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

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 in coastal regions.

3.

FLASHCARD QUESTION

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, causing currents to curve rather than move in a straight line.

4.

FLASHCARD QUESTION

Front

What is the difference between surface currents and deep currents?

Back

Surface currents are driven by wind and occur in the upper layer of the ocean, while deep currents are driven by differences in temperature and salinity and occur deeper in the ocean.

5.

FLASHCARD QUESTION

Front

What causes deep ocean currents?

Back

Deep ocean currents are caused by differences in water density, which is influenced by temperature (thermohaline circulation) and salinity.

6.

FLASHCARD QUESTION

Front

What is thermohaline circulation?

Back

Thermohaline circulation is the global movement of ocean water driven by differences in temperature and salinity, playing a crucial role in regulating climate.

7.

FLASHCARD QUESTION

Front

How do ocean currents impact marine life?

Back

Ocean currents transport nutrients and organisms, influencing the distribution of marine species and ecosystems.
