We investigate the reason for the formation of polygons on Mars
Astronomers now know that on the Red Planet are large in diameter from a hundred to a thousand meters, polygonal formation. How and where they came from - that's the subject of this debate, researchers.
In particular, some people believe that because they are somewhat similar to the geological patterns of our planet, it is likely that formed Martian landmarks around as well. The illustration clearly shows that the Martian map is very similar to normal sea floor. In addition to these polygons there are traces of landslides and erosion of the border.
As for polygons - they are found mostly in the northern plains of the Red Planet. Here, these are the largest objects. With regard to their smaller "brothers" found in other places - their appearance is likely to happen under the influence of thermal contraction - just as in the Earth's permafrost. Scientists from the University of Austin (USA) took the view that talks about the similarity of the Martian maps and terrestrial seabed. On our planet, these polygons are clearly visible in Novrezhskom and the North Sea, ie. E., Where the depth of more than five hundred meters. This suggests to scientists that ancient Mars was covered in the same seas, with the result that it has formed a modern relief.
