The Earth is made of many different and distinct layers. The deeper layers are composed of heavier materials; they are hotter, denser and under much greater pressure than the outer layers. No matter who you are or where you live in the world, we all belong to planet Earth. The Earth is the third planet from the sun. It takes 365 days for the Earth to rotate (circle) around the sun one time.
In this web quest you will explore the layers of the Earth's interior (inside) and you will discover what each layer is made of.
