• mechanical layers of Earth

thick layer made up of iron and magnesium, solid material between Earth's crust and core.

• outer core

• mantle

• inner core

• crust

a extremely hot liquid layer of molten iron and nickel that surrounds the inner core of Earth

• crust

• mantle

• inner core

• outer core

a dense and hot sphere of solid iron and nickel at the center of Earth

• outer core

• inner core

• mantle

• crust

the solid and rocky outer layer of the earth, tectonic plates area

• inner core

• continental crust

• lithosphere

• asthenosphere

the solid, plastic layer of the mantle beneath the lithosphere; made of mantle rock that flows very slowly, which allows tectonic plates to move on top of it

• lithosphere

• asthenosphere

• inner core

• continental crust

the portion of the earth's crust that primarily contains granite, is less dense than oceanic crust, and is 20-50 km thick

• asthenosphere

• oceanic crust

• convection currents

• continental crust
