Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. • Igneous rocks are formed when magma cools in the Earth’s crust, or lava cools on the ground surface or the seabed. WebbDue to the incredibly high temperatures and pressures near the center of the Earth, the outer core is liquid iron and nickel, while the inner core is solid. The motion of the liquid outer core is what gives Earth its magnetic field. Take a look at how temperature in the earth change with depth.
