In which environment is erosion likely to have the most impact? a steep hillside with little vegetation and strong downpours
a steep hillside covered with grasses and mild downpours
a flat valley with little vegetation and heavy downpours
a flat valley covered with grasses and mild downpours

A. Steep hillside, little vegetation, strong downpours

Explanation:

between a steep hill and a flat valley, the hill is more likely to be affected because of gravity. with a valley theres less places for the dirt to actually move to. So C and D are not correct

a lack of vegetation and heavy downpour is the perfect condition for erosion. plants' root system makes dirt and rock more stable. without a lot of roots to hold the dirt in place and absorb water before it runs over the rocks and breaks them down, heavy rain would be a lot more likely to erode the area. so B isnt right either
