Flanking mountains are generally taller along the east side of the rift (although some of this relief may be Laramide in origin). [1] The thickness of the crust increases to the north beneath the rift, where it may be as much as 5 kilometres (3.1 mi) thicker than it is in the south. The crustal thickness underneath the rift is on average 30 ...
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 ...
Quizlet is a multi-national American company that provides tools for studying and learning. [1] Quizlet was founded in October 2005 by Andrew Sutherland, who at the time was a 15-year old student, [ 2 ] and released to the public in January 2007. [ 3 ]
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 ]
Representative continental flood basalts (also known as traps) and oceanic plateaus, together forming a listing of large igneous provinces: [1] Era Period [ a ]
Mars, Venus, Mercury and other planetary bodies have relatively quasi-uniform crusts unlike that of the Earth which contains both oceanic and continental plates. [1] This unique property reflects the complex series of crustal processes that have taken place throughout the planet's history, including the ongoing process of plate tectonics .
Pangaea or Pangea (/ p æ n ˈ dʒ iː ə / pan-JEE-ə) [1] was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. [2] It assembled from the earlier continental units of Gondwana , Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ...
Satellite image of the Tibetan Plateau between the Himalayan mountains to the south and the Taklamakan Desert to the north. In geology and physical geography, a plateau (/ p l ə ˈ t oʊ, p l æ ˈ t oʊ, ˈ p l æ t oʊ /; French:; pl.: plateaus or plateaux), [1] [2] also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the ...
