Question

a city has experienced increased temperatures over the past decade. scientists note that the region has experienced rapid urban growth. which of these best explains how urbanization is contributing to the citys climate change? a urban areas have more wind flow, which helps cool the environment. b paved areas trap heat and limit vegetation that would normally cool the air. c urban surfaces reflect solar radiation, reducing temperature. d urbanization reduces greenhouse gas emissions.

Explanation:

Urban areas have a lot of paved surfaces like roads and buildings. These surfaces absorb and trap heat. Also, the reduction in vegetation due to urban - growth means less transpiration and shading, which would normally cool the air. Option A is incorrect as urban areas often have less wind flow due to the built - up environment. Option C is wrong because urban surfaces usually absorb rather than reflect solar radiation. Option D is incorrect as urbanization generally increases greenhouse gas emissions.

Answer:

B. Paved areas trap heat and limit vegetation that would normally cool the air.
