essay on 'rivers, stream of lifes' on 750 words

Answer 1

 river is a stream of water that flows through a channel in the surface of the ground. The passage where the river flows is called the river bed and the earth on each side is called a river bank. A river begins on high ground or in hills or mountains and flows down from the high ground to the lower ground, because of gravity. A river begins as a small stream, and gets bigger the farther it flows.

The water in a river is called fresh water. It comes from rain or snow and it can usually be drunk safely, unless it has been polluted. The water in a sea cannot be drunk safely because it is salt water. Both people and animals often live near rivers. They need water to survive and, for humans, rivers were once the only means of fast transport.

Answer 2

The melting snow and pouring rain emerge on tops of mountains and hills forming beautiful mountain streams that flow in the high grounds. As the streams power down, with tributaries and groundwater they gain their volume and become a river. As they leave mountains and the high grounds, rivers slow down and begin to meander. Seeking the path of least resistance, through wide valleys. Finally, the river will flow into a lake or ocean.

All the big milestones in the human history have taken place around river banks. The first civilization emerged in the third millennium BC along the Euphrates, Tigris, Nile, and Indus. And later along the Yellow River. Important revolutions happened along rivers and streams of northern England, which therefore have contributed to the early development of the industry. Most large cities in the world are located on or along the river. An interesting fact is that 65% of the water we drink comes from a surrounding river. Finally, another great reason to keep them clean.
