Consider the following statements about the layers of atmosphere :
1. Stratosphere has higher temperature than Tropopause because it has lesser number of gases; hence
scattering of the incoming solar radiation is less.
2. The temperature of Tropopause above the equator is less than the temperature of Tropopause above the
poles.
scattering of the incoming solar radiation is less.
2. The temperature of Tropopause above the equator is less than the temperature of Tropopause above the
poles.
Which of the statements given above is/are correct?
- a)1 only
- b)2 only
- c)Both 1 & 2
- d)Neither 1 nor 2
Correct answer is option 'B'. Can you explain this answer?

Stratosphere has higher temperature but the reason is the presence of ozone gas which absorbs the ultraviolet part of incoming solar radiation, raising the temperature. In fact more is the amount of gases in the atmosphere, greater is its heating. It is the reason that near the surface of earth, where the density of atmosphere is maximum the temperature is highest.
Because tropopause is at the height of about 18 km & 8 km at equator & poles respectively, the tropopause temperature above equator is of about - 80 degree centigrade& above poles is - 45 degree centigrade.
Hence, only statement 2 is correct.

Explanation:
Statement 1: Stratosphere has higher temperature than Tropopause because it has lesser number of gases; hence scattering of the incoming solar radiation is less.
The statement is incorrect.
- The temperature in the atmosphere generally decreases with increasing altitude. However, there is a region in the atmosphere called the stratosphere where the temperature increases with increasing altitude.
- The temperature increase in the stratosphere is primarily due to the presence of ozone (O3) molecules. Ozone absorbs the incoming ultraviolet (UV) radiation from the Sun and heats up the surrounding air.
- The stratosphere is located above the troposphere, which is the lowest layer of the atmosphere. The troposphere contains most of the Earth's weather and the majority of the atmosphere's gases, including water vapor and carbon dioxide.
- The tropopause is the boundary between the troposphere and the stratosphere. It is characterized by a stable layer of air where the temperature remains constant or even slightly increases with increasing altitude.
- The stratosphere is not characterized by a lower number of gases compared to the troposphere. In fact, the stratosphere contains a significant amount of gases, including nitrogen, oxygen, and traces of other gases.
- The increase in temperature in the stratosphere is primarily due to the absorption of UV radiation by ozone, not because of a lower number of gases.
Statement 2: The temperature of Tropopause above the equator is less than the temperature of Tropopause above the poles.
The statement is correct.
- The tropopause is the boundary between the troposphere and the stratosphere. It is characterized by a stable layer of air where the temperature remains constant or even slightly increases with increasing altitude.
- The temperature of the tropopause varies depending on the location. Above the equator, the temperature of the tropopause is generally lower compared to the temperature above the poles.
- This temperature difference is primarily due to the difference in solar radiation received at different latitudes. The equator receives more direct sunlight throughout the year, leading to higher temperatures in the lower atmosphere and relatively lower temperatures in the upper atmosphere.
- In contrast, the poles receive less direct sunlight, resulting in lower temperatures in the lower atmosphere and relatively higher temperatures in the upper atmosphere.
- Therefore, the temperature of the tropopause above the equator is generally lower than the temperature of the tropopause above the poles.
In conclusion, statement 1 is incorrect, and statement 2 is correct.
