2. What is water cycle ?
Water never leaves the Earth. It is constantly
being cycled through the atmosphere, ocean,
and land. This process, known as the water
cycle , is driven by energy from the sun. The
water cycle is crucial to the existence of life on
our planet.

5. Evaporation
• Heat energy from the sun causes water in
puddles, streams, rivers, seas or lakes to
change from a liquid to a water vapor.
• This is called evaporation.
• The vapor rises into the air and collects in
clouds.

6. Condensation
• Water vapor collects in clouds. As the
clouds cool the water vapor
condenses into water drops.
• This is called condensation .
• These drops fall to the earth as rain,
snow or hail.

7. Precipitation
• Water falls to the earth from
clouds. Mainly as rain, but
sometimes as snow and hail.
• This is called precipitation .

8. Transpiration
• Transpiration is the process by which
plants lose water out of their leaves.
• Transpiration gives evaporation a bit of a
hand in getting the water vapor back up
into the air.
