Convection Currents review

Front

Convection currents occur due to...

Back

Differences in temperature and density.

Front

What is the main cause of tectonic plate movement?

Back

Convection currents.

Front

What is the lithosphere of the Earth divided into?

Back

Plates.

Front

Which layer of the Earth is the LEAST DENSE?

Back

Crust.

Front

When molten material is heated in the mantle it becomes...

Back

Less dense.

Front

What is convection?

Back

The transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself.

Front

How do convection currents affect weather?

Back

They help distribute heat in the atmosphere, influencing wind patterns and weather systems.

Front

What role do convection currents play in the mantle?

Back

They drive the movement of tectonic plates.

Front

What is the relationship between temperature and density in convection?

Back

As temperature increases, density decreases, causing warmer fluids to rise and cooler fluids to sink.

Front

What is the asthenosphere?

Back

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