Block mountains are created when large areas are broken and displaced vertically. The uplifted block is called Horsts and the lowered blocks are called graben.
There are two basic types of block mountains:
- Tilted block mountains have one steep side contrasted by a gentle slope on the other side.
- Lifted block mountains have a flat top and extremely steep slopes.
