Cliffs are common on [[coast]]s, in [[mountain]]ous areas, [[escarpment]]s and along [[river]]s. Cliffs are usually formed by [[Rock (geology)|rock]] that is resistant to [[erosion]] and [[weathering]]. [[Sedimentary rock]]s most likely to form cliffs include [[sandstone]], [[limestone]], [[chalk]], and [[dolomite]]. [[Igneous rock]]s such as [[granite]] and [[basalt]] also often form cliffs. An [[escarpment]] (or scarp) is a type of cliff, formed by the movement of a [[geologic fault]], or a [[landslide]]. Cliffs are known for forming major geographical features such as [[waterfall]]s. The tallest cliff in the [[solar system]] may be ''[[Verona Rupes]]'', an approximately 20 km (12 mile) high cliff on [[Miranda (moon)|Miranda]], a moon of the planet [[Uranus (planet)|Uranus]]. <ref>{{cite web|url=http://www.guinnessworldrecords.com/content_pages/record.asp?recordid=54819|title=Natural world: the solar system: highest cliffs|publisher=[[Guinness World Records]]|access-date=2009-03-30}}</ref> The [[Ordnance Survey]] distinguishes between cliffs (continuous line along the top edge with projections down the face) and outcrops (continuous lines along lower edge). ==Major cliffs== ===Asia=== '''Above Sea''' *The Cliff of Kurosakitakao, [[Mikurajima]], [[Tokyo prefecture]], [[Japan]] 480 m above [[Pacific Ocean]] '''Above Land''' * [[Nanga Parbat]], [[Pakistan Occupied Kashmir]], 4600 m * [[Great Trango]] Towers, [[Baltoro Muztagh]], [[Northern Areas]], [[Pakistan]], 1340 m * [[Uli Biaho|Uli Biaho Towers]], [[Baltoro Glacier]], [[Northern Areas]], [[Pakistan]] * [[Baintha Brakk]] (The Ogre), [[Panmah Muz
