WebWhat is weathering? The wearing away of the land by the sea, wind, ice and rivers. The deposition of material by the sea, wind, ice and rivers. The movement of material by the sea, wind, ice and rivers. The break down of rock in situ by the action of rainwater, extremes of temperature, and biological activity. WebFreeze-thaw weathering occurs when rocks are porous (contain holes) or permeable (allow water to pass through). Water enters cracks in the rock. When temperatures drop, the water freezes and expands causing the crack to widen. The ice melts and water makes its way deeper into the cracks. The process repeats itself until the rock splits entirely.
