temperature heats in thermosphere
Above 120 miles (200 km) above sea level, temperatures in the thermosphere can vary between 600Â° and 2000Â°C (1100 and 3600Â°F). The actual temperature range is h â¦ ighly dependent on solar activity. A longer answer The thermosphere is a layer of Earth's atmosphere above the mesosphere. The thermosphere extends from 50 to 55 miles (80-90 km) above sea level, with the upper limit undefined. The temperature in the thermosphere initially rises rapidly with heights up to about 120 miles (200 km) and thereafter increases more slowly.
