Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : The temperature in most of the metropolitian cities is increasing alarmingly.
Reason (R) : Greenbelt is decreasing in urban areas.
In the light of the above statements, choose the most appropriate answer from the options given below :
Assertion Analysis
Assertion (A) states that the temperature in most metropolitan cities is increasing alarmingly. This is generally considered correct due to phenomena like the Urban Heat Island (UHI) effect, where urban areas are significantly warmer than surrounding rural areas.
Reason Analysis
Reason (R) states that greenbelts are decreasing in urban areas. This is also typically correct, as urbanization often leads to the conversion of green spaces into built environments.
Relationship Evaluation
While the reduction of greenbelts (R) is a significant contributing factor to the increase in urban temperatures (A) by reducing cooling effects and increasing heat absorption, it is not the sole or complete explanation.
- Increased industrial activity, vehicular emissions, waste heat from buildings and air conditioning, and the thermal properties of construction materials also contribute significantly to the UHI effect and rising temperatures in metropolitan areas.
- Therefore, R is correct and contributes to A, but it does not fully explain A by itself.
Based on this analysis, both statements are correct, but the reason does not fully explain the assertion.
Final Answer Selection
The most appropriate option is that both (A) and (R) are correct, but (R) is not the correct explanation of (A).
