Multiple choice

What are some of the health effects of urban heat islands?

  1. Heatstroke.

  2. Dehydration.

  3. Respiratory problems.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Urban heat islands can have a number of negative health effects, including heatstroke, dehydration, and respiratory problems. Heatstroke is a condition that occurs when the body's temperature rises to dangerous levels. Dehydration occurs when the body does not have enough water. Respiratory problems can be caused by the high levels of air pollution that are often found in urban areas.
