An example of physical weathering is exfoliation. This is when rock layers slowly peel or flake off due to changes in temperature and pressure. Imagine a layer cake, each layer representing a rock layer. As the cake expands and contracts due to changes in temperature, the layers may start to separate and come apart, just like how rock layers can separate due to changes in temperature and pressure. This process can cause large rock formations, like mountains, to erode and break down over time.
