1. The Water Cycle
The Water Cycle is the movement of water between the atmosphere, land, oceans, and living things
Energy from the sun drives the water cycle

2. Absorbing energy
Water absorbs energy from its surroundings when it heats up
When the water absorbs energy, the molecules begin to move faster
Melting (S to L)
Evaporation (L to G)
Sublimation (S to G)

3. Releasing energy
When water cools down, it releases energy to its surroundings
Molecules slow down
Condensation (G to L)
Freezing (L to S)
Deposition (G to S)

4. Changes of State (S & L)
Melting: solid to liquid
Freezing: liquid to solid

5. Changes of State (L & G) Evaporation: liquid to gas
Condensation: gas to liquid

6. Changes of State (S & G) Sublimation: solid to gas
Deposition: gas to solid

7. Plants and the Water Cycle
Transpiration: evaporation of water from plants
Absorption: plants take
in water through their roots
Capillary Action
Photosynthesis

8. Water Cycle Processes
Runoff: when water flows downhill on Earth’s surface
Infiltration: water on land seeps into the ground and becomes groundwater
Excretion: animals eliminate water
