Earths Layers

Front

What are the main layers of the Earth?

Back

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

Front

What is the Lithosphere?

Back

The Lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper part of the mantle.

Front

Which layer of the Earth is the least dense?

Back

The Crust is the least dense layer of the Earth.

Front

What is the Mantle made of?

Back

The Mantle is made of semi-solid rock that flows slowly over time.

Front

What is the Outer Core?

Back

The Outer Core is a liquid layer composed mainly of iron and nickel, located beneath the Mantle.

Front

What is the Inner Core?

Back

The Inner Core is a solid sphere made primarily of iron and nickel, located at the center of the Earth.

Front

Why is the Inner Core solid?

Back

The Inner Core is solid because of the immense pressure that exists at the center of the Earth.

Front

What is the difference between the Lithosphere and the Asthenosphere?

Back

The Lithosphere is rigid and includes the crust and upper mantle, while the Asthenosphere is semi-fluid and allows for the movement of tectonic plates.

Front

What are tectonic plates?

Back

Tectonic plates are large pieces of the Earth's lithosphere that move and interact with each other.

Front

What is the role of the Mantle in plate tectonics?

Back

The Mantle's convection currents drive the movement of tectonic plates.
