A catena forms when the climate, including precipitation and evaporation, is the same for the whole slope, and when sufficient time has passed for equilibrium to be reached between the processes that bring materials in to a facet and the processes that take materials away. The result is a predictable sequence of soil facets. [10]
Butte – Isolated hill with steep, often vertical sides and a small, relatively flat top; Canyon – Deep chasm between cliffs; Cliff – Tall, near vertical rock face; Col – Lowest point on a mountain ridge between two peaks; Cuesta – Hill or ridge with a gentle slope on one side and a steep slope on the other
Drumlin – an elongated whale-shaped hill formed by glacial action. Butte – an isolated hill with steep sides and a small flat top, formed by weathering. Kuppe – a rounded hill or low mountain, typical of Central Europe. Tor – a rock formation found on a hilltop; also used to refer to the hill, especially in South West England and the ...
A tor in Altai Krai, southern Siberia. A tor, which is also known by geomorphologists as either a castle koppie or kopje, is a large, free-standing rock outcrop that rises abruptly from the surrounding smooth and gentle slopes of a rounded hill summit or ridge crest.
Slopes that are convex upslope and concave downslope and have no free face were held by King to be a form that became common in the late Tertiary. King argued that this was the result of more slowly acting surface wash caused by carpets of grass which in turn would have resulted in relatively more soil creep. [3] [4]
Flow direction here was at time of formation from west to east (left to right on picture). A drumlin , from the Irish word droimnín ("little ridge"), first recorded in 1833, in the classical sense is an elongated hill in the shape of an inverted spoon or half-buried egg [ 1 ] [ 2 ] formed by glacial ice acting on underlying unconsolidated till ...
A homoclinal ridge or strike ridge is a hill or ridge with a moderate, generally between 10° and 30°, sloping backslope. Its backslope is a dip slope, that conforms with the dip of a resistant stratum or strata, called caprock.
In the diagram top right, the saddle is comparable to the leftmost drawn type. A saddle is the lowest area between two highlands ( prominences or peaks) which has two wings which span the divide (the line between the two prominences) by crossing the divide at an angle, and, so is concurrently the local highpoint of the land surface which falls ...
