Question

What is an example of physical weathering?
Answered by GPT 3.5
An example of physical weathering is frost action or freeze-thaw weathering. This occurs in areas where temperatures fluctuate above and below the freezing point. Water enters cracks in rocks and then freezes, causing it to expand and exert pressure on the surrounding rock. This repeated freezing and thawing weakens the rock, eventually causing it to break apart.
