<span>Mechanical Weathering</span>
BartSMP [9]3 years ago
4 0
The correct answer is physical weathering, also known as mechanical weathering. An example of this would be when water falls into the cracks of a rock. It freezes during cold times and expands in size, which causes the rock to crack even more. When it melts, the crack is bigger and new water goes inside and cracks it even more, and so on and so forth.
