Ocean Currents TEST Review

Front

What causes an increase in density that results in a deep ocean current?

Back

When warm water loses energy to its surroundings and cools, it increases in density.

Front

Which part of the Earth receives more of the Sun's radiation?

Back

The equator receives more of the Sun's radiation than other parts of Earth.

Front

What type of water does the Gulf Stream carry from the east coast of the United States to the west coast of Europe?

Back

The Gulf Stream carries warm water.

Front

What results from uneven heating of Earth's oceans from the Sun's radiation?

Back

Convection currents result from uneven heating of Earth's oceans.

Front

What three factors most directly affect surface currents in the oceans?

Back

Surface winds, the Coriolis Effect, and continental deflection affect surface currents.

Front

Define ocean currents.

Back

Ocean currents are large-scale movements of water within the oceans, driven by factors such as wind, temperature, and salinity.

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the deflection of moving objects, such as ocean currents, due to the rotation of the Earth.

Front

How do surface winds influence ocean currents?

Back

Surface winds push the water, creating currents that flow in the direction of the wind.

Front

What is upwelling?

Back

Upwelling is the process where deep, cold water rises to the surface, bringing nutrients that support marine life.

Front

Explain the role of temperature in ocean currents.

Back

Temperature affects water density; warmer water is less dense and tends to rise, while cooler water is denser and sinks.
