In sedimentology, a prism is a long, narrow, wedge-shaped sedimentary body. These types of sediments are typically formed during orogenic deformation; for example, the arkose detrital sedimentary rock found in fault troughs. In mineralogy, prismatic is also type of mineral habit (appearance of a crystal). Prismatic minerals have crystals that show a uniform cross-section. Prismatic crystals typically have 3, 4, 6, 8 or 12 faces which are parallel to a crystallographic axis. The apatite group of minerals commonly exhibit elongated hexagonal prisms. An accretionary prism or accretionary wedge is formed from sediments that are accreted onto the non-subducting tectonic plate at a convergent plate boundary. Most of the material in the accretionary wedge consists of marine sediments scraped off from the downgoing slab of oceanic crust but in some cases includes the erosional products of volcanic island arcs formed on the overriding plate. Crystal habit is an overall description of the visible external ...

Traction is the geologic process whereby a current transports larger, heavier rocks by rolling or sliding them along the bottom. Thus, the grains and clasts interact with the substratum during transport. By contrast, saltation, a related sediment transport process, moves grains across the bottom by bouncing or hopping. The actual current carries the sediment load in traction and saltation flows, whereas downslope movement under the force of gravity carries the sediment in gravity flows. These processes contrast with suspension settling, in which there is no current. Traction is where large stones or boulders in the river's load are rolled along by the force of the river.

In Scotland and northern England, a Linn is a geographical water feature, a watercourse that has cut through a shelf of hard rock creating a narrow (usually), steep-sided crevice (fracture) through which it runs. Typically one named after a river or area can have application even for more than one such feature. The photograph of the Linn of Dee illustrates the attributes of a typical 'Linn'. In Gordon (1925) the author describing a walk down Glen Avon in the Cairngorms mentions two Linns on the River Avon - first: A couple of miles below Faindouran Lodge the A'an is spanned by a bridge. Here the river is narrow, with foaming rapids and deep pools where salmon lie of a September day.
