VIVAnews - Trench-shaped giant spiral troughs on Mars' north pole that resembles a giant windmills that are no longer mysterious. Scientists have little explanation about one of the characteristics of Mars, called Mare Boreum or giant valleys.
As reported by Space.com, May 26, 2010 edition, the formation of valleys that resembles a giant spiral groove animal snail shell formed through a very long process.
The process of formation of the giant valley just as the formation of small valleys commonly called Chasma Boreale, a pre-existing in the same location.
Process that lasted over a certain period was due to the influence of the sun and wind. Climate on the Red Planet memungkikan also assessed the formation of valleys previously mysterious. Erosion processes in a long time is also one cause of the formation of giant canyons.
Initially, researchers thought that the valleys are older geological phenomena. But they have not been able to prove and can only guess.
Isaac Smith, a planetary scientist at the University of Texas at Austin, said that so far the view that researchers can not be proven. "They are like judge a book by its cover," said Smith.
However, radar technology, opening the eyes of scientists. Radar technology allows scientists to take pictures of two-dimensional (2D). Starting from the cross section and layer in the trench wall, Radar also help track the points geometry of underground structures, to further create three-dimensional image display.
Steep valleys in between the cliffs a total of approximately 1000 kilometers. Reached about two miles thick. Radar research results indicate that the steep valleys were formed long before the emergence of a spiral-shaped shallow trench earlier.
Early research calls, the valleys created by the activity of the giant melting icebergs for long. But the question is, in radar research studies there is no evidence remains of the ice melts.
