The stability of the air layer close to the earth's surface can vary markedly.Much of this variation is caused by:
A)changes in wind speed.
B)changes in pressure.
C)changes in wind direction.
D)changes in heating or cooling of the surface.

Changes in heating or cooling of the surface can cause variations in the stability of the air layer close to the earth's surface. This is because the temperature of the surface affects the temperature of the air above it, which in turn affects the stability of the air layer. For example, if the surface is heated by the sun, the air above it will also be heated and may become less stable, while if the surface is cooled, the air layer may become more stable. Changes in wind speed, wind direction, and pressure can also have some effect on the stability of the air layer, but these are usually secondary factors.
