Question

scientists predict that the human population will continue to increase. which two events will likely happen as a result?
a. more fossil fuels will be used for cars.
b. more oxygen will form in the atmosphere.
c. more trees will be cleared from land.
d. more water will flow into watersheds.

Explanation:

• Option A: With a growing population, there will be more people needing transportation. Cars are a common mode, and many cars run on fossil fuels, so more fossil fuels will likely be used for cars.
• Option B: An increasing human population means more consumption of resources, more industrial activities (which often produce pollutants and consume oxygen - related processes like combustion), and more deforestation (trees produce oxygen). Overall, it is less likely that more oxygen will form in the atmosphere.
• Option C: A larger population needs more space for housing, agriculture (to feed the population), and infrastructure. This often leads to more trees being cleared from the land.
• Option D: A growing population usually leads to more water consumption (for domestic use, industry, agriculture) and more pollution of water sources. It is not likely that more water will flow into watersheds as a result of a growing population.

Answer:

A. More fossil fuels will be used for cars, C. More trees will be cleared from land.
