Answer:
Here are my notes on temperature of both soil and air: If the air above the land is cold and the temperature of land or soil is warm this heated light air will rise upwards and cold and dense air mass will settle on the ground as a result of the amount of humidity in the air will increase.
This phenomenon time may lead to the development of the front of warm and cold air also the formation of a cyclone takes place in a similar manner if it takes place in water.
This could also create a temperature inversion type of conditions at night time. on average the earth temperature changes from 2-3 degrees per 100 meters in greater depths and increases from 1° to 5° C/100 m.
The air temperature would drop quickly compared to the soil because the difference between solid and gas. But the ground will stay cooler longer than the air because it contains it better than the air.\
Hope this helps, have a great day and stay safe! :) :D :3
