Crust, Mantle, Outer core, and Inner core.
The crust is like the skin of an apple it's the rocky outer portion of the earth. The crust is thin compared to the other layers the oceans crust is about three to five miles in depth and the continental crust is about twenty five miles in depth . The temperature on the exposed part of the crust is air temperature the deeper portion is around 1,600 Fahrenheit.
The mantle is 1,800 miles in depth . The mantle is made of hot dense the liquid semi solid rock. Eighty five percent of earths mass and weight is the mantle.
The outer core is a liquid layer of composed nickel and iron. This liquid is about 1,400miles thick. The outer core lies above the inner core and below the mantle. The temperature is about 7,280 Fahrenheit.
The inner core is a solid ball of metal made of composed nickel and iron. The inner core is 1,250 km thick. This layer is ,5000 to 6000 degrees Fahrenheit making it the hottest of all earths layers. That cause's the outer core to melt making it magma.
