The Earth’s atmosphere thins as altitude increases.

|
The lower the elevation, the higher the temperatures.

Detailed explanation-1: -When the sun’s rays strike Earth’s surface near the equator, the incoming solar radiation is more direct (nearly perpendicular or closer to a 90˚ angle). Therefore, the solar radiation is concentrated over a smaller surface area, causing warmer temperatures.
Detailed explanation-2: -Earth’s axis always points in the same direction. Because of this, the part of Earth that receives the most direct rays from the Sun changes as the Earth travels around the Sun. At the equinox, the Sun’s rays shine most directly on the equator, and the Northern and Southern Hemispheres get the same amount of Sunlight.
Detailed explanation-3: -At higher latitudes, the Sun’s rays are less direct. The farther an area is from the equator, the lower its temperature. At the poles, the Sun’s rays are least direct. Much of the area is covered with ice and snow, which reflect a lot of sunlight.
