Ocean Currents & Climate

Cold water currents are more likely to be in deep ocean than water water currents because

• ocean tides force cold water downward

• Winds push the cold water down

• cold water has less salt to help it freeze and sink

• cold water is more dense and sinks

Warm water currents affect coastal areas near where they flow by doing what?

• creating greater rainfall along the coast

• creating unusually warm climates for the latitude

The Gulf Stream carries warm water to the North Atlantic Ocean, which contributes

• to a warm water surface current that flows along CA coast

• to a mild climate for the British Isles

• a cold water surface current that flows to the British Isles

• to a harsh winter in the British Isles
