The Earth has a crust, mantle, outer core and the inner core with each one getting hotter than the next. How come, over millions and millions of years, the heat that is at the center of the Earth hasn't conducted throughout the planet's material so that the entire planet is one even temperature?
This always bothered me because we all learn that temperature diffuses from high areas to low areas, yet the Earth's center is super hot while if you dig a one foot hole, the ground feels quite cold.

<span>The answer is letter C.
Plates move in different directions because the magma moves in “cells” which circulate in different directions. The intense heat of the Earth’s core causes molten rock in the mantle layer to move in a pattern called convection cell. When this occurs warm material rises, cools, and eventually sinks down, as this happens, it is again warmed and it rises again.
Plates help themselves move instead of just surfing along the mantle because of giant convection cells that change the structure of rocks through heat.<span>
