hi,
There is no life on earth without water. Life almost certainly originated in water. From conception to birth, a child is natured in a sac of water (amniotic) fluid) which protects and cushions the foetus against physical harm. The birth of a child is heralded by the “breaking of waters” after a child is fed on breast-milk which is 90% water (Nagin, 2008).
Definition of water
Water in its pure form is a clear, colourless, odourless and tasteless liquid. It can exist in three states of matter, namely solid (ice), liquid and gas (vapour). The chemical formula for water is H20 which is interpreted as 2 hydrogen atoms and oxygen in a ratio 2:1.

It is an important element of commercial and industrial development.
Water is essential for the existence of plant and animal life. Rainfall is responsible for the growth of wild grasses and trees which in turn help protect the earth surface from soil erosion emanating from the effects of wind and rainfall action. Wild grasses are a natural source of animal feed. Grasses are also used for different purposes such as thatching roofs and weaving. Rainfall is also critically important for dry-land crop production; which is as major source of food and commercial crops such as tobacco, cotton and pyrethrum.
Properties of water
Water has unique physical and chemical properties many of them significant in biology. A very small amount of the Earth’s water is contained within biological bodies and manufactured products. The human brain is 85 percent water. Clean and fresh drinking water is essential to human and other life forms. The adult body requires an average 2-3 litre of water a day in order to function properly. This amount is dependent on the level of activity, temperature, humidity and the body’s physical state whether fit or unfit and the presence of disease process. Most of the water is ingested in foods and the rest is taken straight as pure water. Water is a vital solvent in which many of the bodies’ solute dissolves. It plays an important role in metabolism (VEFPSA, 2009).

2560 Words | 11 Pages
Water and the Importance of it for Life on Earth Water is the only substance that exists naturally on Earth in all three physical states of matter which is gas, liquid, and solid. The H2O molecule is a simple inorganic compound that accounts for approximately 55-60% of the body mass of lean adult humans and is found throughout the human body where it occupies most of the volume of many of the body 's fluids, cells, and therefore the tissues formed by such cells. It is also covers about 70% Earth’s…

Water is a vital part of our planet Earth. Without it, the number of negative impacts it can have is unimaginable. The southeastern states in Brazil are one of the many regions of the world affected by drought. Not having enough water for the necessary daily activities has driven people to extremes in order to get the water that they need. Unacceptable water supply has led to issues in the economy, low food supply, starvation of animals, reduced quality of health, loss of life and more. This raises…

Water And Water : An Essential Constituent Of The Life On Earth
1657 Words | 7 Pages
Water is a transparent fluid that makes up the bodies of water on the planet Earth and is a major vital constituent of the life on Earth. Water covers 71% of Earth’s surface, but the amount of freshwater is only 2.5% of this amount of water, and 98.8% of the freshwater is in ice and groundwater. Less than 0.3% of the entire freshwater is comprised within streams, rivers, lakes, and the atmosphere (Gleick, 1993). This scarce fluid has been used for a variety of human uses, such as agriculture, drinking…
