- Rocks interacting with wind and moving water over long periods of time causes weathering
- Weathering means breaking down rocks from a larger whole into smaller pieces by weather / mechanical means
- Hence, interacting with wind and moving water causes the rocks to be broken down from a larger whole into smaller pieces

Therefore, interacting with wind and moving water causes the rocks to be broken down from a larger whole into smaller pieces
Which action most likely causes large rocks to become smaller pieces of rock?
- Rocks interacting with wind and moving water over long periods of time causes weathering 
- Weathering means breaking down rocks from a larger whole into smaller pieces by weather / mechanical means
