WebThe stratosphere (11–50 km) is characterized by increasing amounts of ozone, O 3. From 0.04 parts per million, in the troposphere, ozone increases to a maximum of about 10 ppm at 25–30 km. The ozone is formed in a two-step process initiated by ultraviolet radiation, which provides enough energy to split the dioxygen into two oxygen atoms. Web15 mrt. 2024 · The ionosphere contains plasma and is made up of three layers. The lowest is called the D-region, reaching from 47-59 miles (75-95 km) above the surface of the Earth, and does not contain many ions. The next layer is called the E-region, reaching from 59-93 miles (95-150 km) and containing a slightly higher concentration of ions. small towns near rochester ny https://quingmail.com

WebThe ionosphere is an atmospheric layer located at an altitude of about 50 kilometers and 500 kilometers. It has an extremely low density and is traversed by strong radiation as ultraviolet light, which in turn is highly ionized. This ionization causes the electronic bonds of the atoms to break down producing ions of different charges.
