Some of it has to do with the hardness of the rock. Sand is normally white or tan because silica is very hard and isn’t broken down easily. Black sands or green sands made of olivine are rare because olivine is softer and the sand gets broken down faster or swept away.
Wind speed.
Ice wedging. In areas without snow, it take longer to break down than areas where water gets frozen in cracks and expands as it cools, breaking up rocks.
Well I’m no meteorologist, but it seems to me the closer you get to the equator the denser the air mass becomes. The farther away it gets from the equator, it obviously gets less dense. I do notice though that the purple are is Greenland, northern Russia and Northern America. Which leads me to believe that it’s more mountain land and it’s density is compared to that of cooler air.
