Question

which conditions resulted in the erosion of larger rocks, like the one circled in the image? check all that apply.
low gradient, low velocity
low gradient, high velocity
low gradient, high volume
high gradient, low velocity
high gradient, high velocity

Explanation:

Eroding and moving large rocks requires enough force from flowing water. A high gradient (steep slope) creates faster water flow, and high velocity means the water has the energy to dislodge and carry larger, heavier rocks. Low gradient or low velocity conditions lack the necessary energy to move large rocks.

Answer:

high gradient, high velocity
