An Overview of Rivers
A river is a stream flowing on the earth. The source of rivers is usually ice glaciers, i.e., glaciers, lakes, natural sources or springs or rainwater. Any river ends in a big ocean, lake or desert. Rivers usually contain fresh water. A river begins at one source (or more often several sources), follows a course and ends at a mouth.

River Current
Information About River
The course through which the river flows is called the river bed and the earth on each side is called the river bank. The movement of water in a river is called current. The current is usually strongest near the source of the river. Rivers can flow down mountains, along valleys or plains, and form canyons or valleys. Some flow throughout the year. Others flow seasonally or during wet years. A river may be only kilometres long, or it may extend over most of a continent.
Benefits of River
The river is that source of water, which is born due to rainwater. The water of the river is always flowing. This flowing water of the river comes out of the mountain or spring and joins many tributaries and merges into the sea.
For Farmers: The farmers get the maximum benefit from the river. Because the freshwater from the river helps in growing the crops which is a great help to the farmers. Therefore, the areas of the fields living near the river are always fertile crops because river water helps farmers in maintaining the water level in the fields.
Electricity Production: River water is also used for the generation of electricity and the flow of the river is stopped by making a dam. After that, electricity is produced from that water. Today's modern world is running with the use of electricity.
Help with Construction Works: The river helps us in many important constructions like strong houses, buildings and many more. Because in such construction works, strong rocks found in the river are used.
We get many benefits from the river, due to which the river is very important for our life.
