The Crust
The crust is the outside layer of the Earth and is also the thinnest layer. There are two kinds of crust: continental crust and oceanic crust. Continental crust makes up the lands of the continents. Oceanic crust lies below most of the ocean floor. Continental crust and oceanic crust meet underwater.
The Mantle and Core
The mantle is below the crust and is the thickest layer of Earth. The top of the mantle is made of partially melted rock. The crust and the top of the mantle make up the lithosphere, which covers Earth like a thin shell.The deeper part of the mantle is made of solid rock and is under very high pressure with temperatures ranging from 900°C to 2,200°C. Slow convection currents move the rock in the mantle. Cooler rock flows down and hotter rock flows up.The core is at the center of Earth and is made mostly of iron, with temperatures about 5,000°C. The inner core is solid and the outer core is liquid. This liquid moves in currents, which make Earth’s magnetic field.
