Tropopause is the top of troposphere, which in turn is the lowest part of
the
atmosphere (this definition is based on the profile of mean temperature).
Troposphere is the region where all the weather phenomena take place and
consist some 80-85 percent of the total mass of the atmosphere. Right
above troposhere is the stratosphere (tropopause is between these) and
above stratosphere is the mesosphere (and between these is the
stratopause). Above mesosphere is thermosphere, but the air is already
so thin that it is more like wandering molecules and ions that a gas.
Hope this helped.
