Desert - Deserts On Other Planets

Deserts On Other Planets

Mars is the only planet in the solar system on which deserts have been identified. Despite its low surface atmospheric pressure (only 1/100 of that of the Earth), the patterns of atmospheric circulation on Mars have formed a sea of circumpolar sand more than 5 million km² in area, much larger than deserts on Earth.

The Martian deserts principally consist of dunes in the form of half-moon in flat areas near the permanent polar ice caps in the north of the planet. The smaller dune fields occupy the bottom of many of the craters situated at the Martian polar regions.

Famous quotes containing the words planets and/or deserts:

    Marriage is the clue to human life, but there is no marriage apart from the wheeling sun and the nodding earth, from the straying of the planets and the magnificence of the fixed stars.
    —D.H. (David Herbert)

    There are so many intellectual and moral angels battling for rationalism, good citizenship, and pure spirituality; so many and such eminent ones, so very vocal and authoritative! The poor devil in man needs all the support and advocacy he can get. The artist is his natural champion. When an artist deserts to the side of the angels, it is the most odious of treasons.
    Aldous Huxley (1894–1963)
