Question

which of the following is a natural hazard that can be increased by deforestation? a soil erosion b earthquakes c air pollution

Explanation:

To solve this, we analyze each option:

• Option A: Trees' roots hold soil. Deforestation removes trees, so soil erosion (a natural hazard) increases as there's less root support to prevent soil from being washed/eroded away.
• Option B: Earthquakes are caused by tectonic plate movements, not deforestation.
• Option C: Air pollution is mainly from human activities like burning fossil fuels, not directly linked to deforestation (deforestation affects air quality via CO₂ but isn't the primary cause of air pollution as a natural hazard - and air pollution is more of a human - induced or mixed issue, not a natural hazard increased by deforestation in the direct sense of soil erosion).

So the correct option is A.

Answer:

A. soil erosion
