A: “The answer is rooted in the fact that our planet is a living’ planet, which is still cooling,” said Laurel Goodwin, professor of geology at UW-Madison. She describes the Earth as a series of shells, like a peanut M&M. “The candy shell is the crust, on which we live. The chocolate beneath is the mantle, and the peanut is the core — just imagine that the outer part of the peanut is molten.”
