Layers of the Earth

Front

What is the Inner Core of the Earth?

Back

The Inner Core is the innermost layer of the Earth, composed mainly of iron and nickel, and is solid due to extremely high pressure.

Front

Why is the Inner Core solid?

Back

The Inner Core is solid because of the high pressure that exists at that depth, despite the extreme heat.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, often used by geologists to study the Earth's layers.

Front

What is the least dense layer of the Earth?

Back

The least dense layer of the Earth is the Crust.

Front

What layer of the Earth is found between the core and the crust?

Back

The layer found between the core and the crust is the Mantle.

Front

What is the thinnest layer of the Earth?

Back

The thinnest layer of the Earth is the Crust.

Front

What materials primarily make up the Earth's Core?

Back

The Earth's Core is primarily made up of iron and nickel.

Front

What is the Mantle?

Back

The Mantle is the layer of the Earth located between the Crust and the Core, composed of semi-solid rock that flows slowly.

Front

How do geologists study the Earth's interior?

Back

Geologists study the Earth's interior using data collected from seismic waves.

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.
