If the center of the earth is so hot why is the ground cooler if you dig down a few feet?

    This is because most of the heat we feel near sea level is not from the molten core, but from the sun’s heat. Radiation hits the surface of the ground and heats it up, but, depending on the material you are digging through, the heat will have penetrated less as you go further down. The ground a few feet down is also more likely to be wet, as it is nearer the water table and isn’t as affected by evaporation as the surface. This extra moisture can make it feel cold and clammy.
