WebThe physical removal of weathered rock by water, ice, or wind is called erosion. Weathering is a long, slow process, which is why we think rocks last forever. In nature, mechanical and chemical weathering typically occur together. Commonly, fractures in rocks are enlarged slowly by frost action or plant growth (as roots pry into the fractures). chrome pc antigo
