What are the main monuments on Mars?

Mars is a desert planet covered with iron oxide (rust) that gives it its red color and nickname the "red planet". The planet has a weak atmosphere of mainly carbon dioxide, only 0.6% as strong as Earth. The atmosphere on Mars has pressure similar to the ground at an altitude of 35 km (22 miles). The surface temperature ranges from -140 ° C (-220 ° F) during winter to a maximum of 20 ° C (68 ° F) in summer. Like all planets without water bodies for modulating their temperature, Mars are experiencing larger thermal extremes than Earth.

Although there is evidence that liquid water has flowed on Mars surface in small quantities in the last few years, it is probably a rare occurrence, because most h _{2 sublimates (passing directly from the solid to the gas) rather than through a liquid stage. Some resistant microbes from the country would be able to survive in the Martian environment and may have been introduced by Mars Rovers who have been sent there in the last few years.}

Mars has the highest mountain and volcano in the solar system, Olympus Mons (height: 27 kilometers, 16.7 million, 88 580 ft) and the largest slot in the solar system, Valles Marineris (4,000 km (2,500 mi) Dlouhý, 200 km (125 Mi) wide). Like the Moon, Mars is a mixture of lower plains covered with lava flows and ancient highlands with numerous craters. Unlike the Moon, the lava plains are lighter portions, covered with iron dust, while the Highlands are darker.

The origin of Olympus Mons and Valles Marineris is quite interesting. Olympus Mons is a volcano of shields such as Mauna Kea in Hawaii, which is actually the highest mountain of the country if you measure from the bottom of the ocean. This means that it is much wider than it is tall, and is the result of many eruptions for a long time. Mars lacks tectonic albums, so the volcanic hot vice -science puts the lava over the same bark, leading to volcanoes of this size. Some of this volcanic activity took place recentlyD for two million years based on the analysis of the frequency of impact craters on the chilled magma flows.

Marineris Valles is so great that it extends over one fifth of the entire Martian equator. If it overlap on the countries, Valles Marineris would extend to the United States, from San Francisco to New York. The canyon is so large, scientists had historically problems in determining its origin. Initially, some thought the valley could have been carved by an asteroid of the size of a small planet that scratched the Martian surface, but never had a full impact. Most scientists today agree that Scarp is a tectonic feature caused by the stretching and cooling of the Martian cortex due to subsurface volcanism.
