Explanation:
Detailed explanation-1: -Near the Earth’s surface, air gets cooler the higher you climb. As you climb a mountain, you can expect the air temperature to decrease by 6.5 degrees C for every 1000 meters you gain. This is called the standard (average) lapse rate.
Detailed explanation-2: -As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.
Detailed explanation-3: -The rate of decline is surprisingly fast: around 1°C for every 100m, and continues all the way up to the so-called tropopause around 12km above the Earth. At these altitudes, barely 10 per cent of the atmosphere remains, and the air pressure is so low that the temperature falls to a lethally cold-55°C.
