Convection Currents review

Front

What causes the movement of Earth's tectonic plates?

Back

Convection currents in the mantle.

Front

What is the cooling source for convection in the mantle?

Back

The Crust.

Front

Which layer of the Earth is the least dense?

Back

Crust.

Front

What is the main cause of tectonic plate movement?

Back

Convection currents.

Front

What are convection currents?

Back

Movement of fluid caused by differences in temperature and density.

Front

How do convection currents affect the Earth's crust?

Back

They cause the tectonic plates to move.

Front

What role does the mantle play in convection currents?

Back

The mantle is where convection currents occur, transferring heat from the core to the crust.

Front

What happens to materials in a fluid when they are heated?

Back

They become less dense and rise.

Front

What happens to materials in a fluid when they cool?

Back

They become denser and sink.

Front

What is the relationship between temperature and density in convection currents?

Back

As temperature increases, density decreases; as temperature decreases, density increases.
