I typed your question into Google and found this. You could have done the same.
"Physical, or mechanical, weathering happens when rock is broken through the force of another substance on the rock such as ice, running water, wind, rapid heating/cooling, or plant growth. Chemical weathering occurs when reactions between rock and another substance dissolve the rock, causing parts of it to fall away.Apr 5, 2020"
How is chemical weathering different from physical weathering?
