Question

Quizplus · Accepted Answer

Frost wedging occurs when water infiltrates cracks in rocks, freezes, and expands, causing the rock to break apart. This process is particularly effective in cold, frost-prone environments, such as mountaintops and high latitudes. As a result, talus slopes - piles of loose, broken rock fragments at the bottom of steep cliffs and mountainsides - are often formed through frost wedging. Thus, the correct answer is B.
