100

The current that keeps Western Europe warmer than expected.

What is the Gulf Stream?

100

These winds blow from east to west near the equator.

What are trade winds?

100

This weather phenomenon occurs when trade winds weaken.

What is El Niño?

100

This term describes the vertical rise of deep, nutrient-rich water.

What is upwelling?

200

Tides that occur during the full or new moon

What are spring tides?

200

Currents caused by differences in temperature and salinity

What are deep ocean currents?

200

Winds blowing from west to east between 30° and 60° latitude.

What are westerlies?

200

Upwelling along this coast is suppressed during El Niño.

What is the west coast of South America?

200

The circular movement of water caused by wind and the Coriolis effect.

What is a gyre?

300

The type of tide with one high and one low tide per day

What is a diurnal tide?

300

This massive circular system moves currents around ocean basins

What is a gyre?

300

The force that causes wind direction to curve due to Earth's rotation.

What is the Coriolis effect?

300

El Niño brings droughts to this island-continent.

What is Australia?

300

The apparent deflection of moving fluids on Earth.

What is the Coriolis effect?

400

These polar winds blow from east to west near the poles.

What are polar easterlies?

400

The opposite phase of El Niño.

What is La Niña?

400

This term describes currents driven by temperature and salinity.

What is thermohaline circulation?

500

These tides occur when the Sun and Moon are at right angles

What are neap tides?

500

This type of ocean current forms when surface water is blown away and deep water rises to replace it

What is an upwelling current?

500

The process by which heat moves through fluid, driving winds.

What is convection?

500

This South American country is severely affected by El Niño flooding.

What is Peru?

500

This zone in the ocean marks a rapid decrease in temperature with depth.

What is the thermocline?
