Currents and Water Cycle Review

Front

What are ocean currents?

Back

Ocean currents are large-scale movements of water within the oceans, driven by factors such as wind, the Earth's rotation, and differences in water density.

Front

How do warm ocean currents affect nearby land temperatures?

Back

Warm ocean currents raise the temperatures of nearby coastal cities, making them warmer.

Front

How do cold ocean currents affect nearby land temperatures?

Back

Cold ocean currents lower the temperatures of nearby coastal cities, making them cooler.

Front

What causes ocean currents?

Back

Ocean currents are caused by winds, the Earth's rotation, and differences in water density.

Front

What powers the water cycle?

Back

The water cycle is powered by the sun's energy, which drives processes like evaporation and precipitation.

Front

What is the direction of surface currents?

Back

Surface currents move horizontally across the ocean's surface.

Front

What is the direction of deep ocean currents?

Back

Deep ocean currents move vertically, often driven by differences in water temperature and salinity.

Front

What is evaporation in the water cycle?

Back

Evaporation is the process where water changes from liquid to vapor, usually due to heat from the sun.

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation in the water cycle?

Back

Precipitation is any form of water, such as rain or snow, that falls from the atmosphere to the Earth's surface.
