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.

Intermontane plateaus are flat, elevated landforms located between mountain ranges. They are typically found in the interior regions of continents. Piedmont plateaus are gently sloping landforms located at the base of a mountain range. They are formed by the accumulation of sediment eroded from the mountains.
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.
The region that is dominated by a dry climate with a topography of plateaus, basins, and ranges is typically found in arid or semi-arid environments such as the American Southwest (e.g., Arizona, Utah, Nevada) or parts of central Asia (e.g., Mongolia). These regions are characterized by low precipitation, high temperatures, and unique geological formations due to tectonic activity and erosion.
A large high area that is generally flat is known as a plateau. Plateaus are elevated landforms with a relatively flat top surface, often surrounded by steep cliffs or escarpments. They can be formed by various geological processes such as tectonic uplift, volcanic activity, or erosion. In the Piedmont region, plateaus are characterized by rolling hills and valleys, located at the base of mountain ranges.
Plateaus are important because they provide flat, elevated areas in various landscapes that are essential for agriculture, transportation, and human settlements. They also serve as watersheds, helping to regulate the flow of rivers and streams. Additionally, plateaus often contain valuable mineral resources and unique ecosystems that support biodiversity.
Mining and quarrying are commonly practiced in plateaus because plateaus often contain valuable mineral deposits such as coal, iron, copper, and limestone. The flat and elevated nature of plateaus also makes it easier to access and extract these resources compared to other geological formations. Additionally, the lack of dense vegetation on plateaus simplifies the process of extracting minerals through mining and quarrying.
