Most of the sand in deserts came from somewhere else. It was washed there by rivers or streams before the area became a desert.

Sand is made up of microscopic particles, that are many colours. The colour of sand grains ranges from clear to jet black. It just depends on the origin of the original materials.
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.
Hills of windblown sand are called dunes. These are mounds, ridges of sand or other loose sediments commonly found in deserts.
Wood absorbs more heat then sand. This is why at night in deserts it becomes so cold you can die.
