The Richat Structure comprises of Early Paleozoic shakes, around 600 million years of age. Around the middle, rocks impervious to enduring and disintegration (purple and blue-green part) make 100 m high edges and harmless rocks (yellow and dark colored part) structure valleys. These highlights substitute and are concentric.
The Richat Structure was recently thought to have been shaped by shooting star sway or volcanic movement, however field studies have exhibited that nor is right. The ebb and flow believing is that these highlights were formed by uplift and subsequent erosion from wind and water.
the correct answer is history and tradition.
