Ocean and Atmosphere Flashcard

Front

What causes the Sun's light energy to be unevenly distributed across Earth's surface?

Back

The angle of the Sun's rays affects how much energy reaches different parts of the Earth, leading to uneven heating.

Front

What role do ocean gyres play in the Earth's climate?

Back

Ocean gyres help maintain the Earth's heat balance by redistributing heat across the oceans.

Front

Which gyre is situated in the South Atlantic Ocean?

Back

The South Atlantic Gyre is located in the South Atlantic Ocean.

Front

In which direction are ocean currents deflected in the Northern Hemisphere?

Back

Ocean currents are deflected clockwise in the Northern Hemisphere due to the Coriolis effect.

Front

Why are ocean currents important?

Back

Ocean currents are crucial because they move and mix ocean waters, influencing climate and marine ecosystems.

Front

Define ocean gyres.

Back

Ocean gyres are large systems of circulating ocean currents, primarily driven by wind patterns and the Coriolis effect.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as air and water, caused by the rotation of the Earth.

Front

How do ocean currents affect weather patterns?

Back

Ocean currents can influence weather patterns by transporting warm or cold water, which affects air temperatures and precipitation.

Front

What is the difference between surface currents and deep ocean currents?

Back

Surface currents are driven by wind and affect the upper layer of the ocean, while deep ocean currents are driven by density differences due to temperature and salinity.

Front

What is the significance of the Gulf Stream?

Back

The Gulf Stream is a major ocean current that transports warm water from the Gulf of Mexico to the North Atlantic, influencing climate in Europe.
