  • Our topic for today is Water Cycle.

  • The Sun heats up the water from oceans, lakes and rivers and water changes into water vapor by the process of evaporation.

  • Plants also lose water in the form of water vapor from their leaves into the air by the process of transpiration.

  • As the water vapor rises up into the air, it starts cooling down and forms tiny water droplets.

  • These water droplets come together to form clouds.

  • This process is called condensation.

  • When the clouds start getting heavy and cannot hold the water droplets anymore, they fall back to the earth in the form of rain, hail or snow.

  • This process is called precipitation.

  • Some of the water that falls on the earth seeps into the ground.

  • This water is available to us in the form of groundwater.

  • The remaining water falls back into oceans, lakes, rivers and seas.

  • This process is called collection.

  • Then, the sun starts heating up this water once again.

  • This circulation of water is called water cycle.

Our topic for today is Water Cycle.
