Fault scarp

A fault scarp is the topographicExternal link expression of faultingExternal link attributed to the displacement of the land surface by movement along faults. They are exhibited either by differential movement and subsequent erosionExternal link along an old inactive geologic faultExternal link (a sort of old rupture), or by a movement on a recent active fault. Fault scarps often contain highly fractured rock of both hard and weak consistency. In many cases, bluffs form from the upthrown block and can be very steep. The height of the scarp formation is equal to the vertical displacement along the fault. Active scarps are usually formed by tectonicExternal link displacement, e.g. when an earthquakeExternal link changes the elevation of the ground, and can be caused by any type of fault, including strike-slip faultsExternal link, whose motion is primarily horizontal. This movement is usually episodic, with the height of the bluffs being the result of multiple movements over time. Displacement of around 5 to 10 meters per tectonic event is common.

Fellfield

A fellfield or fell field comprises the environment of a slope, usually alpineExternal link or tundraExternal link, where the dynamics of frostExternal link (freeze and thaw cycles) and of windExternal link give rise to characteristic plant forms in screeExternal link interstices.

Fen

A fen is one of the four main types of wetlandExternal link, and is usually fed by mineral-rich surface water or groundwater. Fens are characterised by their water chemistry, which is neutralExternal link or alkalineExternal link, with relatively high dissolved mineralExternal link levels but few other plant nutrientsExternal link. They are usually dominated by grasses and sedges, and typically have brown mosses in general including Scorpidium or Drepanocladus. Fens frequently have a high diversity of other plant species including carnivorous plants such as PinguiculaExternal link. They may also occur along large lakes and rivers where seasonal changes in water level maintain wet soils with few woody plants. The distribution of individual species of fen plants is often closely connected to water regimes and nutrient concentrations.
