Question

Why does temperature increase with altitude in the stratosphere?

Answer 1

The temperature in the stratosphere increases with altitude because of the absorption of ultraviolet (UV) radiation from the sun by ozone molecules. In the stratosphere, ozone molecules absorb UV radiation, which causes the molecules to break apart and form oxygen molecules. This process releases energy, which heats up the surrounding air. As altitude increases in the stratosphere, there is a higher concentration of ozone molecules, leading to more UV absorption and a higher temperature. This is known as the ozone layer, which acts as a natural barrier that protects the Earth's surface from harmful UV radiation.
