The coolness in only at fairly shallow depths, and is present simply because the warming effect of the sunlight never penetrates any deeper. However, go deep enough, and the underground is not cool at all; in fact, in gets hotter and hotter until it becomes the liquid magma that erupts from volcanoes as lava. Ask any deep miner or oil rig driller, or refer to the dramatic example of geysers like Old Faithful, which are created when ground water reaches that hot depth.
