Question

What type of change is rock

Answer 1

Answer:

Physical Change

Explanation:

Physical changes are those type of changes which affect the physical state of a substance.

For example, the formation of ice is a physical change, which is caused by the freezing of water.

A substance that has undergone physical changes can be brought back into its original form. Taking the example stated above, we can revert the ice back into water by melting the ice.

In short, physical changes only affect the physical features of the substance, but the chemical features remain intact.

Now, how are formation of rocks a physical change?

These rocks are formed by physical changes such as melting, cooling, eroding, compacting, or deforming that are part of the rock cycle.
