Ocean Currents - Concept Review

Density

• The value for water at 0°C and standard sea-level atmospheric pressure is 1g/cm3

• Relating to the whole world

• A large body of saltwater that covers most of Earth’s surface

• Saltiness or dissolved salt content of a body of water

A large body of saltwater that covers most of Earth’s surface

• Density

Ocean currents

• A directional movement of ocean water; surface currents result from steady winds over the ocean surface; deep currents result from density variations due to temperature and salinity differences

• Density

• Weather

• Migration of animals

Water with a higher density than the water surrounding it would be expected to –

• Mix

• Evaporate

• Rise

• Sink

One of the factors that affects the density of ocean water is -

• Animal behavior

• The seasons

• Gravity

• Salinity

The “underwater rivers” that move through the oceans are called –

• Tsunamis

• Typhoons

• Currents

• Jet streams
