​In which of the layers temperature decreases as altitude increases?

A. Thermosphere
B. Troposphere
C. Mesosphere
D. Stratosphere

Choose the correct answer from the options given below:

Correct option is B

The temperature in the Troposphere and Mesosphere decreases as altitude increases.

• In the Troposphere, the temperature decreases with altitude because the layer is primarily heated by the Earth's surface, and as you move higher, you move away from this heat source.
• In the Mesosphere, the temperature also decreases with altitude due to the decreasing density of air and the lack of sufficient absorption of solar radiation.

In contrast, the Stratosphere experiences an increase in temperature with altitude due to the absorption of ultraviolet radiation by the ozone layer, and the Thermosphere also has increasing temperatures with altitude due to the absorption of high-energy solar radiation.

Information Booster:

1. Troposphere: This is the lowest layer of the atmosphere, where weather phenomena occur, and temperature generally decreases with altitude.
2. Mesosphere: This layer lies above the stratosphere and below the thermosphere, and it also experiences a decrease in temperature with altitude.
3. Stratosphere: In the stratosphere, temperature increases with altitude due to the absorption of ultraviolet (UV) radiation by the ozone layer.
4. Thermosphere: The thermosphere is the layer above the mesosphere, where the temperature increases with altitude due to the absorption of high-energy solar radiation by atoms and molecules.
