Mantle Convection

Front

What is mantle convection?

Back

Mantle convection is the process by which heat from the Earth's interior causes the mantle to flow, creating convection currents that drive plate tectonics.

Front

What causes convection currents in the mantle?

Back

Convection currents in the mantle are caused by the heat from the Earth's core, which creates differences in temperature and density within the mantle.

Front

What happens to materials as they are heated in the mantle?

Back

As materials are heated in the mantle, they become less dense and rise towards the crust.

Front

What happens to materials as they cool in the mantle?

Back

As materials cool in the mantle, they become denser and sink back down towards the core.

Front

What is the relationship between temperature and density in the mantle?

Back

Generally, as temperature increases, density decreases, and vice versa.

Front

What layer of the Earth is primarily affected by mantle convection?

Back

The crust is primarily affected by mantle convection, as the movement of the mantle can lead to tectonic activity.

Front

Which state of matter is most dense?

Back

Solid is the most dense state of matter.

Front

Which state of matter is least dense?

Back

Gas is the least dense state of matter.

Front

What role does the Earth's crust play in mantle convection?

Back

The Earth's crust acts as a barrier that can trap materials in convection currents, affecting their movement.

Front

How does mantle convection affect plate tectonics?

Back

Mantle convection drives the movement of tectonic plates, leading to geological phenomena such as earthquakes and volcanic activity.
