The layer on Earth with the most mass in the mantle, which is made up of silicate compounds, iron, silicon, magnesium, oxygen and aluminum. The mantle is a solid mass that generates heat reaching over 1,832 degrees Fahrenheit, which causes it to melt in a way similar to plastic.
The Earth's mantle is located directly underneath the Earth's crust, which is the outermost layer. The crust contains the least mass and is the most delicate layer, which makes it prone to damage during earthquakes. The outer core is located on top of the inner core and under the mantle, and it is composed of about 90 percent molten rock and 10 percent sulphur.
