Salinity is the saltiness or dissolved salt content of a body of water. It has been traditional to express salinity not as percent(%), but as parts per thousand(‰). i hope you will like it.
Chemical Oceanography is fundamentally interdisciplinary. The chemistry of the ocean is closely tied to ocean circulation, climate, the plants and animals that live in the ocean, and the exchange of material with the atmosphere, cryosphere, continents, and mantle
Seas and oceans are very huge bodies of saline waters. Their distribution and dynamics are very influential in several ways. Understanding the properties of seawater is inevitable in oceanographic studies. Seawater is one of the most fascinating and plentiful substances on the planet. The basic properties of seawater and their distribution, the interchange of properties between sea and atmosphere or land, the transmission of energy within the sea, and the geochemical laws which are governing the composition of seawater and marine sediments, are the fundamental aspects studied in the subject oceanography.
Lakes are helpful in controlling weather and local climate. Lakes are helpful for creating irrigation facilities and recreation. In some places, lakes are good sources for water supply for drinking. Every lake, is unique in terms of its size, morphometry, water availability, water chemistry, physics, hydrology and biology. There are several type, kinds and categories of lakes in the world.

Studying the geomorphology of lakes is a part of earth science studies. The presence of a lake, in any region, greatly influences the life of the people, living adjacent to it. There are several kinds of lakes in the world. Their characteristics are explained in this module.
seawater is life to many organisms and plants.
it consists of various nutrients which help in the growth and developments of flora and fauna present in the seawater
A nutrient is a chemical that an organism needs to live and grow or a substance used in an organism's metabolism which must be taken in from its environment.
The plankton is divisible into two main groups, the phytoplankton and the zooplankton. The primary productivity which we discussed in chapter 10 is primarily the functional aspect of phytoplankton - the other chlorophyll bearing organisms are also to be included, but in most water bodies such as the culture pond an index of primary productivity could be obtained by the mass or number of phytoplankton in a unit volume of water
The study of physical oceanography helps in understanding all these aspects in detail. Let us see most of these factors and processes in our future modules. Mathematical models of all these processes are also developed using these phenomena and mechanisms. The individual aspects of all the elements of physical oceanography are to be studied in detail.

Salt dissolving in water physical or chemical Def.pdfsinghanubhav1234
Salt dissolving in water physical or chemical Definition Salt water - Salt water or
saltwater may refer to: Saline water, water containing dissolved salts; Brine, water saturated or
nearly saturated with salt; Brackish water, water that is saltier ..... Solubility equilibrium -
Solubility equilibrium is any type of chemical equilibrium relationship between solid and
dissolved states of a compound at saturation. Solubility equilibria involve application of
chemical principles and constants to predict solubility of substances under specific conditions
(because solubility is sensitive to the conditions, while the constants are less so). The substance
that is dissolved can be an organic solid such as sugar or an ionic solid such as table salt. The
main difference is that ionic solids dissociate into constituent ions when they dissolve in water.
Most commonly water is the solvent of interest, although the same basic principles apply with
any solvent. In the case of environmental science studies of water quality, the total concentration
of dissolved solids (not necessarily at saturation) is referred to as total dissolved solids.
Dissolution of an organic solid can be described as an equilibrium between the substance in its
solid and dissolved forms:.... Salt water - Saline water, water containing dissolved salts; Brine,
water saturated or nearly saturated with salt; Brackish water, water that is saltier than fresh
water, but not as salty as ..... Ammonium hydrosulfide - Ammonium hydrosulfide is the
chemical compound with the formula (NH 4)SH. It is the salt derived from the ammonium cation
and the hydrosulfide anion. By passing hydrogen sulfide mixed with a slight excess of ammonia
gives the colourless, micaceous crystals. It dissolves readily in water.. Why is the Ocean Salty?
Geography II series, from TMW Media. All water, even rainwater contains dissolved chemicals
which scientists call \'Salts.\' These salts eventually wash down into rivers and streams and
eventually find their way into oceans and seas.Subjects covered include: The origin of the sea.
The sources of salt. The components of sea water. The salinity of the sea and its variability. How
sea life affects sea waters composition. ... Geography Oceans Water Salt Sediments physical
science TMW Media trailer ... Purifying Salt Peter Procedures for purifying chemicals are being
invented and re-invented all the time. Purification depends very much on the chemicals that are
considered the contamination, and their properties compare to the chemical you are trying to
purify. The mixture that you are trying to purify will dictate how easy the purification process
will be. There are no \'one fit all solutions\', and indeed, some chemicals are so hard to purify that
the finished purified product fetch amazing prices. Purifying Potassium Nitrate (KNO3)
Recrystallization is a physical method targeting the purification of compounds. The procedure

Water (H
2O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart with a hint of blue. It is by far the most studied chemical compound and is described as the "universal solvent" for its ability to dissolve many substances. This allows it to be the "solvent of life". It is the only common substance to exist as a solid, liquid, and gas on Earth's surface.
Soil is the mixture of minerals, organic matter, gases, liquids, and myriad organisms that together support plant life. Two general classes are topsoil and subsoil. Soil is a natural body that exists as part of the pedosphere and which performs four important functions: it is a medium for plant growth; it is a means of water storage, supply and purification; it is a modifier of the atmosphere of Earth; and it is a habitat for organisms all of which modify the soil. Soil is considered to be the "skin of the earth" with interfaces between the lithosphere, hydrosphere, atmosphere of Earth, and biosphere.[2] Soil consists of a solid phase (minerals and organic matter) as well as a porous phase that holds gases and water.[3][4][5] Accordingly, soils are often treated as a three-state system.[6]
This is a great and modified presentation on the topic of life processes.Biology is the science that deals with living things. Sometimes it is necessary to make a difference between organisms that are alive, and other things that are not alive. This might not be as easy as it seems, but in general:
1.Living things react to stimuli.
2.Living things interact with their environment, which includes members of the same and other species.
3.Living things have a metabolism: they take in food which they convert to the energy they need.
4.Living things reproduce: they give birth to others of the same species. This is not true of all individual organisms. In eusocial organisms, some castes cannot reproduce. But, since the sterile workers are all the produce of a single queen, they are one collective.
Many things that appear to be one organism are in fact several living together. An example is lichen. Lichen is a symbiosis between a blue-green alga and a fungus. Organisms that live together may not reproduce together, but their life processes are bound up together. They help each other to live

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
WRI’s brand new “Food Service Playbook for Promoting Sustainable Food Choices” gives food service operators the very latest strategies for creating dining environments that empower consumers to choose sustainable, plant-rich dishes. This research builds off our first guide for food service, now with industry experience and insights from nearly 350 academic trials.

2. What does salinity mean?
Salinity is the saltiness or
dissolved salt content of a body
of water.
It has been traditional to
express salinity not as
percent(%), but as parts per
thousand(‰)
3. Sea water is salty or saline in
taste...
This is because the sea
contains a great variety of salts
and minerals in solution.
These minerals are brought
down down by the rivers in the
silt they carry.
4. Salinity varies from place to
place depending on two main
factors :
1. rate of evaporation.
2. The amount of fresh water
added by rivers and rainfall.
5. DEAD SEA
it has the maximum salinity of
240 per thousand.
ARCTIC OCEAN
it has the lowest salinity of 20
per thousand.
6.
7. Why are Rivers not salty?
River water does not taste salty
since the amount of minerals
present is relatively small. In the
ocean the concentration of salt
increases with continued
evaporation.
