How the Layers Formed As earth formed, it was made of hot molten magma and intense gravity. As rocks melted, denser materials sank to the center of the.

An Overview The Earth is made of 5 main internal layers and one external layer (the atmosphere). This diagram shows the locations and approximate thicknesses.

Crust  This is the thin, rocky layer we think of as Earth’s surface. Its thickness changes from about 50 miles to 3 miles.

10.2 The Earth’s Interior What is below the crust? The crust is the outermost surface of Earth. Oceanic crust lies under the oceans and is thin.

10.2 The crust and the mantle In a simplified view of Earth, the mantle includes everything below the crust and above the core.

10.2 The crust and the mantle The lithosphere includes the crust and a thin part of the mantle. What lies above the lithosphere?

10.2 The crust and mantle The aesthenosphere lies just under the lithosphere and is the outermost part of the lower mantle. The aesthenosphere is a slushy zone of hot rock with a small amount of melted rock.

10.2 The Earth’s Interior Why is the inner core solid? The core is the name for the center of Earth. –The outer core is made mostly of iron, and is so hot the iron is melted. –The inner core is also made mostly of iron, but it is solid.

10.2 The crust and mantle Earth’s magnetic field is created by the motion of liquid iron in Earth’s outer core. Earth’s magnetic field protects the planet from harmful radiation from the Sun.

10.2 Layers of Earth Compare and contrast the details of the different layers of the Earth.
