Layers of the Earth

Front

What is the Inner Core?

Back

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

Front

What is the Mantle?

Back

The Mantle is the layer of the Earth that makes up about 85% of its total weight and is located between the crust and the core.

Front

What causes the movement in the lower Mantle?

Back

The movement in the lower Mantle is caused by convection currents, which are the result of heat from the core.

Front

What is the composition of the Earth's core?

Back

The Earth's core is mostly made of iron.

Front

What is the hottest part of the Earth?

Back

The hottest part of the Earth is the Inner Core.

Front

What is the Crust?

Back

The Crust is the outermost layer of the Earth, which is solid and relatively thin compared to the other layers.

Front

What is the Outer Core?

Back

The Outer Core is the liquid layer of the Earth's core, located between the Mantle and the Inner Core.

Front

How thick is the Earth's Crust?

Back

The Earth's Crust varies in thickness from about 5 km (oceanic crust) to about 70 km (continental crust).

Front

What is the role of convection currents in the Mantle?

Back

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

Front

What materials make up the Earth's Mantle?

Back

The Earth's Mantle is primarily composed of silicate rocks, rich in magnesium and iron.
