What are the four main layers of the Earth?

Back

The four main layers of the Earth are the Crust, Mantle, Outer Core, and Inner Core.

Front

What is the composition of the Inner Core?

Back

The Inner Core is primarily composed of iron and nickel.

Front

What is the Asthenosphere?

Back

The Asthenosphere is a semi-fluid layer of the mantle located beneath the lithosphere, where convection currents occur.

Front

What is the role of convection currents in the Earth's layers?

Back

Convection currents in the mantle help to move tectonic plates.

Front

What is the difference between the Lithosphere and the Asthenosphere?

Back

The Lithosphere is the rigid outer layer of the Earth, while the Asthenosphere is a semi-fluid layer beneath it.

Front

What is the composition of the Outer Core?
