6. During part of the water cycle, the sun heats
up liquid water and changes it to a gas by the
process of evaporation. Water that
evaporates from Earth’s oceans, lakes, rivers,
and moist soil rises up into the atmosphere.

vapor as well.

9. Condensation
Condensation

10. As water (in the form of gas) rises higher in the
atmosphere, it starts to cool and become a liquid
again. This process is called condensation.
When a large amount of water vapor condenses, it
results in the formation of clouds.

11. Precipitation

12. When the water in the clouds gets too
heavy, the water falls back to the earth.
This is called precipitation.

13. Runoff
Runoff

14. When rain falls on the land, some of the water is
absorbed into the ground forming pockets of water
called groundwater. Most groundwater eventually
returns to the ocean. Other precipitation runs
directly into streams or rivers. Water that collects
in rivers, streams, and oceans is called runoff.
