Ravine. A ravine is a landform that is narrower than a canyon and is often the product of streambank erosion. Ravines are typically classified as larger in scale than gullies, although smaller than valleys. [1] Ravines may also be called a cleuch, dell, ghout ( Nevis ), gill or ghyll, glen, gorge, kloof ( South Africa ), and chine ( Isle of Wight )

Dry Falls — at the heart of Eastern Washington’s channeled scablands of dry, connected flood channels and deep ravines — is the only Washington or Oregon site on the new heritage sites list.
The result was a number of detailed geological cross-sections of the deep structures below the Alps. When seismic research is combined with insights from gravitational research and mantle tomography the subducting slab of the European plate can be mapped. Tomography also shows some older detached slabs deeper in the mantle.
