The surface of the Earth is made up of two parts: 28 % land and 72% water.The water part has another term called Hydrosphere, which came from the greek words: Hydor means water and Sphaira meaning sphere. The study of water is called hydrology which deals with oceans, lakes, seas, streams, rivers, springs and etc. that embraces with the word "Water" (in short, LIFE).
Our Earth had been blessed to have a healthy Hydrosphere given by the Almighty God. Water had its subdivisions which includes geological, biological, chemical, and physical subdivisions, that made the hydrosphere.
The Geological part of the hydrosphere refers to the part which we can see the shore and ocean floor it served as the basin of the earth as it holds up the water that circulates endlessly.
The chemical subdivision of the hydrosphere talks about the chemical properties which can be found in the water that can be used to sustain life or rather oftenly present in the water that maintain the balance in the ecosystem.
The Physical part of the hydrosphere speaks for the waves, and movements of water. There is a study called Physical Oceanography that enhances and researches about the benefits of it, an example of that was there were discoveries that the waves and temperature of the water transmits energy, and the discovery that the water penetrates light and sounds.
And the most important part in the hydrosphere subdivision is the Biological subdivision. It concerns for the life that lives underwater.It tells about the interellationship of marine life, their life cycles, and how the marine animals and creatures behave in their own ecosystem. This portion also provides the greatest benefit of hydrosphere to humans, without it we cannot eat fish and other marine products, and also we could not discover that marine life should be cherished and preserved because of its own wonders.
It is at this juncture that hydrosphere has the greatest contribution in our daily life. Farming, industry, and total population needs it for without it, everything turns into a mess.
The abundance of water was negated by the unbalance distribution of rainfall throughout the year. It resulted to excessive runoff, soil erosion and flooding and water scarcity for human consumption and crop production during the dry season.
The creator had intrusted it to us, but because human beings has no satisfaction, we had despised it. Excessive used of chemical in the huge plantations, throwing of garbage in the rivers, illegal fishing in the seas, applications of Mercury in the processing of gold in the mines, all of those activities has negated and jeopardizes our natural sources of water. When it is abundant, people were hardworking distroying it. So time will come we will all suffer the consequences . . . . When we will treasure every drop of it like gold. . . . .
