Stone polygons is the peri glacial landform feature results from the sorting of surface stones and soil particles into stripes or polygons.
The coordinates that make up a polygon region are determined by actual latitude and longitude values. A point (position) is the fundamental building block of a polygon, and you need at least three points to enclose a region in a polygon.
A peri glacial landform is a structure that is the product of strong frost, frequently in conjunction with perma frost. Periglacial landforms can only be found in regions with cold, essentially nonglacial conditions.
In the arctic and subarctic regions, rivers draining perma frost-covered basins release water and debr is into the sea, forming peri glacial-deltaic landscapes.
