How does urbanization commonly affect local weather patterns?

• A. By increasing humidity levels
• B. By creating heat islands
• C. By reducing precipitation
• D. By enhancing wind speeds

Answer: (B)

Urbanization alters local weather patterns primarily by creating heat islands. Urban areas, due to extensive concrete, asphalt, and other materials that absorb and retain heat, tend to be significantly warmer than surrounding rural areas. This localized increase in temperature can profoundly influence weather conditions. The heat generated from buildings, vehicles, and industrial activity contributes to the urban heat island effect, which can lead to increased temperatures that affect local climate. As a result, cities may experience warmer nights because these surfaces retain heat longer than natural landscapes like forests or fields. This temperature difference can also affect wind patterns and local air movements, as the warmer air over the urban area can rise and create upward air currents, potentially influencing precipitation patterns as well. However, the most direct and noticeable impact is the increase in temperature, which is central to the concept of urban heat islands, making this the correct answer.
