The surface appearance of some regions of Mars is due to how this unit has degraded. It is a major cause of the surface appearance of lobate debris aprons . [ 56 ] The layering of the upper plains mantling unit and other mantling units are believed to be caused by major changes in the planet's climate.
Named after the Roman god of war, it is often referred to as the "Red Planet" [1] [2] because the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere , having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth .
The maps below were produced by the Mars Global Surveyor ' s Mars Orbiter Laser Altimeter; redder colors indicate higher elevations.The maps of the equatorial quadrangles use a Mercator projection, while those of the mid-latitude quadrangles use a Lambert conformal conic projection, and the maps of the polar quadrangles use a polar stereographic projection.
The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It emphasizes the composition, structure, history, and physical processes that shape the planet.
On the basis of that data, scientists have a first-order understanding of the geology and history of the planet. [4] [5] Mercury's surface shows intercrater plains, basins, smooth plains, craters, and tectonic features. Mercury's oldest surface is its intercrater plains, [4] [6] which are present (but much less extensive) on the Moon.
At the bottom of Lake Michigan, an underwater forest, a Russian satellite, more than 1,700 shipwrecks and other discoveries unlock secrets of the past.
