True

Front

These rocks were made smooth by wind blowing smaller rock particles across their surface. This is an example of:

Back

abrasion

Front

These limestone gravestones have slowly broken down and turned a blackish color due to the action of: ice wedging, abrasion, acid rain, mechanical weathering

Back

acid rain

Front

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:
