Question

Quizplus · Accepted Answer

Frost wedging is the mechanical weathering process that occurs when water seeps into cracks in rocks or soil, freezes and expands, causing the rock to break apart. This process is most often seen in cold, high-altitude areas and is a significant contributor to the formation of talus slopes, which are large piles of broken rock fragments. Therefore, the correct answer is B, talus slopes.
