|
the water cycle
|
the movement of water in different states through the Earth. The water cycle includes evaporation, condensation, precipitation, and collection.
|
|
solar radiation
|
Energy given off by the Sun. Solar radiation heats the oceans, leading to evaoporation.
|
|
Evaporation
|
When water changes from a liquid to a gas. For example, water in the oceans or streams turns into water vapor.
|
|
Condensation
|
Gas turns into a liquid when matter is cooled.
Water vapor turns into water droplets because the temperature near the clouds is cooler. The water droplets form clouds. |
|
Precipitation
|
Any form of water that falls from the air
|
|
Collection
|
after precipitation falls, the water needs to go back to the ocean. There are a few ways this happens. The most important ones are runoff and groundwater.
|
|
runoff
|
Water that returns to rivers, lakes, and streams by moving over the surface of the Earth. The water does not go into the ground; it only stays above the surface.
|
|
Groundwater
|
Water that goes into the soil and stays underground. Groundwater is different from runoff because runoff stays above the ground and groundwater is found underground.
|
|
Transpiration
|
Evaporation of water from plants back into the atmosphere.
|
|
Infiltration
|
When water that has fallen as precipitation goes into the ground.
|
|
Streamflow
|
The amount of water in rivers and streams.
The water in rivers and streams comes from different sources, but it will eventually flow back into the ocean. |
