Test 1.2 Ocean and Seas Practice (2024)

Front

What is the North Atlantic Current?

Back

A major ocean current that flows from the Gulf Stream across the Atlantic Ocean towards Europe, influencing climate and weather patterns.

Front

What is the Alaska Current?

Back

An ocean current that flows southward along the coast of Alaska, part of the North Pacific Ocean currents.

Front

What percentage of all Earth's water is freshwater?

Back

Approximately 3% of Earth's water is freshwater.

Front

What percentage of all Earth's freshwater is in liquid form?

Back

About 0.7% of all Earth's water is freshwater in liquid form.

Front

What current follows the North Atlantic Current?

Back

The Canary Current.

Front

Define ocean currents.

Back

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

Front

What is the significance of the Gulf Stream?

Back

The Gulf Stream is a warm ocean current that originates in the Gulf of Mexico and flows into the Atlantic, significantly affecting the climate of the eastern United States and Western Europe.

Front

Explain the role of ocean currents in climate regulation.

Back

Ocean currents help distribute heat across the planet, influencing weather patterns and climate by transporting warm water from the equator towards the poles and cold water from the poles towards the equator.

Front

What is the difference between surface currents and deep-water currents?

Back

Surface currents are driven primarily by wind and affect the upper layer of the ocean, while deep-water currents are driven by differences in water density and temperature.

Front

What is the importance of the Antarctic Circumpolar Current?

Back

It is the world's largest ocean current, encircling Antarctica and playing a crucial role in regulating global climate and ocean circulation.
