Front

What are the five layers of the Earth?

Back

The five layers of the Earth are the lithosphere, asthenosphere, mesosphere, outer core, and inner core.

Front

What property is used to divide the layers of the Earth?

Back

Physical properties are used to divide the layers of the Earth.

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.

Front

What is the asthenosphere?

Back

The asthenosphere is the plastic layer of the mantle on which pieces of the lithosphere move.

Front

Which layer of the Earth is easiest to drill through?

Back

The crust is the easiest layer of the Earth to drill through.

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.

Front

What is the mesosphere?

Back

The mesosphere is the layer of the Earth located beneath the asthenosphere and above the outer core.

Front

What is the inner core?

Back

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

Front

What is the main composition of the outer core?

Back

The outer core is primarily composed of liquid iron and nickel.

Front

How does the asthenosphere differ from the lithosphere?

Back

The asthenosphere is semi-fluid and allows for the movement of tectonic plates, while the lithosphere is rigid.
