The document discusses the evolution of multicellular life over different eras, noting that early in the Paleozoic there was diversity of marine life, vertebrates began invading land during the Devonian, and a mass extinction at the end of the Paleozoic affected both land and sea life with 95% of ocean complex life disappearing. During the Mesozoic, dinosaurs increasingly dominated as flowering plants appeared, and in the Cenozoic mammals evolved adaptations to live in various environments on land, in water, and air.

Biosphere - feb 26
The biosphere extends throughout the atmosphere, underground caves, and ocean depths wherever life exists. It includes all microbes, plants, and animals. Biologists study lifeforms in the biosphere and work to protect life on Earth and help humanity. Energy and nutrients move between organisms in ecosystems through complex food webs and simpler food chains.
Eco Pp
Ecosystems can range in size from small to large. They contain biotic factors such as living things like tigers, plants, bacteria, and abiotic non-living things like weather, soil, rocks, sunlight and wind. Temperature affects the density of substances in freshwater environments and impacts how easily animals can travel. An organism is a living thing that can act independently, while a population is a group of the same species in an area. A community contains interacting populations and the abiotic environment they reside in. An ecosystem includes both biotic and abiotic components. The biosphere encompasses all life on Earth and can be divided into regional ecosystems. Evolution is the genetic change in populations over generations, influenced by natural selection
Coastal ocean
The coastal ocean biome is where land meets water and includes coral reefs and mangrove habitats found in tropical waters. Organisms in this biome have adapted to the close proximity of land and water. The climate features average wind speeds of 11.3 mph and salinity of 34 parts per thousand. Primary succession would occur if a volcano erupted near the coast, destroying the existing environment and allowing it to be rebuilt over time through the growth of lichens, plants, and eventually animal populations. Secondary succession would follow if an already established coastal land was destroyed and then rebuilt in the same process.

Ecosystems and biomes keaton huffman
This document discusses different types of ecosystems, including aquatic ecosystems which cover most of the planet and contain a wide variety of life from algae to deep sea creatures, land biomes which are defined by their climate and adapted plants and animals, desert biomes which cover one-fifth of the planet due to low rainfall but still support adapted life, and forest biomes which are the largest and most complex systems containing many interdependent species that vary by climate zone.
Evnironment
This document discusses three environmental topics affecting Hawaii: invasive species, erosion, and pollution. It notes that the non-native rose-ringed parakeet population could explode to over 10,000 birds, eating crops and contaminating fruits. A study shows Hawaii is on pace to lose 100 feet of beach in coming decades, with Maui most at risk. Pollution issues include contaminated groundwater, sediments in coastal waters from runoff, and chemicals at Defense sites, with contaminated soil and groundwater remediation a business opportunity.
The great pacific patch
The Great Pacific Garbage Patch is a massive area of marine plastic pollution located between Hawaii and California. It contains over 1.8 trillion pieces of plastic debris, weighing an estimated 80,000 tons. The patch has accumulated due to ocean currents forming a gyre that circulates the trash. Plastic poses threats to wildlife such as seabirds, fish, sea turtles, and marine mammals that can ingest or become entangled in it. Over time, plastic breaks down into smaller pieces but does not fully degrade. Cleanup efforts are ongoing but the patch remains a serious environmental problem.
Luis Flores project succession
This document discusses ecological succession. It defines primary succession as occurring on new surfaces without soil, like after a volcanic eruption, and secondary succession occurring after a disturbance that removes vegetation but leaves soil intact, like after a clear-cutting. Several abiotic and biotic factors that can influence succession patterns are described, including soil development, moisture retention, light availability, species interactions, temperature, and rainfall. Primary and secondary succession are illustrated through examples of a volcanic eruption and clear-cutting respectively.

Marine biology
The Journal of Marine Biology & Oceanography (JMBO) promotes rigorous research that makes a significant contribution in advancing knowledge for marine sciences. JMBO includes all major themes pertaining to organisms in the ocean or other marine or brackish water bodies.
Marine ecology notes
Introduces Oceanography: oceanic plates, continental shelf, abyssal plain, trenches, hydrothermal vents, black smoke, temperature stratification, water masses and circulation, coriolis effect, el nino, larvae and larval ecology.
Marine Ecology: Physical Limiting Factors
This document provides an overview of marine ecology, including basic concepts, marine habitats, lifestyles, and physical limiting factors. It describes the different zones in marine ecosystems like pelagic and benthic, and lifestyles like planktonic, nektonic, and benthic. It also examines various physical factors that limit marine life, such as light, temperature, salinity, nutrients, gases, depth/pressure, and geography. Finally, it discusses how human activities like pollution, development, and climate change are altering these limiting factors and affecting marine environments.
Biomes
Biomes are large groups of ecosystems that share similar climax communities. There are terrestrial and aquatic biomes. Terrestrial biomes include grasslands, tundra, forests, and deserts. Aquatic biomes include marine ecosystems in oceans and freshwater ecosystems in lakes and rivers. Biomes are defined by their abiotic factors like climate and biotic factors like the types of organisms present.
Aquatic ecosystems freshwater
Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes and ponds, rivers, streams and springs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content. This module explains the characteristics of aquatic ecosystems-freshwater ones.
Species extinction, and Natural Selection
The document discusses five major mass extinction events in Earth's history:
1) The Ordovician mass extinction occurred 440 million years ago and was likely caused by global cooling and reduced sea levels.
2) The Devonian mass extinction 350 million years ago caused the extinction of many tropical marine species and was due to changes in sea level and ocean anoxia.
3) The Permian-Triassic mass extinction 250 million years ago was the largest mass extinction ever and was caused by acid rain following massive volcanic gas release.
4) The Triassic-Jurassic mass extinction 210 million years ago allowed dinosaurs to flourish after other vertebrates went extinct, caused by climate change and rising sea levels from carbon dioxide
Aquatic ecosystem
Aquatic ecosystems include both freshwater ecosystems like ponds and rivers, as well as marine ecosystems like oceans. Freshwater ecosystems contain less salt than marine ecosystems. Pond ecosystems specifically rely on algae as the base of the food chain, supporting organisms from bacteria to fish and frogs. Marine ecosystems cover most of the Earth's surface and contain the majority of the planet's water. They are distinguished from freshwater ecosystems by their higher salt content. Aquatic ecosystems perform important functions like nutrient recycling and provide habitats, and are important for tourism.
Marine ecosystem, complex of living organism in the ocean enviroment
This document provides an overview of marine ecosystems. It discusses the origins of life in the oceans, the geography and physical properties of oceans, ocean currents, and the major types of organisms found in marine ecosystems, including plankton, nekton, benthos, and unique organisms found in deep sea hydrothermal vents that rely on chemosynthesis rather than photosynthesis. The document covers a wide range of topics related to marine biology and oceanography.
Species extinction
This document discusses mass extinction events that have occurred throughout history. It provides details on 5 major extinction events, including their timing in millions of years ago and potential causes such as asteroid impacts, volcanic activity, and climate change. Causes of species extinction are also explored, including climate change, changes in sea levels/currents, asteroids/cosmic radiation, acid rain, disease, invasive species, habitat loss, pollution, and human population growth.
Benthic community
The document discusses energy recycling in deep-sea benthic communities. The benthic zone begins at the shore and extends to the bottom of the sea, characterized by low temperatures, high pressure, and minimal sunlight. Benthic organisms have adapted physiologies like slow growth and late reproduction. Due to the lack of light, benthic organisms rely on dead organic matter from higher in the water column and chemosynthesis by microorganisms to create their own food, recycling nutrients and energy through the food web in the benthic zone.
Ecology ecological succession
Ecological succession is the gradual and continuous change in species composition and community structure over time in an area. It occurs through two main types - primary succession, which establishes communities on new areas like bare rock, and secondary succession, which occurs in previously inhabited areas affected by disturbances. Succession proceeds through stages from pioneer to climax communities as conditions change. Deforestation in the Amazon has led to large-scale land use changes and succession, with many secondary forest bird species colonizing but few displacing original forest birds over time. Roads may facilitate some species invasions but succession appears reversible through forest regrowth.
Populations & water quality
This document discusses the relationship between water quality and populations in an ecosystem. It provides examples of different types of population changes, such as seasonal, short-term, and long-term changes. Water quality can significantly impact populations - for example, acidic water from volcanic activity can make a pond "dead". Algal blooms from excess nutrients like fertilizers entering bodies of water can also negatively impact populations by blocking sunlight and reducing oxygen levels. Salmon runs and sardine migrations are important population events that support other species.
Chapter 1 our environment for class 7
The document discusses the environment and its components. It defines the environment as our basic life support system that provides air, water, food, and land. It then describes the biotic environment as the world of living organisms and the abiotic environment as the non-living elements. It also outlines the key components of the natural environment - the lithosphere, hydrosphere, atmosphere, and biosphere. Finally, it defines an ecosystem as a system formed by the interaction of living organisms with each other and their physical and chemical environment, all linked by the transfer of energy and material.
Diversity & adaptations
Diversity in ecosystems refers to the variety of species living in an area. Saltwater ecosystems have greater diversity than freshwater due to more environments in the oceans. Light levels affect diversity in aquatic ecosystems, with more plants and species in upper zones and less in middle and lower zones further from light. Adaptations help species survive, such as fish having gills to breathe. Organisms in different aquatic habitats require different adaptations to factors like temperature, light, and salinity. Freshwater species may withstand freezing or low oxygen, while estuary species tolerate salt levels and intertidal zone species prevent dehydration or hide from waves and birds. Continental shelf and oceanic zone species find food in darkness. Deep sea creatures survive harsh conditions
Marine ecology
This document discusses marine ecology, which is the scientific study of marine life, habitats, and interactions between organisms and their environment. It examines various topics related to marine ecology including trophic structure, components of ecosystems, biomass, nutritional groups, biotic structure, food chains and webs, symbiosis, competition, predators, adaptations to marine living, chordate origins, reptiles, mammals, animals with shells, and effects of pollution on marine life.
Review question chap6
The document contains a student's responses to review questions about ecology chapters. It defines key terms related to biomes and ecosystems. For question 1, the student describes primary succession as beginning with no organisms on bare surfaces, taking a long time to develop soil, while secondary succession begins with an existing ecosystem's destruction, leaving soil and some organisms. For question 4, the two main factors determining a terrestrial biome are precipitation and temperature. Question 5 notes that height above sea level affects temperature and thus the biome. Question 7 states that the substrate, such as sand, mud, or rock, determines the types of benthic organisms in a shore ecosystem. Question 9 lists three differences between freshwater and marine ecosystems as salinity, movement,
Natural Causes of Extinctions
It is a powerpoint presentation that discusses about the lesson or topic: Natural Causes of Extinctions. It also talks about the definition, characteristics and the concepts about the Natural Causes of Extinctions.
Freshwater inland wetlands
Freshwater inland wetlands can be found in various climates and locations around the globe as long as temperatures are moderate and there is sufficient precipitation. They contain diverse vegetation including mosses, trees, shrubs, grasses and aquatic plants. A variety of animal species inhabit wetlands such as birds, fish, reptiles, amphibians and insects. However, wetlands are increasingly threatened by development which drains and fills these important habitats that store water, filter runoff and provide breeding grounds for wildlife.
Biological benthos presentation by hafez ahmad
This document provides information about benthos. It defines benthos as organisms that live on, in, or near the seabed, such as worms, clams, crabs, and kelp. It then discusses the major types of benthic communities found, including rocky shores, sediment-covered shores, kelp forests, and coral reefs. The document also outlines the major kingdoms and phyla that make up benthic organisms, such as algae, sponges, mollusks, and echinoderms. Finally, it discusses the importance of benthos, noting their roles in primary production, nutrient cycling, and as a major link in the food chain.
Arctic vs Antarctic comparison paper
The document compares changes in seabird phenology occurring in the Arctic and Antarctic regions. Seabird phenology varies based on environmental factors like location and species. In the Arctic, threats include saltwater intrusion due to melting sea ice and lack of understanding of some species' distributions. Population dynamics of some Arctic seabird species fluctuate with sea surface temperature and ice extent. In the Antarctic, changes in prey availability due to sea ice and temperature influence seabird phenology. Differences in the Arctic and Antarctic regions that affect seabirds include the presence of non-flying seabirds in Antarctica and where the birds live and breed.
Biology 2.2
Water molecules are polar due to an uneven distribution of electrons between oxygen and hydrogen atoms. A solution is a mixture of substances that are evenly distributed on a molecular level, while a suspension involves nondissolved materials mixed with water. The pH scale measures the concentration of hydrogen ions in a solution, with acids containing more H+ ions and bases containing less, affecting whether the solution is below or above a pH of 7.
Biology 17.4
Six important topics in macroevolution are: adaptive radiation where a single species evolves into different forms that live in different ways; convergent evolution where unrelated organisms independently evolve similarities when adapting to similar environments; coevolution where two species evolve in response to each other; punctuated equilibrium where long stable periods are interrupted by brief periods of rapid change; extinction; and changes in developmental genes.

Biology 29 1 invertebrate evolution
Radial and bilateral symmetry, cephalization, and the presence of a coelom are important characteristics in invertebrate evolution. Radial symmetry is seen in organisms like sea anemones where body parts repeat around the center, while bilateral symmetry is a single dividing line making two halves in worms and arthropods. Cephalization concentrated sense organs and nerves at the front, allowing more sophisticated responses. A true coelom is a fluid-filled cavity lined with mesoderm tissue, found in more complex phyla.
Earth science 7.1
Glaciers are large masses of ice that originate on land from compacted snow and move due to gravity. During an ice age, large ice sheets form on continents and flow outward, carving U-shaped valleys and depositing unsorted sediment called till. Valley glaciers are smaller glaciers confined to mountain valleys that flow due to plastic deformation and basal sliding between the ice and bedrock.
Earth science 12.2
Fossils provide evidence of past life by preserving the remains or traces of prehistoric organisms. Certain fossils called index fossils are associated with a particular span of geologic time, allowing scientists to date rock layers based on the fossil types present. The principle of fossil succession states that different fossils are found in different rock layers based on the period of time when those organisms were alive.
Earth science 5.2
Soil is formed from weathered rock and organic matter and varies in composition with depth, forming distinct horizons. It consists of minerals, organic matter, water, and air. The type of soil depends on the parent material and climate, with pedalfer soils found in humid regions, pedocal soils in drier areas, and laterite soils in the tropics. However, human activities like agriculture and construction can accelerate erosion and damage soil formation.

Cnidarians are soft-bodied carnivorous animals that have stinging tentacles arranged around their mouths. They have a simple nervous system called a nerve net and use cnidocytes and nematocysts to capture prey and defend themselves. Cnidarians typically have a life cycle that alternates between a sessile polyp stage and a motile medusa stage.
Biology 4 2
An ecosystem is shaped by biotic factors like organisms and abiotic factors like climate. Habitats provide the area where organisms live and are defined by biotic and abiotic conditions. Niches describe how organisms use available resources and conditions. Ecological interactions like competition, predation, and symbiosis also influence ecosystems. Ecological succession is the process of communities changing over time after a disturbance.
Earth science 21.3
The greenhouse effect refers to the heating of the Earth's surface and atmosphere from solar radiation being absorbed and re-emitted by greenhouse gases like water vapor and carbon dioxide. Global warming is the increase in average temperatures due to increased carbon dioxide levels from human activities. Changes in ocean circulation, Earth's land and water distribution, and its orbital and axial motions can cause both long-term climate changes and short-term climate fluctuations.

A view of the earth’s past
This document provides an overview of geologic history from the Precambrian era to present day. It describes the major eras, periods, events, climate changes, organisms, and theories of evolution that are recorded in the layers of rock and fossil records. The document is organized chronologically, with each era and period summarized in terms of dominant life forms, environmental conditions, and significant developments or extinctions. Major theories like plate tectonics and mass extinction events are also outlined.
The Paleozoic Era
The Paleozoic Era lasted from 543 to 248 million years ago. It was divided into seven periods: Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, and Permian. Major events included the diversification of multi-celled animal life in the Cambrian and a mass extinction at the end of the Paleozoic that wiped out 90% of marine species. Life colonized land during this era, with plants, fungi and insects moving ashore.
SRJ-earthday-mass extinction.pptx
The document discusses 5 major mass extinctions that have occurred in Earth's history. Mass extinctions refer to the extinction of a large number of species within a short period of time across the globe. The biggest mass extinction was the Permian-Triassic extinction about 252 million years ago, which killed off around 95% of all species. Causes of mass extinctions included climate change, asteroid impacts, volcanic eruptions, and changes in sea levels. The 6th mass extinction is currently underway due to human activity such as pollution, habitat destruction, and overexploitation of resources. Up to 50% of all species may go extinct by 2100 if human impacts are not addressed.

One of the oldest known human bones is Lucy, an Australopithecus afarensis fossil from 3.2 million years ago.
geologic time scale_gen bio 2.pptx
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective[1] is to precisely define global chronostratigraphic units of the International Chronostratigraphic Chart (ICC)[2] that are used to define divisions of geologic time. The chronostratigraphic divisions are in turn used to define geochronologic units.[2]
While some regional terms are still in use,[3] the table of geologic time presented in this article conforms to the nomenclature, ages, and color codes set forth by the ICS as this is the standard, reference global geologic time scale – the International Geological Time Scale.[1][
Cenozoic era
The Cenozoic Era began 65 million years ago after the extinction of the dinosaurs. During this era, mammals diversified and grew larger to fill ecological niches as the dominant land animals. Birds also flourished. The era is divided into periods and epochs where species evolved or went extinct based on environmental changes. During the Paleogene period after dinosaurs, mammals and birds were small but evolved into ancestors of modern groups. In the Neogene, grasslands expanded and large mammals like horses and rhinos evolved. The Pleistocene ice ages drove many large mammals like mammoths and saber-toothed cats to extinction. The current Holocene epoch since the last ice age has seen human impacts drive further extinctions.
cenozoic era- eVERYTHING ABOUT THE TIME OF MAMMALS
The Cenozoic Era began 65 million years ago after the KT extinction event wiped out the dinosaurs. It is divided into periods and epochs, and is known as the "Age of Mammals" as mammals diversified and grew to fill ecological niches previously occupied by dinosaurs. During the Cenozoic, flowering plants flourished, grasses evolved, and climate changes drove evolution and extinction events, with mammals like whales, elephants and horses emerging. Birds also thrived while reptiles like crocodiles persisted from earlier eras. The Holocene epoch marks the rise of human civilization and a new extinction event caused by human impacts.

Biology 26.2
Sponges contain specialized cells like choanocytes that use flagella to move water through the sponge for feeding, respiration, circulation, and excretion. They have structures like spicules made of calcium carbonate or silica that form their skeleton, and archaeocytes that produce these spicules. Sponges reproduce through internal fertilization and larval stages, and some can form protective gemmules during unfavorable conditions.
Biology 22.5
Angiosperms are flowering plants that reproduce sexually through flowers. Flowers contain ovaries that surround and protect seeds. Angiosperms are divided into monocots and dicots based on whether their seeds have one cotyledon (monocot) or two cotyledons (dicot). Flowering plants can also be annuals, biennials, or perennials depending on whether their life cycle is one, two, or more than two years.
Earth science 13.1
The document discusses Precambrian time from 4.56 billion years ago until the Cambrian period over 4 billion years later. It describes shields as flat expanses of ancient metamorphic rock within continental interiors. Stromatolites are layered mounds formed from algae trapping sediment and calcium carbonate. Earth's original atmosphere lacked oxygen but primitive organisms evolved photosynthesis which began releasing oxygen into the atmosphere around 2.5 billion years ago.
Earth science 13.4
The Cenozoic Era saw the rise of mammals as the dominant land animal, replacing reptiles. Flowering plants known as angiosperms also became the dominant land plant over gymnosperms. Major geological events like mountain building, volcanism, and earthquakes occurred in western regions due to plate tectonics during this era. Mammals were better adapted than reptiles for more active lifestyles through bearing live young and maintaining steady body temperatures.
Earth science 13.2
The Paleozoic Era saw an explosion of life, as the continents of Gondwana and Laurasia formed most of the southern and northern portions of the supercontinent Pangea. During the Cambrian, Ordovician, and Silurian periods, life was restricted to the seas surrounding Gondwana, which contained the continents of present-day South America, Africa, Australia, Antarctica, and parts of Asia. By the end of the Paleozoic Era, around 400 million years ago, all continents had fused into the single landmass of Pangea, and plants first began moving from waterside habitats onto land.
Earth science 13.3
The Mesozoic era was the Age of Reptiles, where reptiles like dinosaurs quickly became the dominant land animals due to developing shelled eggs. Gymnosperms also dominated as the prominent plant during this time. A major geological event was the breakup of the supercontinent Pangea. Many reptile groups went extinct at the end of the Mesozoic era.
Earth science 9.1
Continental drift is the hypothesis that the continents were once joined together and have since drifted apart. Originally proposed by Wegener, it suggests the continents were part of a supercontinent called Pangaea approximately 200 million years ago that has since broken apart, moving the landmasses into their current positions. Fossil and rock evidence support this idea, including matching fossil organisms and mountain ranges found on separate continents today that indicate the continents were once joined.
Earth science 8.2
This document discusses seismograms and the different types of seismic waves that are recorded, including P waves, S waves, and surface waves. It explains that seismograms amplify and electronically record ground motion from earthquakes, allowing scientists to determine the epicenter location using travel time graphs from multiple seismographs. The document also covers historical intensity and magnitude scales used to describe earthquake size and introduces moment magnitude as the most widely used scale today because it estimates the energy released.
Biology 28 2 groups of arthropods
This document defines and describes key anatomical terms used to classify groups of arthropods. It discusses the cephalothorax, thorax, and abdomen found in crustaceans, as well as specific structures like the carapace, mandibles, chelipeds, swimmerets, chelicerae, pedipalps, and spinnerets. It concludes with three key concepts: arthropods are classified by body segments and appendages, especially mouthparts; crustaceans typically have two antennae, two or three body sections, and mandibles; and chelicerates have chelicerae mouthparts and two body sections, with nearly all having four pairs of walking legs.
Biology 2.4
Chemical reactions involve reactants being converted into products through breaking and forming chemical bonds, requiring a minimum amount of energy called the activation energy. Catalysts like enzymes speed up reactions by lowering this activation energy, with enzymes being protein catalysts that facilitate substrate reactions within cells.
Earth science 12.3
This document discusses radiometric dating and how it is used to determine the absolute ages of rocks and minerals. It explains key concepts such as radioactivity, half-life, and how comparing ratios of radioactive isotopes like carbon-14 and carbon-12 can be used to calculate radiocarbon dates for samples. Radiometric dating relies on the fact that radioactive isotopes decay at a constant rate and comparing the amounts of parent and daughter isotopes allows the age of a sample to be estimated.

Wind shapes landscapes through processes like deflation, desert pavement formation, and loess and dune deposition. Deflation is the lifting and removal of loose material by wind. Desert pavement is a layer of coarse pebbles created when wind removes finer material. Loess deposits are windblown silt deposits that form blanket-like layers, while dunes are ridges of wind-deposited sand that can vary in shape depending on wind and vegetation factors.
Earth science 7.2
Much of the weathered debris in deserts comes from mechanical weathering like alluvial fans formed where stream slopes abruptly decrease. While chemical weathering is less common, over long periods clays and thin soils can form. Desert streams are ephemeral, only flowing after rain, and often drying up before reaching oceans due to evaporation and soil infiltration. Most desert erosion comes from running water, though wind also erodes deserts, water does the most erosional work.
Earth science 6.3
Groundwater exists below the surface in the saturated zone where all spaces between rock and sediment are filled with water. The water table marks the top of this zone, and groundwater moves slowly through porous and permeable materials. Springs form where the water table intersects the surface, and overuse or contamination can threaten groundwater supplies in some areas. Karst regions have irregular terrain with sinkholes caused by erosion of soluble rock by groundwater in caverns below the water table.
Earth science 6.2
This document defines key terms related to streams and their processes, including bed load, capacity, alluvium, delta, natural levee, floodplain, flood, drainage basin, divide. It also describes concepts such as how streams erode and deposit sediment according to flow velocities, and how flooding occurs and can be mitigated. The overall work of streams is to shape the landscape through erosion, transportation, and deposition of sediment within drainage basins.
Earth science 6.1
The document discusses key concepts about running water and the water cycle. It defines terms like infiltration, transpiration, gradient, stream channel, discharge, tributary, base level, and meander. It explains that water constantly circulates among the oceans, atmosphere, geosphere, and biosphere in the water cycle. Balance in the cycle means annual precipitation equals evaporation globally. A stream's ability to erode and transport materials depends on its velocity, while gradient decreases and discharge increases from headwaters to the mouth.
Earth science 5.1
Mechanical weathering breaks rock into smaller pieces through physical processes like frost wedging, which uses expanding freezing water to break cracks and crevices in rock. Talus is the accumulation of rock debris at the base of cliffs. Exfoliation causes outer rock layers to break off in sheets due to reduced pressure. Chemical weathering alters the internal mineral structure of rock through added or removed elements without changing its composition. Frost wedging, unloading, and biological activity are important natural causes of mechanical weathering, while climate and rock characteristics impact the rate of chemical weathering.
Earth science 12.4
The geologic time scale divides Earth's history into units of time called eons, eras, periods, and epochs. Eons are the largest unit of time and are divided into shorter eras, which are further divided into periods and epochs to create smaller and more specific time spans. These divisions make up the geologic time scale and represent changes in life forms and rock formations over the planet's 4.56 billion year history.

The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).
Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
