A failed rift valley is known as an aulacogen. It is a three-way continental plate junction in which two of the ridges continue spreading while the third stops. Examples of failed rift valleys are the Rio Grande Rift and the East African Rift.
Most gorges are formed through water erosion. For example, waterfalls erode the rocks they fall over and the falls move gradually back - leaving a gorge behind them. Some gorges are formed as rift valleys; land stretches and a central area drops down - this has formed the Great Rift Valley in Africa and the Great Glen in Scotland.
