environment.
3. Chemical and mechanical weathering are both natural processes that will break dow
rocks.
4. Chemical and mechanical weathering has the same processes in breaking down
rocks.
5. Chemical weathering causes changes in rock composition while in mechanical
weathering there is no changing in the physical composition of the rocks
