Question

Quizplus · Accepted Answer

The Earth's atmosphere extends to a maximum height of about 10,000 km, but more than 90% of it lies below an altitude of 16 km. The mesosphere, which extends from 50 to 80 km above the Earth's surface, is the coldest layer of the atmosphere, while the thermosphere, which extends from 80 to 600 km, is the hottest layer. However, the entire atmosphere lies below an altitude of 100 km, which is known as the Kármán line and is widely considered to be the boundary between the Earth's atmosphere and outer space. Therefore, option D) 100 km is the best choice.
