The agents of physical weathering include:
1. **Plants** - They can contribute to physical weathering through root growth, which can crack rocks.
2. **Ice (the cycle of freezing and thawing)** - This is a significant process in physical weathering, as water expands when it freezes, causing rocks to fracture.
3. **Water (liquid)** - While water itself is often associated with chemical weathering, it can also contribute to physical weathering through processes like erosion and hydraulic action.
**Acid** does not contribute to physical weathering; it is primarily associated with chemical weathering processes.
So, the correct answers are:
- Plants
- Ice (the cycle of freezing and thawing)
- Water (liquid)
