Ionosphere
The ionosphere ( / aɪ ˈ ɒ n ə ˌ s f ɪər / [1] [2] ) is the ionized part of Earth's upper atmosphere , from about 60 km (37 mi) to 1,000 km (620 mi) altitude, a region that includes the thermosphere and parts of the mesosphere and exosphere . The ionosphere is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere . It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth . [3]
