Its steep fault scarp faces west, and rises from 4000 to 6000 ft.
Einseitige Schollengebirge oder Schollenrandgebirge- Scarp or tilted block mountains.
The scarp or steeply inclined slope; this is necessarily of small extent except in the direction of its length.
Such broken material rolling down a uniform scarp would tend to reduce its steepness by the loss of material in the upper part and by the accumulation of a mound or scree against the loti ii er part of the slope.
But where the side is not a uniform scarp, but made up of a series of ridges and valleys, the tendency will be to distribute the detritus in an irregular manner, directing it away from one place and collecting it in great masses in another, so that in time the land form assumes a new appearance.
The southern and south-western face follows the coast closely up the Persian Gulf from the mouth of the Indus, and is formed farther west by the mountain scarp, which, rising in many points to 10,000 ft., flanks the Tigris and the Mesopotamian plains, and extends along Kurdistan and Armenia nearly to the 40th meridian; beyond which it turns along the Taurus range, and the north - eastern angle of the Mediterranean.
In breadth it is about 30 m., extending between the Satpuras and the southern scarp of the Vindhyas.
One of the scarps or steps is the result of a great fault or displacement of the earth's crust, and is known as the Balcones fault scarp; others are due to erosion and weatherin g of alternate layers of hard and soft rocks lying almost horizontal.
Faulting, probably in Pliocene times, lowered the basaltic plateaus to form the basin of Lough Neagh, leaving the eastern scarp at heights ranging up to 1800 ft.
The glens of Antrim are deep notches cut by seaward-running streams through the basalt scarp, their floors being formed of Triassic or older rocks.
Near the Colorado river the dissected cuesta of the Grand Prairie passes southward, by a change to a more nearly horizontal structure, into the dissected Edwards plateau (to be referred to again as part of the Great Plains), which terminates in a maturely dissected fault scarp, 300 or 400 ft.
They are peculiar in having their altitude dependent on the depth of revived erosion, instead of the amount of faulting, and they are sometimes topographically reversed, in that the revived scarp overlooks a lowland worn on a weak formation in the upheaved fault-block.
The Malwa plateau consists of great undulating plains, separated by flat-topped hills, whose sides are boldly terraced, with here and there a scarp rising above the general level; it is covered with long grass, stunted trees and scrub, which owing to the presence of deciduous plants is of a uniform straw colour, except in the rains.
Taking the Kuren Dagh or Kopet Dagh to form the northern scarp of this plateau east of the Caspian, we find a prolongation of it in the highlands north of the political frontier on the Aras, and even in the Caucasus itself.
(Russian trigonometrical survey), and ending in Khorasan, the great Elburz range presents on its southern, or inward, face a more or less abrupt scarp rising above immense gravel slopes, and reaches in some of its summits a height of nearly 13,000 ft.; and the peak of Demavend, north-west of Teheran, has a height of at least 18,000 ft.
On the east the watershed of the Caspian gradually increases in breadth, the foot of the scarp extending considerably to the north of the south-eastern angle of that sea, three degrees east of which it turns to the south-east, parallel to the axis of the Kopet Dagh.
The Herhaz, though not important in length of course or drainage, also, like the Seafid Rud, breaks through the Elburz range from the inner southern scarp to the north.
The northern part of the western side of the anticline is broken off by a great fault in the valley of the Eden, and the scarp thus formed is rendered more abrupt by the presence of a sheet of intrusive basalt.
The western scarp of the acropolis has been sculptured into a number of sepulchres imitating wooden houses with pillared facades, some of which have pediment reliefs and inscriptions in Lycian.
Along the north-west border of the valley a steep escarpment, known as the Cumberland Scarp, rises to the Cumberland Plateau.
To the Highland Rim Plateau, so named from the scarp formed by its western rim about the Nashville and (farther north) Louisville basins.
The Lower Lias appears at intervals under the scarp of the basaltic plateaus, and contributes, as in Dorsetshire and Devonshire, to the formation of landslips along the coast.
