All of the choices listed — animals, chemicals, water, air, and plants — are indeed agents of weathering. Each of these factors contributes to the breakdown and alteration of rocks and minerals over time.
- **Animals**: Burrowing animals can physically break down soil and rock.
- **Chemicals**: Chemical weathering involves reactions between minerals and environmental agents (like acids, oxygen, and water) that change the mineral composition.
- **Water**: Water can cause both physical weathering (through processes like freeze-thaw cycles) and chemical weathering (by dissolving minerals).
- **Air**: The composition of the atmosphere (including oxygen, carbon dioxide, and moisture) can facilitate chemical reactions that lead to weathering.
- **Plants**: Roots of plants can grow into cracks in rocks, physically breaking them apart, and certain plants can produce acids that chemically weather rocks.
Therefore, the correct answer is **All of the choices**.
