How deep is the deepest mine in the world? How deep would you have to dig to reach the mantle? Let's pretend that you and your friends tried to dig a hole in your backyard to find a shortcut to China. The thing is, you guys had special suits that could withstand extreme temperatures, so you would not die. If you were somehow able to reach the mantle, what would it look like? What kinds of things would you see? How about the outer core? Inner core? What would it look like as you approached the surface (the crust) on the other side?
1) 3.6 kilometers deep in South Africa
2) 35 kilometers to get to the Mantle
3) I would see a sea of liquid rock near the core. But as I first drilled through the crust I would see rock, not in liquid form. In the outer core I would swim in a sea of Iron. In the inner core i would see, in rock form, Iron again. As I approached the surface again I would see chunks of rocks.
