Crust Made up of 1% of the earth Made up of the continents and ocean basins km thick (continents)/ 5-10 km thick (ocean basins) 32 degrees Fahrenheit Made of lower density rocks composed of oxygen and silicon Weakest layer Like the skin on an apple

Mantle Separated into the upper and lower mantle Where most of the internal heat of the earth is located About 2900 km thick 1832 degrees Fahrenheit Consists of rocks composed of elements oxygen, silicon, and magnesium.

Outer Core Made up of liquid composed of iron, nickel, and minor sulfur Very dense/heaviest part of earth 6692 degrees Fahrenheit

Inner Core Solid Composed mainly of iron 7772 degrees Fahrenheit Temperatures and pressures so great that the metals are squeezed together and are not able to move.
