Billowing clouds, mountain scene, Limietberg, Western Cape Province, South Africa

Limietberg (Mountain of Limits) is located in the rugged Du Toitskloof mountains, just north of the Boland mountain range. The mountains are riddled with hiking trails, ranging in length from 5 km to 36 km. Most trails are quite challenging due to the steep rocky terrain that is typifies this mountainous region

Road and rock formation in Jemez Valley, New Mexico, USA

Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). Before being deposited, the geological detritus was formed by weathering and erosion from the source area, and then transported to the place of deposition by water, wind, ice, mass movement or glaciers, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from water solution
