Question

Quizplus · Accepted Answer

The environmental lapse rate of an air layer next to the ground is strongly influenced by the heating or cooling of the ground. During the day, the ground is heated by the Sun, and the air in contact with the ground is also heated. This results in a steep environmental lapse rate, where the temperature decreases rapidly with height. At night, the ground cools down, and the air in contact with the ground also cools down. This results in a shallow environmental lapse rate, where the temperature decreases slowly with height. Therefore, the heating or cooling of the ground strongly influences the environmental lapse rate.
