What does the mantle consist of?

Back

The mantle consists of semi-solid rock that flows slowly and is located between the crust and the outer core.

Front

What is the core of the Earth?

Back

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

Front

What is the outer core?

Back

The outer core is a liquid layer of the Earth located beneath the mantle and surrounding the inner core.

Front

What is the inner core?

Back

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

Front

What is the difference between the crust and the mantle?

Back

The crust is the thin, outermost layer of the Earth, while the mantle is a thicker layer beneath the crust that is semi-solid and can flow.

Front

How does density change from the crust to the core?

Back

Density increases as you move from the crust to the core, with the inner core being the densest part of the Earth.

Front

What is the composition of the crust?

Back

The crust is primarily composed of rocks and minerals, including silicates and various types of soil.
