which of these is an agent of abrasion?\n\na. high pressures\n\nb. rock pieces\n\nc. acid rain\n\nd. plant roots
Answer
# Brief Explanations:
Abrasion is the process of wearing down by friction. Rock pieces can act as abrasive agents as they rub against other rocks or surfaces. High - pressures are not agents of abrasion but can cause other geological changes. Acid rain is related to chemical weathering. Plant roots are involved in biological weathering mainly through growth pressure, not abrasion.
# Answer:
B. Rock pieces
