1. How deep is the deepest mine in the world?
-TauTona gold mine in South Africa
2. How deep would you have to dig to reach the mantle?
-35 km
3. 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?
-if my friend and i were to dig through the crust to the mantle it would be a layer of rock. the outer core would be liquid and the inner would be solid. if we dug through the mantle and go through the core, and back through the mantle on the other side, as we approach the crust it would be rocky.
