The thermosphere is the outer layer of the earth it is 1,800 degrees and at the top there is a thin layer it also extends 80 km from earth surface
the meosphere is 55 km from earth it is it called middle sphere the tempeture is -90 degrees which is cold.
the stratophere is where the protective ozone layer floats it is from 16 to 50km did you know that it holds 20% of molecules and as it goes away it gets warmer.
