What causes the temperature to increase in the stratosphere?
A
Nitrogen
B
Ozone
C
Water Vapor
D
carbon dioxide
Explanation: 

Detailed explanation-1: -In this region the temperature increases with height. Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average-60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere.

Detailed explanation-2: -Atmospheric ozone has two effects on the temperature balance of the Earth. It absorbs solar ultraviolet radiation, which heats the stratosphere. It also absorbs infrared radiation emitted by the Earth’s surface, effectively trapping heat in the troposphere.

Detailed explanation-3: -Above the tropopause lies the stratosphere, where temperature increases with altitude. Temperatures increase because ozone molecules in the stratospheric ozone layer absorb solar energy within the stratosphere. Air flow in the stratosphere is much less turbulent than in the troposphere.

Detailed explanation-4: -In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere’s gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection.

Detailed explanation-5: -The increase of temperature with altitude is a result of the absorption of the Sun’s ultraviolet (UV) radiation by the ozone layer. The temperature inversion is in contrast to the troposphere, near the Earth’s surface, where temperature decreases with altitude.
