Web22 nov. 2024 · The ozone layer is one layer of the stratosphere, the second layer of Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet. The stratosphere gets its name because it is stratified, or layered: as elevation increases, the stratosphere gets warmer. WebLayers of the ionosphere. Historically, the ionosphere was thought to be composed of a number of relatively distinct layers that were identified by the letters D, E, and F. The F layer was subsequently divided into regions F 1 and F 2. It is now known that all these layers are not particularly distinct, but the original naming scheme persists. northern wisconsin snowmobile trail map
