Question

Explain global water cycle.

Answer 1

Global water cycle :

1. In this cycle, no living organisms are involved.
2. In this cycle, the water evaporates from the oceans, seas, lakes, rivers, etc., due to the heat of the sun and forms clouds in the atmosphere.
3. These clouds are blown over the land by air currents. When they are cool enough, they precipitate the water as rain and snow, etc and some of the rainwater may flow directly into the oceans and rivers while Some of the rainwater and melting snow water seeps into the ground or flows into the rivers and seas.
4. The groundwater comes to the surface again through the pumps used to draw water for irrigation, drinking, and industrial use. The water from the surface of the earth gets evaporated from the oceans, rivers, snow, etc., into the atmosphere.
5. Water vapors are again condensed in the form of clouds and this cycle again restarts.
