OCEANS

Reservoir: A storage area usually for water

Hydrosphere: All the waters of Earth combined

Current: Flow of water

SALINITY:

• The amount of salt in water
• The higher the temperature, the higher the salinity
• Water evaporates more quickly in higher temperatures leaving more salt behind.

How is the ocean part of the water cycle?
Most evaporation and precipitation takes place over the oceans.

How is the ocean a resource?
The ocean provides salt for our food, drinking water (after it evaporates), and it is home to many different plants and animals, which are a great food source.
