Front

What is the lithosphere?

Back

The lithosphere is the outermost, rigid layer of the Earth, made up of the crust and the upper part of the mantle, and is divided into tectonic plates.

What is the mantle primarily composed of?

Back

The mantle is primarily composed of semi-solid rock that flows slowly over time.

Front

What is the difference between the inner core and outer core?

Back

The inner core is solid and composed mainly of iron and nickel, while the outer core is liquid and also composed mainly of iron and nickel.
