About CORE Blog Contact us A map showing the location of the midpoints of the eastern Asian and eastern North American floras used in this study. This area now forms much of the Interior Plains and the slope of the Appalachians below the mountains proper. [39], Between the Rocky Mountains and the coast ranges is an area dominated by extensional forces. Learn how to create your own. [3] The part of the craton where the basement rock is exposed is called the Canadian Shield. The Cordillera ends in the south in a belt of miogeoclines, including the Sierra Madre Oriental fold and thrust belt, the Mesa Central, and parts of the Sierra Madre del Sur. Canada is not included in the contour maps because of the limited number of climatological stations currently available. North America and South America are named after Italian navigator Amerigo Vespucci. As the basement subsided, sediment accumulated, during the Mesozoic and Cenozoic, forming the modern wedge, containing salt basins. These plates move and interact with one another, driven by convectional forces within the Earth. The Sierra Madre mountain ranges of Mexico are separated by the Mexican Plateau, and transected by the Trans-Mexican Volcanic Belt. [32] Other Mesozoic terranes that accreted onto the continent include the Klamath Mountains, the Sierra Nevada, and the Guerrero super-terrane of western Mexico. [22] Following the Grenville orogeny, mountains eroded, and the sediments from this erosion were deposited below the mountains. The divisions of regional geology are drawn in different ways, but are usually outlined by a common geologic history, geographic vicinity or political boundaries. The lithosphere is divided into a number of tectonic plates. [42] As the Laramide Orogeny ended around 48 million years ago, the accretion of the Siletzia terrane began in the Pacific Northwest.

These local events occurred in the Jurassic, late Cretaceous, and one spanning from the Eocene until the Oligocene. [41], On the West coast of North America, the coast ranges and the coastal plain form the margin, which is partially bounded by the San Andreas Fault, a transform boundary of the Pacific Plate.
