The Piedmont Plateau of the Eastern United States between the Appalachian Mountains and the Atlantic Plain is an example. Continental plateaus are bordered on all sides by plains or oceans, forming away from the mountains. An example of a continental plateau is the Antarctic Plateau in East Antarctica.
Platform – A continental area covered by relatively flat or gently tilted, mainly sedimentary strata; Shield – Large stable area of exposed Precambrian crystalline rock; Earth's crust – Earth's outer shell of rock Continental crust – Layer of rock that forms the continents and continental shelves
A flood basalt (or plateau basalt [1]) is the result of a giant volcanic eruption or series of eruptions that covers large stretches of land or the ocean floor with basalt lava. Many flood basalts have been attributed to the onset of a hotspot reaching the surface of the Earth via a mantle plume . [ 2 ]

Continental-continental divergent/constructive boundary Oceanic divergent boundary: mid-ocean ridge (cross-section/cut-away view). In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
The Colorado Plateau is a stable region dating back at least 600 million years. As a relative lowland, it had been a site of deposition for sediments eroded from surrounding mountain regions. [38] Then, during the Laramide Orogeny, the entire plateau was uplifted until about six million years ago. Erosion during and following the uplift removed ...
The Chota Nagpur Plateau is a continental plateau—an extensive area of land thrust above the general land.The plateau is composed of Precambrian rocks (i.e., rocks more than about 540 million years old). The plateau has been formed during the Cenozoic by continental uplift due to tectonic forces. [4]
