Describe and draw a diagram of an upper course river landform?
Describe how in waterfalls the water flows over an area or hard rock, followed by an area of softer rock
The softer rock is eroded more than the harder rock, this causes a step.
Eventually, after time a steep drop is created, which is called a waterfall
Hard rock is undercut by erosion and becomes unsupported and collapses
Collapsed rock at the bottom is swirled around and erodes the softer rock by corrasion, this creates a plunge pool
Overtime, more undercutting and erosion will occur which makes the waterfall retreat, leaving behind a steep gorge
Can you draw this diagram?
