The different layers
There are 4 layers of the earth, the crust, mantle, outer core and the inner core. each of these layers make up the earth.
The crust: The crust of the earth is the this outer layer of the earth and it is where we live. The crust is about 5km thick at the bottom of the ocean and is about 70km thick on land.
The mantle: After the crust is where the mantle is. The mantle is aproximately 2897km thick and takes up about 85% of the earths total mass. It is mostly made out of a thick solid rocky substance, but it has more magnesium and iron.
The outer core: The outer core is mostly made out of iron and nickle. It is very hot, the temperatures can be from 4400 to 5000+ degrees Celsius, because it is so hot the iron and nickle melt, turning into magma.
The inner core: The earths inner core is believed to be completely made out of iron and nickle, its temperature is around 5000 to 6000 degrees celcius. Although the inner core is extremely hot, it isn't liquid, in fact it is actualy a solid metal ball. whys this you may ask?, because in the center of the earth there is so much pressure that it can't melt, unlike the outer core.
