The deforestation of a wooded area increases erosion, resulting in increased sediment at the bottom of a nearby river. This leads to increased flooding in the area. Which of the following terms best defines this chain of events? A) uniformitarianism B) a positive feedback loop C) a negative feedback loop D) environmental unity

C since the other ones dont even make sense ... It isnt positive if its flooding, it isnt unity because its destroying everything

Answer: Option B

Explanation:

The positive feedback loop can be defined as the phenomenon in which the effect of the nature is defined as positive loop.

The chain of events here are deforestation, which increases sedimentation and this sedimentation ultimately leads to the flooding.

The intensity of the event is increasing with the course of time. The event started from deforestation and ended on flooding.
