The inner core is made up of heavier materials and is almost two-thousand kilometers thick.The outer core is extremely hot, and its metals are molten. The inner core protects the earth's magnetic field. The outer crust is composed of layers, and is the thickest layer of the earth. The temperature ranges from a thousand degrees C near the crust to over three thousand degrees C near the core. In addition to the outer and inner core, the mantle is also very thick, weighing between one and three thousand pounds. Its main ingredients are magnesium, silicon, and iron.The mantle is the highest point on Earth and contains a solid rock. It is very hot and can be molded like play-dough.
