The inner core is the hottest part of the Earth with temperatures up to 5,500°C. It is solid.
The outer core is a liquid layer.
The mantle is made up of semi-molten rock called magma. There are convection currents in the mantle which move, carrying the plates above them.
The crust is the outer layer of the Earth. It is a thin layer between 0-60 km thick. The crust is the solid rock layer upon which we live. It is either continental (found under land masses or continents) or oceanic (found underneath the oceans). The Earth's crust is broken into plates.
