Natural factors, such as wind, rain, etc., help in the formation of soil from rocks. Is this change physical or chemical and why? Class 7
Answer:
The formation of soil from rocks involves both physical and chemical changes. Natural factors like wind, rain etc. break down rocks into smaller pieces, sand and soil. It is a physical change. Water or chemical present in water can also react with the rocks and cause chemical change in their composition which eventually leads to the formation of soil. It is chemical change. Both types of changes work together to form soil.
