Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)
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 ...
Note that Ishtar Terra is located near the negative pole if Venus's rotation is defined as prograde by the right-hand rule. [4] The rotation of the planet is commonly characterized as retrograde in order to correlate its northern hemisphere with Earth's, in which case Ishtar Terra is near the north pole. This is the convention normally used for ...
Evidence of a changing planet can be seen on NASA's website - Global Climate Change: Vital Signs of the Planet. One of the many features of this site is a series of revealing before-and-after ...
On 8 September 2014, NASA reported finding evidence of plate tectonics on Europa, a satellite of Jupiter—the first sign of subduction activity on another world other than Earth. [107] Titan , the largest moon of Saturn , was reported to show tectonic activity in images taken by the Huygens probe , which landed on Titan on January 14, 2005.
This demonstrates the crustal spatial evolution at the Earth's surface dictated by plate tectonics. Earth's crustal evolution involves the formation, destruction and renewal of the rocky outer shell at that planet's surface. The variation in composition within the Earth's crust is much greater than that of other terrestrial planets.
NASA Earth Observatory is an online publishing outlet for NASA which was created in 1999. It is the principal source of satellite imagery and other scientific information pertaining to the climate and the environment which are being provided by NASA for consumption by the general public.
The high, flat, and cold environment of the Antarctic Plateau at Dome C Surface of Antarctic Plateau, at 150E, 77S. The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica that extends over a diameter of about 1,000 kilometres (620 mi), and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station.
