Intermontane Plateaus
The Intermontane Plateaus is one of eight U.S. Physiographic regions of the physical geography of the contiguous United States, located in the Western United States. The physiographic region is composed of intermontane plateaus and mountain ranges.
Piedmont Plateaus
The surface of the Piedmont Plateau rises in elevation from approximately 200 feet above sea level at its eastern margin to a general base level of 1000 feet above sea level in the west. Individual peaks may rise to over 2000 feet in western parts of the province. Relief varies across the province, a fact which has led to the delineation of two subregions.

The Piedmond Plains is located near the Atlantic ocean and the appachalian plains in the east coast. The Piedmond Plains is located near the Atlantic ocean and the appachalian plains in the east coast.
Piedmont means foot of the mountains.
Plateaus are important as it brings a level of economic value to the country. plateaus are a good source of minerals and are useful for agriculture.impoatnace of plateau(1) Plateaus and Minerals - The plateaus are famous for minerals. The plateau of France, the Deccan plateau of India, Western Australian plateau and Brazilian plateau are very good sources of minerals. I(2) Plateaus and Agriculture - Plateaus are not very useful from the point of view of agriculture. The hard rocks on plateaus cannot form fertile soil but agricultural activities are promoted where lava soils have developed. Lava soil in developed form is found on the terraced slopes of Indonesia. This soil promotes agriculture. It is difficult to dig wells and canals in plateaus. This hampers irrigation.(4) Plateaus and Vegetation - Grass grows on plateaus. Animals are reared on it. The plateaus of Australia, Patagonia and South Africa are well known for the rearing of goats and hippos.

Plateaus can be formed by a number of processes, including, upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers.Magma rises from the mantle causing the ground to swell upward, in this way large, flat areas of rock are uplifted.When plateaus are surrounded by mountains,then Intermontane plateau are formed.eg-The Tibean plateau.

Piedmont is a plateau region located in the eastern United States between the Atlantic Coastal Plain and the main Appalachian Mountains, stretching from New Jersey in the north to central Alabama in the south.
The continent of Asia has five physical divisions:- 1. The Northern Lowlands, made up of the Siberian Plain and the Turan Plain 2. The Central Mountain Belt..a complex system of fold mountains and plateaus.The mountains radiate from the Pamir Knot and have intermontane plateaus and basins in between them.Some of the notable ranges are The Himalayas, the Kunluns, the Hindukush, the Zagros , the Pontic ranges etc.The plateaus of Tibet, Iran and Mongolia are some of the intermontane plateaus. 3. The Southern Plateaus, made of old , hard, crystalline rocks....namely the plateaus of Arabia, the Deccan ,and, the Shan and Yunnan plateaus. 4.The Great River Valleys...made of vast stretches of fertile alluvium...they include the valleys of Tigris-Euphrates, the Indus, The Ganga -Brahmaputra and the Chinese rivers,,,the Huang Ho, the Yangtze and the Sikiang. 5.The Island Festoons of the East..including the Kurile islands, the Japanese Archipelago, Taiwan, the Philippines and Indonesian islands.

Volcanic Plateau - Lava plateaus are formed by highly fluid basaltic lava. Dissected Plateau - Formed usually on a comparatively small scale, by the leveling of terrain by planing and deposition beneath an ice sheet or perhaps, an ice cap. Tibetan Plateau -
The Intermontane Plate was an ancient oceanic tectonic plate that lay on the west coast of North America about 195 million years ago. The Intermontane Plate had a chain of volcanic islands called the Intermontane Islands. The Intermontane Islands had been accumulating as a volcanic chain in the Pacific Ocean since Triassic time, beginning around 245 million years ago. The volcanism records yet another subduction zone. Beneath the far edge of the Intermontane microplate, another plate called the Insular Plate was sinking. This arrangement with two parallel subduction zones is unusual. The modern Philippine Islands are located on the Philippine Mobile Belt, one of the few places on Earth where twin subduction zones exist today. Geologists call the ocean between the Intermontane islands and North America the Slide Mountain Ocean. The name comes from the Slide Mountain Terrane, a region made of rocks from the floor of the ancient ocean.Collision of the Intermontane IslandsOver early Jurassic time, the Intermontane Islands and the Pacific Northwest drew closer together as the continent moved west and the Intermontane Microplate subducted. On the continent, subduction supported a new volcanic arc that again sent intruding granite-type rocks into the ancient continental sediments. Eventually, about 180 million years ago in the middle Jurassic, the last of the microplate subducted, and the Intermontane Islands collided with the Pacific Northwest. The Intermontane Islands were too big to sink beneath the continent. The subduction zone of the Intermontane Plate shut down, ending the volcanic arc. As the Intermontane Belt accreted to the edge of the continent, the subduction zone of the Insular Plate became the active subduction zone along the edge of the continent.
