A river can form a gorge by slowly eroding through layers of limestone and other soft rock layers, cutting a deep channel with steep sides. Wind, water and freeze-thaw erosion also helps to erode rock formations on each side to ...
When a river flows over hard rock that overlays softer rock, a waterfall can form. Gorges are formed when waterfalls retreat over time.
