Ice segregation results in growth of ice needles … WebWhat is the effect of freeze-thaw weathering? Weathering is the breakdown of rock in situ (in the place where it is). Freeze-thaw is when meltwater or rain gets into cracks in the bedrock, usually the back wall. At night the water freezes, expands and causes the crack to get larger. Eventually, the rock will break away.
