Chalk heath

Chalk heath is a rare habitat, in the Temperate grasslands, savannas, and shrublandsExternal link biomeExternal link, formed of a paradoxical mixture of shallow-rooted calcifugeExternal link ("calcium-hating") and deeper-rooted calcicoleExternal link ("calcium-loving") plants, growing on a thin layer of acidicExternal link soil over an alkalineExternal link substrate. Chalk heath is intermediate between two much more widespread habitats, chalk grasslandExternal link and heathlandExternal link.

Lullington Heath National Nature ReserveExternal link.
Natural England describe it: "The slightly acid, fine soil has allowed the development of an intimately mixed chalk and heath plant community. Acid loving heathers and tormentil grow among plants such as thyme, salad burnet and dropwort, which have adapted to the chalk."

Headley Heath owned by the National TrustExternal link, a Site of Special Scientific Interest. Also see the Friends of Headley HeathExternal link. Natural EnglandExternal link say: "Chalk heath occurs on a small area of Headley Heath where the special conditions allow both acid and lime-loving plants to grow side by side."

Chute (gravity)

As a landform a chute, also known as a race, flume, or river canyon, is a steep-sided passage through which water flows rapidly; examples below are of this type of chute. A waterfall, cascade, rapid, cataract, gorge, force, ess, eas, or linn is also this type of chute. A chute can also be a vertical or inclined planeExternal link, channel, or passage through which objects are moved by means of gravityExternal link.

Col

A col in the geographic (as opposed to meteorological) sense is a geomorphologicalExternal link term referring to the lowest point on a mountain ridge between two peaks. It may also be called a saddle, although that usually has a wider meaning and may contain a mountain passExternal link. The height of a summit above its highest col is effectively a measure of a mountain's prominenceExternal link, an important measure of the independence of its summit. Cols lie on the line of the watershedExternal link between two mountainsExternal link, often on a prominent ridge or arêteExternal link.

Couloir

A couloir (a FrenchExternal link word meaning "passage" or "corridor"), is a narrow gullyExternal link with a steep gradient in a mountainous terrain.

Cyclopean Stairs

Cyclopean stairs form as a result of glacial erosion. The term refers to the longitudinal profile of a glaciated valley that has several consecutive hanging valleysExternal link.
Wikipedia pageExternal link
We may not have good examples in Britain and Ireland.

NG8145 : Coire na Poite from the lochan by Jim BartonTerraces of Torridonian sandstone - certainly "stairs" but not the hanging valleys of the Wikipedia definition.

SH6155 : Hanging valley above Llyn Glas with Y Grib Goch in the background by Eric Jones On Snowdon there are some series of hanging valleys. Here there is a hanging valley above Llyn Glas, which is itself in a hanging valley, and Afon Las then falls steeply down to a further valley - and finally into the Llanberis Pass.

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.

Gat (landform)

A gat (GermanExternal link: Seegatt, Seegat or diminutive Gatje) is a water channel that is constantly eroded by currents flowing back and forth, such as tidal currents. It is usually a relatively narrow but deep (up to 30 metres) passage between land masses (islands and peninsulas) or shallow bars in an area of mudflatsExternal link, as well as less deep on lagoon coasts, including those without any tidal rangeExternal link. The name comes from the Low GermanExternal link and DutchExternal link word Gat = gap. The word is incorporated into several proper names, which may or may not be true gats, including the KattegatExternal link, Veerse GatExternal link and Fisherman's GatExternal link.
Wikipedia pageExternal link

The term gat is not used in the British Isles (it does not appear in the Concise Oxford English Dictionary). Looking for the nearest equivalents, we find tidal creeks and tidal races.
