The global conveyor belt is the longest current in the world.

Front

What two factors cause surface currents?

Back

Surface currents are caused by wind and tides.

What effect are rising sea temperatures having on the conveyor belt?

Back

Rising sea temperatures are causing the conveyor belt to seemingly slow down.

Front

Define ocean currents.

Back

Ocean currents are large-scale movements of water within the world's oceans, driven by factors such as wind, temperature, and salinity.

Front

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

Back

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

Front

What role do ocean currents play in climate?

Back

Ocean currents help regulate the Earth's climate by distributing heat from the equator to the poles.

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.

Front

How do ocean currents affect marine life?

Back

Ocean currents transport nutrients and organisms, influencing the distribution and abundance of marine life.
