Earth's Layers

Front

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, where we live. It is made up of solid rock and is relatively thin compared to other layers.

Front

What is the mantle?

Back

The mantle is the layer of the Earth located beneath the crust. It is made of semi-solid rock that flows slowly and is much thicker than the crust.

Front

What is the outer core?

Back

The outer core is the layer of the Earth located beneath the mantle. It is made of liquid iron and nickel and is responsible for Earth's magnetic field.

Front

What is the inner core?

Back

The inner core is the innermost layer of the Earth. It is solid and made mostly of iron and nickel, and it is extremely hot.

Front

How does oceanic crust differ from continental crust?

Back

Oceanic crust is denser than continental crust and is primarily made of basalt, while continental crust is thicker and made mostly of granite.

Front

What is basalt?

Back

Basalt is a type of volcanic rock that makes up much of the oceanic crust. It is dark in color and dense.

Front

What is granite?

Back

Granite is a type of rock that makes up much of the continental crust. It is light in color and less dense than basalt.

Front

What is the correct order of Earth's layers from the surface to the center?

Back

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

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, which includes the crust and the upper part of the mantle.

Front

What is the asthenosphere?

Back

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