The Water Cycle is the continuous circulation of water involving processes like evaporation, transpiration, condensation, and precipitation.

•

Evaporation: The process of conversion of liquid water into water vapor (gas) due to the heat of the Sun.

•

Transpiration: The process by which plants lose water in the form of vapor through the stomata in their leaves.

•

Condensation: The process where water vapor cools down and changes back into liquid water droplets, leading to the formation of clouds.

•

Precipitation: The falling of water on Earth in the form of rain, snow, or hail.

•

Groundwater: Water that seeps into the ground and occupies the spaces between rocks and soil, accessible via wells and hand-pumps.
