Introduction:
What are water bodies?
Water reservoirs, either natural or manmade are known as water bodies. Different names have given to these different bodies according to their size, properties etc. Moving water such as rivers or streams is also considered in the bodies of water.
Numbers of types of water bodies are present in planet earth. About 71% of earth crust is consisting of some form of this universal solvent.
Although there is enormous amount of water is present in different bodies, quite few amounts is present in the form of fresh water and much smaller quantity is in our reach.

Importance of Water Bodies
Water is one of the most important parts of life cycle. Directly or indirectly, it is used by all living things or non living beings but this is not the only use of this universal solvent. In this portion some importance of water and its bodies are discussed.
Source of Oxygen
Everybody knows plant produces oxygen by the process of photosynthesis but the question is: what is the raw material for that process??? The answer is based in the thing which is discussed throughout the discussion, water.
Plants absorb water and convert its oxygen into oxygen gas. You can call it a miracle or a common scientific phenomenon but it works like a never ending cycle that plants convert water into oxygen and that oxygen is again converted in water by respiration or combustion or any other way. In oceans, algae also play this trick.
Climate Control
Water bodies are responsible of the air currents. They are the “Earth Coolers” as they create currents, create winds, causes rains, reflect heat from the sun etc. Without water bodies our earth would be much warmer and difficult place to live for all habitats.
Energy
the problem of gas exchange, as water is not present in all of the terrestrial
During the Earth’s known existence, many raise questions to a substance that is a vital necessity to our life here. Some even may claim that the start of our lives may have occurred and begun in a single drop of this universal solvent. This mysterious compound, which may have led to our development and the survival of our existence what, is it? This is H2O, or as we call it, Water. This vital life form covers over 70 percent of the Earth, and makes up about 70 percent of our body as well. We know all of this though, so what is the history behind the thing that keeps me functioning? I will need to look at: who discovered water, how it received its identity, the discovery of its chemical make-up, and its vitality to us. There is so much left uncovered about this major part of our lives. Many know of water but people don’t know what it is.
How Water Is Related To Chemistry Water is a polar solvent, its molecule is covalently bonded that makes up for an unequal sharing of the electrons resulting in partially positive and partially negative water molecule. Organic molecules like Ethane and many other molecules are non-polar, that is they neither have a positive nor a negative end. As a result, he individual molecules within the water are greatly interconnected because of the presence of weak hydrogen bonds. Water acts as a universal solvent. All the living things are made up of entities, called atoms and molecules, and these entities are inside aqueous solutions that is the solutions containing elements dissolvable in water. Defining solutions, these are homogeneous mixtures of the molecules made up of two or more elements. Usually, the solvent is the substance, which is present in the solution in the largest amount, forming, most of the time a liquid. The substance that is in the lesser amount of the solvent is called solute. Disbanding of an ionically bonded compound, for instance sodium chloride or NaCl by means of water is the easiest process. Nevertheless, looking at their molecular makeup sets up the solubility of a lot of molecules. The biochemical foundation for this process is that the organic breaks up in to compounds called lipids that lack polar covalent bonding in certain regions. Fats are member of the lipids group. The polar water molecule that is covalently bonded behaves so as to keep out non-polar molecules that result in the clumping together of fats. Thus, the make up of a lot of molecules to a great extent affect their solubility. Water has a tendency to break down into H+ and OH- ions. During this disassociation process, the oxygen hold on to t...
How to obtain it, how to store it, how to harness its power and conserve it has motivated human endeavour in a myriad of ways. It has also been the catalyst for the development of significant cultural practices which have generated intangible cultural heritage values. It has inspired poetry, literature, artistic endeavour such as painting, dance and sculpture. It has informed and inspired the development of philosophies and religious practice. The cultural heritage of water, therefore relates not only to the technology and architecture that humankind has developed to manage, utilise and celebrate its life giving properties but also to those intangible values that have shaped our beliefs and
Water is very essential to our bodies as it is a solvent, it is capable to dissolve a lot of different constituents in our bodies, and this is why water is such an effective solvent. It’s also referred as the “universal solvent” because of its capabilities of dissolving more liquids than most of the other liquids. It’s able to dissolve things such as salts, sugars and amino acids will dissolve readily in water. Water is also imperative to all living things because it’s able to transports minerals, and nutrients.
The Sun is the powerhouse of the Earth’s water cycle. During the daylight hours the energy from the Sun heats the air and the surface of the ocean (Bethea, 2011). The energy from the Sun breaks the bonds of the water molecules, which results in liquid molecules of water evaporating from the oceans and water bodies and rising into the atmosphere as
Water is one of the most common substances on the the planet covering over 70% of the Earth 's surface. We ourselves are also made up of mostly water and it 's a trait shared by all other living organisms. It is unusual in that it can exist in 3 different states of matter: solid, liquid and gaseous. At standard ambient temperature and pressure it is a liquid and is almost colourless with little to no smell or taste of it 's own. It has no caloric value nor does it provide any vitamins or minerals. Yet water is an essential nutrient to all organisms. Some have argued that it is the single most important molecule for life on the planet.
The hydrosphere is the area of the Earth, where water movement and storage occur; as liquid water on the surface, such as rivers, lakes, oceans, and beneath the surface such as groundwater, or ice. Water exists in many states, which could be in the form of polar ice caps, and glaciers, and as water vapor in the atmosphere. (Dorsner, 2017).
Even though most do not regularly recognize the important role that water plays in all life, based upon everything that we know about water and its importance to human beings, we can see that fresh and clean water is vital to the very existence of the human race. Water is required for all living things to continue to live, including human beings.
The Biological Importance of Water as a Solvent and as a Medium for Living Organisms
Water is an essential nutrient that our body requires every day. Without water human life cannot be sustained. Water deprivation kills faster than lack of any other nutrient. People do not think of water as a nutrient and don’t realize the important role of water in the body functions.
There is a global shortage of drinking water. A person might wonder how this can be if seventy percent of the earth’s surface is covered by water. Most of the Earth’s water is unsuitable for human consuption. Ocean water is salt water, which makes up 97.5% of all water on the planet. Freshwater is only 3.5% of all the water on Earth. Drinking water is sourced from bodies of freshwater.
Water covers about seventy one percent of Earth’s surface. Earth is the only planet to have stable bodies of liquid water on its surface which is crucial for all known life forms. Water is a substance which acts as a solvent in which organic compounds can mix, and it is the substance which is thought to be necessary to facilitate the formation of life. There are many forms of water which include ice, liquid, and gas. Because water can exist as a gas, it can be stored in the atmosphere and be delivered as precipitate. Water also helps regulate the climat...
Water is our main source of our life. We need it to live, drink, bathe,
According to the U.S. Geological Survey, 60% of human body is composed of water and 70% of the brain is made up of water. Every day, we need to drink about 2.4 liters of water to replace the water lost in our daily activities. We do have enough water on the earth but we don’t have enough freshwater supply. The earth is covered by 70% of water but only 1% of that is freshwate...
