The features formed by river erosion include:
- **Gullies**: These are steep, narrow channels that form when water carries soil away, typically from runoff.
- **Meanders**: These are curves or bends in a river that form as water erodes the bank on one side and deposits sediment on the other.
- **Oxbow lakes**: These form when a meander from a river is cut off, creating a crescent-shaped lake.
- **Rills**: Small channels formed by surface runoff that can lead to larger erosion features over time.
- **Streams**: While streams themselves are not a feature formed by erosion, they often contribute to erosion as they flow and can create other features through their movement.
- **Waterfalls**: These occur when a river flows over a steep drop or cliff, often resulting in significant erosion at the base.
Given the context of your question, the correct answers for features specifically formed by river erosion are **gullies, meanders, oxbow lakes, rills, and waterfalls**. Streams are part of the process but not specifically a feature formed solely by erosion.
