Aureum Chaos is a rough, collapsed region in the Margaritifer Sinus quadrangle (MC-19) portion of the planet Mars at approximately 4.4° south latitude and 27° west longitude, it is also in the west of Margaritifer Terra. It is 368 km across and was named after a classical albedo feature name.[1] Aureum Chaos is located east of the larger canyon Valles Marineris which include Aurorae Chaos. Other surrounding chaotic terrains are the smaller Arsinoes Chaos to the south, Margaritifer Chaos in the southeast, Aram Chaos to the northeast, Hydraotes Chaos to northwest, Hydaspis Chaos to the north, and further east the larger Iani Chaos. Some 60 km north from the northernmost portion is the equator.


The classic name came from one of the first maps of Mars drawn by Schiaparelli who has been called the "Father of Mars." He called a feature "Aurea Cherso, which translates to the golden peninsula—an ancient name for Malaya.[2] Aureum is the Latin word for gold. In chemistry, the symbol for gold is Au from gold's Latin name.


In many places, the canyons of Aureum Chaos are about 1 km deep—a little more than half the depth of the Grand Canyon. But, Aureum Chaos covers an area about the size of the state of Alabama, almost 20 times larger than the Grand Canyon National Park.

Description


Aureum Chaos is a major canyon system and collapsed area. Large outflow channels on Mars are believed to be caused by catastrophic discharges of ground water.[3] Many of the channels begin in chaotic terrain, where the ground has apparently collapsed. In the collapsed section, blocks of undisturbed material can be seen. The OMEGA experiment on Mars Express discovered clay minerals (phyllosilicates) in a variety places in Aureum Chaos. Clay minerals need water to form, so the area may once have contained large amounts of water.[4] Scientists are interested in determining what parts of Mars contained water because evidence of past or present life may be found there. Aureum Chaos is one more piece of evidence that Mars once had great amounts of water.

Root vegetable, usually orange in color This article is about the cultivated vegetable. For other uses, see Carrot (disambiguation). Carrot Scientific classification Kingdom: Plantae Clade : Angiosperms Clade : Eudicots Clade : Asterids Order: Apiales Family: Apiaceae Genus: Daucus Species: D. carota Subspecies: D. c. subsp. sativus Trinomial name Daucus carota subsp. sativus (Hoffm.) Schübl. & G. Martens The carrot ( Daucus carota subsp. sativus ) is a root vegetable, usually orange in colour, though purple, black, red, white, and yellow cultivars exist. [1] Carrots are a domesticated form of the wild carrot, Daucus carota , native to Europe and southwestern Asia. The plant probably originated in Persia and was originally cultivated for its leaves and seeds. The most commonly eaten part of the plant is the taproot, although the stems and leaves are eaten as well. The domestic carrot ha
