WebThe physical and chemical weathering processes that change parent material into soil include: • Temperature changes — freezing and thawing. • Erosion by water, wind, ice and gravity. • Roots of plants, burrowing animals, insects and microorganisms. • Water relations — wetting and drying. • Changes in chemical composition and volume. WebPhysical weathering occurs when physical processes affect the rock, such as changes in temperature or when the rock is exposed to the effects of wind, rain and waves. Water can get into cracks in a rock and, if it freezes, the ice will expand and push the cracks apart. When the ice melts, more water can get into the larger crack; if it freezes ...
