![]() ![]() How did weathering destroy New Hampshire’s Old Man in the Mountain? Water migrated along fractures in the rock, where it froze and wedged the rock apart. Which of the following climates would have the greatest degree of ice wedging? Cold in the winter, warm in the summer, and with moderate precipitation. Which of the following climates would have the greatest degree of ice wedging? Ice wedging is when a drop of water falls into a crack in the sidewalk and freezes and makes the crack bigger. Can you see the sidewalk and how its pushed up, this is because of the tree root. This is are class near an example of root wedging. Chemical weathering occurs when roots release chemicals, like acid, which then break down the rocks. Mechanical weathering occurs when roots grow and cause the rock to break (just like the roots that crack the sidewalk). Plants can cause both mechanical and chemical weathering. What is the sequence of events in weathering caused by plants? What is the first step in the process of ice wedging? Ice melts in cracks in rocks. What is the first step in the process of ice wedging? When the temperature cools below freezing, the water turns to ice and expands. When the temperature is warm, water works its way into cracks in rock. Ice wedging happens because water expands as it goes from liquid to solid. If this happens many times (water seeping into the crack, freezing, expanding, and widening the crack), the crack will eventually break completely. While freezing, the water expands and causes the crack to widen. Ice wedging happens whenever water is able to get into small cracks in rock or other material and freeze.
