rock breaking apart when it falls from a cliff
The correct example of physical weathering is "rock breaking apart when it falls from a cliff".
Physical weathering refers to the breakdown of rocks and minerals into smaller pieces without any chemical changes occurring. In this example, when a rock falls from a cliff, it experiences physical forces such as gravity, impact, and friction, which cause it to break apart into smaller fragments. This is purely a mechanical process, without any chemical reactions or alterations to the composition of the rock.
