Question

question #7
what is a possible unintended benefit of long-term overuse of fossil fuels like coal?
a increases the salinity of water
b reduces the temperature of surface water sources
c increases the development of renewable energy technologies
d reduces the amount of incoming solar radiation

Explanation:

• Option A: Fossil fuel overuse doesn't directly increase water salinity; this is unrelated.
• Option B: Fossil fuel use contributes to global warming, which would likely increase surface water temperatures, not reduce.
• Option C: Long - term overuse of fossil fuels leads to concerns about resource depletion and environmental issues (like climate change). This motivates research and development of renewable energy technologies as an alternative, so this is a possible unintended benefit.
• Option D: Fossil fuel use doesn't reduce incoming solar radiation; solar radiation is from the sun and not directly affected by fossil fuel use in this way.

Answer:

C. increases the development of renewable energy technologies
