Consider the following statements:Statement-I: The atmosphere is heate...
- Statement-I is correct because the atmosphere is indeed heated more by incoming solar radiation than by terrestrial radiation. The sun's energy is the primary source of heat for the Earth's atmosphere.
- Statement-II is also correct as carbon dioxide and other greenhouse gases in the atmosphere are indeed good absorbers of long wave radiation. They absorb and re-emit infrared radiation, contributing to the greenhouse effect which warms the Earth's surface.
- However, Statement-II does not directly explain Statement-I. While both statements are individually correct, there is no direct explanatory link between them. Solar radiation heating the atmosphere more than terrestrial radiation is a function of the Earth's energy balance and the properties of greenhouse gases, but the specific absorption of long wave radiation doesn't directly tie into the comparison of solar vs. terrestrial heating.

Understanding Statement-I and Statement-II
Both statements relate to the processes of atmospheric heating and the role of greenhouse gases.
Statement-I: The atmosphere is heated more by incoming solar radiation than by terrestrial radiation.
- The Earth's atmosphere absorbs a significant portion of solar radiation, which primarily comes from the sun.
- The incoming solar radiation heats the surface of the Earth, which in turn emits long-wave (terrestrial) radiation back into the atmosphere.
- However, the direct warming effect of solar radiation on the atmosphere is typically greater than that of terrestrial radiation.
Statement-II: Carbon dioxide and other greenhouse gases in the atmosphere are good absorbers of long wave radiation.
- Greenhouse gases like carbon dioxide (CO2), methane (CH4), and water vapor are indeed effective at absorbing long-wave radiation emitted from the Earth's surface.
- This absorption leads to the greenhouse effect, where these gases trap heat in the atmosphere, contributing to its warming.
Analysis of the Statements
- Both statements are accurate: Statement-I correctly identifies the predominant source of atmospheric heat as solar radiation, while Statement-II correctly describes the role of greenhouse gases in absorbing long-wave radiation.
- However, Statement-II does not directly explain Statement-I. The heating of the atmosphere by solar radiation occurs independently of the greenhouse effect, which is a separate process that influences temperature retention in the atmosphere.
Conclusion
- Thus, the correct choice is option 'B': Both Statement-I and Statement-II are correct, but Statement-II does not explain Statement-I. The relationship between these phenomena demonstrates the complexity of atmospheric dynamics.
