How does the weather affect the earth's surface?
There is an actual term used when the weather shapes the Earth. The term is weathering. Weathering is the wearing down or dissolving of materials on Earth's surface. Weathering can be caused by wind, ice, precipitation, and changes in temperature. Weathering can wear away any exposed surface on earth over time. It can cause rough surfaces to become smooth, much like a tumbler smooths a rock.
An obvious example of weathering is the change of the landscape at the sea. The tides can cause the beach to become smaller or larger. The wind can cause dunes to become taller or shorter. Potholes are even caused by a form of weathering caused ice wedging. Water seeps into cracks in the ground. When the water freezes and expands. This forces can cause the roads to break apart.
