Earth is made up of iron, magnesium, nickel, and rock. The crust is the outer layer, only 5-40 km thick. Is has two parts, oceanic crust and continental crust. Continental is made up of granite, while oceanic is made of basalt.
The mantle is the second layer of the earth. It has three parts to it: lithosphere, mesosphere, and ionosphere. This layer is about 3,000 km thick and is made up of iron and magnesium as well as rock. The mantle has millions of convection currents inside of it, helping form the magnetic field around the Earth's atmosphere.
Finally, there's the core. It has only two parts, called the inner and outer core. They are both made of iron and nickel. The outer core is a liquid layer that covers the solid ball of iron we call the inner core. The inner core is solid because of all the pressure and heat applied to it from the layers above, making it unable to become a liquid layer. Also, the outer core is the only layer that's liquid. The rest are solid.

Why do scientists believe that the earth is made up of different layers?
for the same reason that if you pour oil on top of a jar of water the oil stays on top. the layers of the earth have different densities and so the heaviest stuff sank to the center while the lighter stuff rose to the top.
