प्रश्न
About 71% of the earth’s surface is covered with water, then why do we face scarcity of water?
उत्तर
About 71% of the earth’s surface is covered with water and even then we face scarcity of water.
Reasons:
- 97% of total water is found in seas and oceans, which is salty and not fit for human consumption.
- Only 3% found in the freshwater and that too available in polar ice caps and glaciers.
- Out of 3% freshwater, only 0.3% is available to us as surface water, in lakes, rivers, and swamps.

- The large water droplets become heavy and the air cannot hold them, therefore, they fall as rain.
