Earth's Layers

Front

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, consisting of solid rock. It is divided into continental crust (thicker and less dense) and oceanic crust (thinner and denser).

Front

What is the mantle?

Back

The mantle is the layer of the Earth located between the crust and the outer core. It is the thickest layer and is made of semi-solid rock that can flow slowly.

Front

What is the outer core?

Back

The outer core is a liquid layer composed mainly of iron and nickel, located beneath the mantle and above the inner core. It is responsible for Earth's magnetic field.

What is the inner core?

Back

The inner core is the Earth's innermost layer, composed of solid iron and nickel. It is extremely hot and under immense pressure.

Front

Which layer of the Earth is the thickest?

Back

The mantle is the thickest layer of the Earth.

Front

What is the difference between continental and oceanic crust?

Back

Continental crust is thicker and less dense than oceanic crust, which is thinner and denser.

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

Back

Crust, Mantle, Outer Core, Inner Core.

Front

What is the role of the outer core in Earth's geology?

Back

The outer core is responsible for generating Earth's magnetic field due to the movement of liquid iron and nickel.

Front

What is the asthenosphere?

Back

The asthenosphere is a semi-fluid layer of the mantle located beneath the lithosphere, allowing tectonic plates to move.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle.
