- Erosional River Landforms
- Waterfalls are found in the Upper Course of a river
- Waterfalls forms when a river flows over an area of hard rock to and area of soft rock.
- The soft rock is eroded more than the hard rock; this creates a 'step' in the river.
- A steep drop is eventually created which creates a waterfall.
- The hard rock eventually erodes and become undercut that makes it unsupported and collapses
- The collapsed rocks are swirled to the bottom where they erode due to corrasion; this create deep plunge pool.
- Overtime, the constant undercutting will cause more collapses. The waterfall will move back up the channel, leaving behind a gorge.

- Interlocking Spurs:
- As rivers erode they create steep sided, V-shapes vallleys
- Rivers end up winding around hils and stick to their paths.
- The hills that interlock with eachother as the river winds around them are called interlocking spurs.
