Recall the Bormann-Likens controlled experiment in the forested valleys of New Hampshire. Which statement best describes the effects of water flowing out of deforested areas into undisturbed areas?
A) The amount of water flowing out of the deforested valley following rain increased by 30-40%, and soil erosion increased.
B) The amount of water flowing out of the deforested valley decreased by 10-20%, and soil erosion decreased.
C) The flow of water did not change, but soil erosion increased.
D) Other types of plants took the place of the trees, preventing deforestation from affecting the flow of water.
E) Eroding soil dammed up the river, preventing the flow of water.

In the Bormann-Likens experiment, the deforested area experienced an increase of 30-40% in water flow following rain, which resulted in increased soil erosion. This increased water flow was due to the lack of vegetation and tree roots to absorb and slow down the water. The undisturbed areas did not experience any significant changes in water flow or soil erosion.
