Higher up in the troposphere, where less heat from the surface warms the air, the temperature drops. Typically, the temperature drops about 6.5° C with each increase in altitude of 1 kilometer (about 3.6° F per 1,000 feet). The rate at which the temperature changes with altitude is called the "lapse rate".

The exosphere is the outermost layer of Earth's atmosphere (i.e. the upper limit of the atmosphere). It extends from the exobase, which is located at the top of the thermosphere at an altitude of about 700 km above sea level, to about 10,000 km (6,200 mi; 33,000,000 ft) where it merges into the solar wind.
