Why doesn't air temperature increase or decrease uniformly with altitude, just like air pressure decrease uniformly with altitude? Give example of the different possible scenarios.
Answers
Answer:
The troposphere is heated from the ground, so temperature decreases with altitude. Because warm air rises and cool air sinks, the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun's harmful UV radiation.
Air pressure changes with altitude
Air is all around us, but we cannot see it. Gravity from the Earth pulls air down - this is called air pressure. We don't feel this pressure because our bodies push an equal amount of pressure outward. This graph shows how air density and air pressure changes with altitude (the distance above sea level). Barometers are used to measure air pressure in milibars.
Temperature changes with altitude
The atmosphere is divided into different layers depending on how temperature changes. Take a look at the graph below to see how temperature changes with altitude.
