Question

Quizplus · Accepted Answer

With increase in population, more people settle in marginal lands which increases their vulnerability to hazardous processes like landslides, floods, and wildfires.

Answer: B 
 Population growth can lead to land-use changes, deforestation, urbanization and other land reclamation activities that increase the frequency and magnitude of natural disasters.

Answer: C 
 Areas with high population densities are more likely to be affected by catastrophic events like volcanic eruptions, earthquakes, and hurricanes.

Answer: D 
 This statement is incorrect as earthquake magnitude is determined by the release of energy from the earth’s crust and not the population residing in the area.
