Answer 1

a. the mantle

according to natgeo, "the mantle is the mostly-solid bulk of earth's interior. the mantle lies between earth's dense, super-heated core and its thin outer layer, the crust. the mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of earth's total volume."
