How does soil temperature relate to air temperature?

Answer 1

Soil temperature directly affects air temperature.

There are two main ways that the temperature of the soil can influence the temperature of the air: first, heat is transferred through conduction, which occurs when warm air touches warm soil and warm soil heats the air that comes into contact with it.

The transfer of latent heat from soil to air has a larger effect. The temperature of the soil can heat water in the soil, which can then evaporate and carry the heat energy from the soil into the atmosphere. As the water vapor cools, the latent heat it contained is released into the atmosphere as sensible heat.

Soil temperature lags behind air temperature changes due to differences in heat capacity and conductivity. Warmer air leads to increased soil temperature, affecting biological and chemical processes.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
