Question
About 71% of the earth’s surface is covered with water, then why do we face scarcity of water?
Solution
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 water droplets come together to form large water droplets.
- The heat of the sun causes the evaporation of water from the surface of the earth, oceans, lakes, rivers, and other water bodies.
- The large water droplets become heavy and the air cannot hold them, therefore, they fall as rain.
- Water vapour is also continuously added to the atmosphere through transpiration from the surface of the leaves of trees.
- Warm air carrying clouds rises up.
- Higher up in the atmosphere, the air is cool.
- These droplets floating in the air along with the dust particles form clouds.
