Earth Layers*

Front

What is the Earth's Upper Mantle?

Back

The Upper Mantle is the layer of the Earth located just below the crust, consisting of solid rock that can flow slowly over time.

Front

What is the Earth's Outer Core?

Back

The Outer Core is the layer of the Earth that lies beneath the Mantle and surrounds the Inner Core, composed of liquid iron and nickel.

Front

Where are the Earth's Convection Currents found?

Back

Convection Currents are found in the Mantle, where heat from the Earth's core causes the mantle material to move.

Front

What is the Earth's Inner Core?

Back

The Inner Core is the innermost layer of the Earth, composed of solid iron and nickel, and is extremely hot.

List the layers of the Earth from the outermost to the innermost.

Back

The layers of the Earth from outermost to innermost are: Crust, Mantle, Outer Core, Inner Core.

Front

What is the Crust of the Earth?

Back

The Crust is the outermost layer of the Earth, consisting of solid rock and soil where we live.

Front

What is the Mantle?

Back

The Mantle is the thick layer of the Earth located between the Crust and the Outer Core, made of semi-solid rock.

Front

What is the difference between the Inner Core and Outer Core?

Back

The Inner Core is solid and made of iron and nickel, while the Outer Core is liquid and also composed of iron and nickel.

Front

What role do Convection Currents play in the Earth's Mantle?

Back

Convection Currents in the Mantle help to transfer heat from the Earth's core to the surface, driving plate tectonics.

What is the Lithosphere?

Back

The Lithosphere is the rigid outer layer of the Earth, including the Crust and the uppermost part of the Mantle.
