Ionosphere atmosphere
Web1 nov. 2024 · The ionosphere is the layer of the Earth that is ionized by cosmic and solar radiation. It lies 46 to 621 miles above the Earth’s surface. The atoms in this layer have been stripped off one or more electrons by cosmic rays or intense energy from the sun and are therefore charged. WebThe mesosphere ranges from 50km to 85km, and is the layer wherein most meteors are incinerated before reaching the surface. The thermosphere extends from an altitude of 85km to the base of the exosphere at 690km …
