Water Cycle






In summer, evaporation rate is high.
Water from seas, rivers, lakes ponds evaporates faster and turns into water vapor which rises in the air.
The air above is cool so water vapor cools and changes into tiny drops of water.
These water drops form clouds.
Inside the clouds, the small drops join together and become bigger and heavier.
When they are very heavy, clouds cannot hold them and the water falls to the ground as rain.
This rain water flows back into the ponds, lakes, river and seas
It again evaporates and we get rain.
In this way, this cycle is continuous and is called water cycle.
Ex-D p103: How does the Sun’s heat affect the humidity of a place?
The Sun’s heat leads to the presence of more water vapor in air and thus makes weather humid.
Additional question: What are the seasons in Kashmir? (Write the question and answer in your notebook.
