Footer Social Media Navigation Ball park: 30 feet gets out out of the seasonal variation, but 12 feet eliminates about 2/3 of the annual variation. The common arctic form is called tundra. In addition, the thermal conductance of the rocks (changing as the rock minerals change with deeper depths), the area heat flow, and the rock density (sedimentary rocks are less dense than basement rocks) are used to calculate the deeper temperatures.
