FLASHCARD QUESTION

Front

What are ocean currents?

Back

Ocean currents are large-scale movements of seawater that flow through the world's oceans, driven by factors such as wind, temperature, salinity differences, and the Earth's rotation.

2.

FLASHCARD QUESTION

Front

What are the two main types of ocean currents?

Back

The two main types of ocean currents are Surface Currents and Deep Currents.

3.

FLASHCARD QUESTION

Front

How do ocean currents affect climate?

Back

Ocean currents help regulate the Earth's climate by distributing heat from the equator to the poles, influencing weather patterns and temperatures.

4.

FLASHCARD QUESTION

Front

What is the role of convection currents in the ocean?

Back

Convection currents in the ocean occur when warm water rises and cold water sinks, creating a cycle that helps distribute heat and nutrients throughout the ocean.

5.

FLASHCARD QUESTION

Front

What happens to ocean water at the poles?

Back

Ocean water at the poles becomes extremely cold and salty, causing it to sink due to its higher density.

6.

FLASHCARD QUESTION

Front

How does salinity affect ocean water density?

Back

Higher salinity increases the density of ocean water, causing it to sink, while lower salinity results in less dense water that tends to rise.

7.

FLASHCARD QUESTION

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as ocean currents, caused by the rotation of the Earth, influencing the direction of currents.
