Question

distinguish between:
1)troposphere and stratosphere
2)mesosphere and thremosphere

Answer 1

Troposphere is layer of atmosphere within 1st 10-15 km and it consist of our 90%of atmosphere , here temp decreases with altitude whereas in stratosphere is within 30km from earth surface ,here exist the ozone layer which increases temperature with altitude.

Mesosphere is within 50-85 km below thermosphere and above stratosphere here temp falls with altitude whereas in thermosphere extends above 90km and exist just above mesosphere here temperature is too high.
