Freeze-thaw weathering is a type of physical weathering, meaning it breaks rocks apart without changing their chemical composition. Instead of altering the minerals inside the rock, it relies on mechanical force caused by the expansion of water as it freezes. Water is unique because it expands when it turns into ice, increasing in volume by … Read more

Freeze-thaw weathering is one of the most common and powerful natural processes that slowly breaks down rocks over time. It happens in places where temperatures regularly rise above and fall below freezing. Water seeps into cracks in rocks, freezes, expands, and eventually forces the rock to split apart. This repeated cycle can transform even the … Read more
