conditions suitable for flying plains
contains ozone
mesosphere... extends up to 80 km
characteristics.... above stratosphere
meteorites burn up here on entering from the space
thermosphere.... extends between 80 to 100 km
characteristics... temperature very high due to increasing height
lies above mesosphere
helps in radio transmission and radio waves transmitted from the earth are reflected back to earth by this layer
exosphere... uppermost layer
characteristics... lies above thermosphere
has very thin air
light gases like helium and hydrogen float into the space from here
