Earth's Layers

Front

What is the mantle?

Back

The mantle is the layer of the Earth located between the crust and the outer core, composed of semi-solid rock that flows slowly over time.

Front

What are the two types of crust?

Back

The two types of crust are Continental Crust (land) and Oceanic Crust (under the oceans).

Front

What is the order of the Earth's layers from the inside to the outside?

Back

The order is: inner core, outer core, mantle, crust.

Front

What is the outer core?

Back

The outer core is a liquid layer of the Earth located beneath the mantle and above the inner core, composed mainly of iron and nickel.

Front

What is the inner core?

Back

The inner core is the solid, innermost layer of the Earth, composed primarily of iron and nickel, and is extremely hot.

Front

What is the crust?

Back

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

Front

What is the asthenosphere?

Back

The asthenosphere is a semi-fluid layer of the mantle that allows tectonic plates to move.

Front

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.

Front

What is the mesosphere?

Back

The mesosphere is the lower part of the mantle, located beneath the asthenosphere, where rocks are more rigid.

Front

What is the significance of the mantle?

Back

The mantle plays a crucial role in tectonic activity and the movement of the Earth's plates.
