What is the definition of physical weathering?

the breakdown of rock and sediments into smaller pieces

Explanation:

Physical weathering is when rock is broken down into a smaller rock, or into peices.

Take for example a sea arch.

If you look at the picture, you can see the erosion took away weaker sediment of the rock (middle) and created this arch.

Erosion is when sediment for example is taken from one location and placed into another location. This can be possible by wind water (.ect)

Now that we have an arch, the rock will eventually weaken and crumble into a sea stack. This is weathering.

Therefore, a definition of weathering can be, "the breakdown of rock and sediments into smaller pieces"
