Final answer:
Sand formation is a physical change as it involves the breakdown of rocks through weathering and erosion.
Step-by-step explanation:
The formation of sand is a physical change because it involves the breakdown of rocks or minerals into smaller particles without altering their chemical composition. This process occurs through weathering, where rocks are broken apart by wind, water, or temperature changes. Sand grains are made up of minerals such as quartz, feldspar, or calcite, which are physically broken down from larger rock formations through erosion or abrasion.
