Stratosphere *the stratosphere is layered in temperature because it is heated from above absorption *It is layered by temperature with warmer layers higher up and cooler layers farther down *99% of air is located in the troposphere and stratosphere *6 mile - 30 miles from ground |
|
Thermosphere *It is the first layer exposed to sun *Temperature can reach up to 1500degC or higher *Scientists can't measure the temp because air is so thin up there *Meteorites usually disintegrate in this layer. *UV light causes ionization (electrons leave the atom causing ion to form, ions are charged atom/particles) to occur *Auroras - ionized particles interacting with the water particles in the atmosphere. *up to 300 miles from ground Ionosphere *ionized by solar radiation *Northern lights (Auroras - ionized particles interacting with the water particles in the atmosphere.) happen in this layer *It bounces and transmits radio signals back to earth. *Form the inner edge of the magnetosphere - area of space outside the earth that is influenced by the magnetic field of the earth. |
