- Heat conducts by Fourier's law with thermal diffusivity D = lambda/C, typically 0.2-0.8e-6 m2/s in mineral soils
- The daily temperature wave damps with depth: the amplitude falls by a factor e at d = sqrt(2D/omega), about 0.12 m (daily) and 2.2 m (annual) for D = 0.5e-6 m2/s, leaving under 5% of the surface daily swing below about 0.35 m
- Snow insulates: with conductivity 0.1-0.5 W/m/K, about 30 cm of snow can hold soil near 0 C when air is -20 C
