These substances collide with each other on their way and break into small particles. This process continues and soil is formed. During day time, rocks get heated and get expanded. At night, the rocks get cooled and contracted. Continuous expand and contraction causes the breaking of rocks into smaller particles. The two processes explained above are the physical weathering. Rocks break into smaller particles by chemical changes. During rainy season acid rain occurs. The acid decomposes the rocks into smaller particles. Sometimes water enters into the small crevices of the rocks. When the temperature becomes too low, the water freezes and converts into ice. The ic...
