These rocks were made smooth by wind blowing smaller rock particles across their surface. This is an example of: ice wedging, acid rain, abrasion, oxidation

Back

abrasion

Front

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:
- ice wedging
- acid rain
- oxidation
- abrasion
