Answer 1

The atmosphere is sort of thick. There’s a dozen or so pounds of air above every inch of ground.

The ground is *very* thick. By my math less than 20 feet of ground is as heavy as all of the air above it. As much as the atmosphere may insulate the surface, the ground itself insulates the core *way* more.
