Detailed explanation-1: -Weathering can be caused by wind, water, ice, plants, gravity, and changes in temperature.
Detailed explanation-2: -There are three types of weathering, physical, chemical and biological.
Detailed explanation-3: -Physical weathering 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 again it expands and can make the crack even bigger.
Detailed explanation-4: -The major reactions involved in chemical weathering are oxidation, hydrolysis, and carbonation. Oxidation is a reaction with oxygen to form an oxide, hydrolysis is reaction with water, and carbonation is a reaction with CO2 to form a carbonate.
