Topics
My topic is Layers of the Earth. There are 5 layers of the Earth. They are called crust, upper mantle, lower mantle, outer core, and inner core. The center of the earth is 6000 C.The Earths crust is as large as 670 km to the upper mantle,Right now,there is no such known life in the center of the earth,because it is so deep we cant dig for test samples.There is no water in the center of the earth beacuse its 6000 degrees its too hot! The temperature difference between the crust and the core is 5000 C! The largest layer of the earth is the lower mantle,wich is 2885 km long.
