Why the temperature in higher level places( from sea) is lesser than the lower level places?

Question

Take Hill places they are very cool but the plains are very hot.

Answer 1

The atmosphere is cooler than the surface temp because of the airs density.

Answer 2

The higher up you go the cooler it becomes.. This is because as the hot air rises from the hills it cools down rapidly.. It cools down because the air molecules become compressed and do not expand as much therefore making higher places cooler.

Answer 3

Both the density and pressure of the atmosphere decrease with altitude. This is because atmospheric pressure depends on the weight of the overlying atmosphere. It decreases logarithmically with altitude, following something called the hydrostatic equation. Because of this decrease in pressure, a rising air parcel expands and cools (because it does "work" P dV on the surrounding atmosphere). The average rate of decrease is -6.5 degrees (K or C) per km in the lower atmosphere.

Answer 4

Because atmosphere is not directly heated by solar radiation.The solar radiation after getting reflected from the earth's surface starts heating the atmosphere from the bottom.That means the surface is heated first and the atmosphere is heated either by the reflected solar radiation or convection and conduction from the surface.

Answer 5

as the altitude increases, the temperature decreases
