In the area known geologically as "New" Appalachia, especially where there are softer limestone rocks that yield to the constant solution by water and weak acids, numerous caves are a distinctive feature of the physiography.
The physiography and geology of the Mid-Atlantic Ridge have been the subject of much scientific study, as has the geology of the Atlantic as a whole.
The seasonal nature and pattern of Southeast Asia's rainfall, as well as the region's physiography, have strongly affected the development of natural vegetation.
This semi-restriction cannot, in fact, prevent a large amount of dilution by mixing; coastal physiography is the principal factor involved in brine production.
The region's physiography is dominated by a group of large continental islands, however, including New Guinea.
As in much of Cornwall, the physiography alternates between moorlands of igneous-based (granite) intrusives and sedimentary-based valleys, such as the Hayle Valley in the east.
Nevertheless, other factors, such as radiation, moisture, cloudiness, wind, snow and snow blast, ice, and physiography, affect tree lines to various degrees.
In the regional physiography of the conterminous United States, the Interior Lowlands are composed chiefly of the great Central Lowland of the Midwestern states and the Great Plains landform region to the west.
The physiography of Africa is essentially a reflection of the geologic history and geology that is described in the previous section.
The physiography of the area consists of lowlands terminated by the Taungnyo Range in the east.
Its physiography is characterized by low hills, extensive plateaus, and river valleys.
