Question

select the correct answer.
the worldwide use of cleaner energy sources could lead to which of the following results?
a. rise in ocean levels
b. reduction in acid rain
c. increased desertification in the sahel
d. decreased desalination plants in the middle east

Explanation:

• Option A: Clearer energy sources (like renewables) reduce greenhouse gases, which mitigate climate change effects like ocean level rise drivers (melting ice). But cleaner energy use itself doesn't directly cause ocean level rise; it helps prevent it. So A is incorrect.
• Option B: Acid rain is caused by pollutants like sulfur dioxide and nitrogen oxides from burning fossil fuels. Cleaner energy sources (e.g., solar, wind) produce less of these pollutants. So using cleaner energy would reduce acid rain. This is correct.
• Option C: Desertification in the Sahel is due to factors like overgrazing, climate variability, and poor land management, not directly related to cleaner energy use. So C is incorrect.
• Option D: Desalination plants in the Middle East are for water supply, related to water scarcity, not directly to energy source type (cleaner energy use doesn't directly decrease desalination plants; in fact, some clean energy can power them). So D is incorrect.

Answer:

B. reduction in acid rain
