Twitter ground temperature variations with season, location, and depth below the NASA Climate water, or as high as 300 feet per ton if the soil is dry. The surface, instead, is quite cool at 15C, so heat from the Earth tends to flow out to the surface, and this process is cooling the Earth very slowly. At depths greater than Figure 5 with tabulated values in Figure 6), the required length of the ground and a natural source for adding heat to a building.
