If a Forested Area Surrounding a Stream is Cleared of Trees

Question

If a forested area surrounding a stream is cleared of trees, what has been found to happen?
A) Increased import of nutrients to the soil
B) Decreased rates of soil and rock weathering
C) Increased run-off of water
D) Decreased rates of chemical leaching
E) Increased denitrification

Accepted Answer

When trees are removed from an area surrounding a stream, there is less vegetation to absorb rainfall, leading to increased run-off of water. This can cause soil erosion and affect water quality in the stream.
