigee), unusually high and low tides occur. During this time the tidal range is greater than normal. Two weeks later, when the moon is farthest from earth (apogee), the moon’s gravitational force is limited and the tidal ranges are less than their average heights.
- 19. Tidal Range During Perihelion and Aphelion •When the earth is closest to the sun (perihelion), around 3rd January each year, tidal ranges are also much greater, with unusually high and unusually low tides. When the earth is farthest from the sun (aphelion), around 4th July each year, tidal ranges are much less than average.
- 20. EBB AND FLOW OR FLOOD The time between the high tide and low tide, when the water level is falling, is called the ebb. The time between the low tide and high tide, when the tide is rising, is called the flow or flood.
- 21. EBB AND FLOW OR FLOOD
- 22. EBB AND FLOW OR FLOOD
- 23. Recapitulation (i) Upward and downward movement of ocean water is known as the : (a) tide (c) wave (b) current (d) none of the above (ii) Spring tides are caused : (a) As result of the moon and the sun pulling the earth gravitationally in the same direction. (b) As result of the moon and the sun pulling the earth gravitationally in the opposite direction. (c) Indention in the coast line. (d) None of the above.
- 24. Recapitulation (iii) The distance between the earth and the moon is minimum when the moon is in : (a) Aphelion (c) Perihelion (b) Perigee (d) Apogee (iv) The earth reaches its perihelion in: (a) October (c) July (b) September (d) January
- 25. Home Work (1) What are the types of tides based on frequency? Explain each of them. (2) What are the types of tides based on Their height or position of sun, moon and the earth? Explain each of them. (3) Distinguish between Spring tide and Neap tide. (4) How are tides related to navigation?
