Scottish geography, a Carse (the modern form of older Scots kerse) is an area of low-lying, typically alluvial and fertile land occupying certain Scottish river valleys, such as that of the River Forth.
Temperate grasslands, savannas, and shrublands biome, formed of a paradoxical mixture of shallow-rooted calcifuge ("calcium-hating") and deeper-rooted calcicole ("calcium-loving") plants, growing on a thin layer of acidic soil over an alkaline substrate. Chalk heath is intermediate between two much more widespread habitats, chalk grassland and heathland.
Lullington Heath National Nature Reserve.
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 Trust, a Site of Special Scientific Interest. Also see the Friends of Headley Heath. Natural England 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."
inclined plane, channel, or passage through which objects are moved by means of gravity.
geomorphological 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 pass. The height of a summit above its highest col is effectively a measure of a mountain's prominence, an important measure of the independence of its summit. Cols lie on the line of the watershed between two mountains, often on a prominent ridge or arête.

Example of saddle, with map to show contours. The summit of Dun Law is just off the bottom right of the map, the saddle is between that and Glen Ea's Hill.
French word meaning "passage" or "corridor"), is a narrow gully with a steep gradient in a mountainous terrain.
We may not have good examples in Britain and Ireland.
Terraces of Torridonian sandstone - certainly "stairs" but not the hanging valleys of the Wikipedia definition.
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.
