•1.Cooler, Denser air & Hotter, less dense air.
-Troposphere is less hot than stratosphere.
Colder air stays below.
Hotter air stays above.
2.Cooler, Denser air & Hotter, less dense air.
-Cooler air is denser.
Dense things are heavy.
Heavy things stay below.
Visa-versa.
3.Air pressure and the density of the air also decrease with altitude.
-Temperature is directly proportional to pressure
If air pressure increases, the temperature must increase.
If air pressure decreases, the temperature decreases.
Up above @stratosphere pressure is less.
Less pressure; less temperature.
Less temperature; colder air.
Because of no air turning over, Stratosphere is still hotter than Troposphere even if its pressure is low.
.
4.Why does temperature increase with altitude in the stratosphere?
-In the stratosphere, temperature generally increases as altitude increases due to the increasing absorption of ultraviolet radiation by the ozone layer.
Why Troposphere air is cooler than Stratosphere?
- Troposhere is lowest layer.
- It's part of the biosphere.
- Warm air at the surface rises and colder, denser air at altitude descends to take its place.
- The air in troposhere is well mixed.

Why does air temperature increase with pressure?
The energy added as work during the compression of a gas leads to an increase in pressure and temperature.
