The answer can vary.
Water and wind are the most common causes of physical weathering. How does this happen? Two potential answers require specific vocab.
-Abrasion

Have you ever caused weathering before? Please tell me one type of weathering you've caused before, and how.
Biological weathering - hiking on mountain day
Chemical weathering - adding acid to the rocks in our first lab
Did we cause weathering and erosion in our second lab or only one? Explain why?
Only erosion. The sediment we used was already broken down, so we did not cause any weathering.
There are a lot!
