Quizplus · Accepted Answer

The term "talus" specifically refers to the rock debris that accumulates at the base of steep slopes through gravitational action. Option A, exfoliation, refers to a specific weathering process where layers of rock peel away due to pressure release. Option C, slump, and option D, creep, both refer to types of mass wasting or movement of material down slopes, but do not specifically refer to the accumulation of rock debris at the base of slopes. Option E, vesicles, refers to small cavities or pockets within rocks caused by gas bubbles during solidification.
