Most of the sand in deserts came from somewhere else. It was washed there by rivers or streams before the area became a desert.
I have seen that Each grain of sand weights 0.0027 grams One ton is 907,185 grams, That is 335,994,400 grains of sand per ton and there are (aproximately) 700,500,000,000,000,000,000 grains of sand on earth (seven quintillion five quadrillion) from what I could found on the internet, but I don't know for the deserts only <><><> Not all deserts have sand- many are rocky. No one has measured the sand in all the deserts, so the weight is not known.
A deposit of wind-blown sand is called a sand dune. Sand dunes form in deserts, beaches, and other areas where wind is able to transport and deposit sand grains.
That is likely a sand dune, formed by the accumulation of wind-blown sand particles. Sand dunes can be found in deserts, beaches, or coastal areas with strong winds.
I'm guessing you mean sand dunes.
A sand mountain can also be called a sand dune or a sand hill, depending on its size and formation. These formations are created by wind and water erosion, and can be found in deserts, beaches, or coastal areas worldwide.
