Question

Sand is made of tiny pieces of rock that have been worn down by wind and water. Explain why the formation of sand is a physical change.

Answer 1

This change is only a physical change because the wind and water do not change the chemical make-up of the rock, the weathering is only changing the size nothing else.

Step-by-step explanation:

Physical changes happen when objects or substances experience a change that does not alter their chemical constitution.

Because some of the physical characteristics of the rocks change, but their personalities do not. The shreds of rock are ordered as their sizes and shapes change, but their identities and total section endure the same.

Answer 2

This change is only a physical change because the wind and water do not change the chemical make-up of the rock, the weathering is only changing the size nothing else.
