Fault is a crack or fracture on the earths crust due displacement of rock due to earths movement. Faulting is the process which lead to occurrence of of fault. Tension force lead to formation which lead to formation of normal fault while compression force lead to formation of reverse fault. The following are landforms which can result from faulting process.  

         Block mountains. this is raised highland,  fault bordered block which occur due to raising up of block during faulting. Uplifted or raised block may be tilted to form tilted block or may be horizontal to form Horst. example of block mountains include mountain such as black  forest in German and Ruwenzori in Uganda.

  Rift valley it is major landforms , resulting from the lowering of relatively narrow strip of rock between parallel faults. The most impressive rift valley system in the world is the great rift valley of Africa which extend for over 7600 km from near to Beira in Mozambique  to gulf of Aquaba into Jordan.. rift valley can be formed by both tension and compression forces.

 

Fault steps.these form when a series of parallel faults develop in the region and land between these faults is uplifted at different levels.the land scape forms a series of fault scarp that looks like steps. a good example can be seen at Kijabe west of Nairobi and the Malawi rift

 

Last but not least the faulting process can lead to formation of basins and plateaus. These features result from warping o the earths crust. Uplifted areas due to wraping which have high level or undulating landforms is called plateaus while depressed areas forms basins. Examples of plateaus and basins include lake Victoria basin in east Africa  Deccan plateau and Bolivian plateau

 

To sum up, the faulting process  is one of the process of endogenic geomorphology and is caused by things like tectonic plate movement , earthquake and volcanic eruption
