Currents and Climate

CURRENTS AND CLIMATE: SURFACE CURRENTS &CLIMATE

Warmer climates in coastal areas that would otherwise be much cooler may be created by

• cold-water currents.

• warm-water currents.

• deep currents.

• breaking currents.

Where does the Gulf Stream get its warmth?

• from the Tropics

• from the North Atlantic

• from the British Isles

• from Newfoundland

The Gulf Stream carries warm water from the Tropics to

• the South Atlantic Ocean

• the South Pacific Ocean.

• the North Atlantic Ocean.

• the North Pacific Ocean.

Currents that can keep coastal regions cooler than the inland climate year-round are

• cold-water currents.

• warm-water currents.

• deep currents.

• breaking currents.

The California Current carries cold water to Mexico from

• the South Atlantic Ocean

• the South Pacific Ocean

• the North Atlantic Ocean

• the North Pacific Ocean

Cold, nutrient-rich water from the deep ocean rises to the surface and replaces warm surface water in a process called

• the Coriolis effect.

• upwelling.

• El Niño.

• La Niña.

When upwelling takes place, cold water from the deep ocean

• moves further out to sea.

• causes photosynthesis.

• rises to the surface.

• gets replaced by warm water.

In what ocean do El Niño and La Niña form?

• Indian Ocean

• Atlantic Ocean

• Pacific Ocean

• Gulf of Mexico

What is El Niño?

• A change in water temperature of the Pacific Ocean that produces a warm current.

• A change in water temperature of the Pacific Ocean that produces a cold current.

• A change in the eastern Pacific Ocean in which surface-water temperature becomes unusually cool.

• A change in the eastern Pacific Ocean in which surface-water temperature becomes unusually warm.

What is La Niña?

• A change in water temperature of the Pacific Ocean that produces a warm current.

• A change in water temperature of the Pacific Ocean that produces a cold current.

• A change in the eastern Pacific Ocean in which surface-water temperature becomes unusually cool.

• A change in the eastern Pacific Ocean in which surface-water temperature becomes unusually warm.
