Convection Currents review

Front

What is the lithosphere of the Earth divided into?

Back

Plates

Front

What happens to heat when convection currents are moving?

Back

Heat rises.

Front

What is the cooling source for convection in the mantle?

Back

The Crust.

Front

What do molecules that are more dense than the surrounding particles do?

Back

Sink down.

Front

What happens to colder, more dense magma near the crust?

Back

It sinks.

Front

What is convection?

Back

The transfer of heat through the movement of fluids.

Front

What role does the mantle play in convection currents?

Back

It is where convection currents occur due to heat from the core.

Front

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

Back

Less dense materials rise, while more dense materials sink.

Front

How does temperature affect the movement of magma?

Back

Hot magma is less dense and rises, while cooler magma is more dense and sinks.

Front

What is the asthenosphere?

Back

A semi-fluid layer beneath the lithosphere that allows tectonic plates to move.
