Southern Hemisphere Polygonal-Patterned Ground

Southern Hemisphere Polygonal-Patterned Ground

     

This image shows a polygonal pattern found in Mars?s polar regions, similar to the patterning characteristic of Earth?s periglacial environments?the regions where cold climates contribute to the evolution of landforms and landscapes. The patterns found in these environments, such as the arctic of northern Canada, Siberia, and Alaska, often take the form of large polygons, each bounded by either troughs or ridges made up of rock particles different in size from those seen in the interior of the polygon. The polygons found on Earth are usually the result of the repeated freezing and thawing of water. The polygons found in Mars?s polar regions typically occur on crater floors or intercrater plains.
