Question Natural factors, such as wind, rain, etc., help in the formation of soil from rocks. Is this change physical or chemical and why?
The formation of soil from rocks involves both physical and chemical changes. Natural factors like wind, rain and temperature break down rocks into smaller pieces (physical change), while chemical processes, like weathering, also change the minerals in the rocks (chemical change). Both types of changes work together to form soil.
