Gaara stands silently, staring into the horizon, as a sudden sand storm overwhelms him, blocking his vision, as the sand hits his eyes. Guarding himself with his bare hands, Gaara stands there, as the storm slowly disappears. A slight smirk on his face appears, as he sees another Gaara, standing near him. It was said that there were 7 people on the entire Earth, who looked alike, but sharing the same name, body and abilities was truly unique. However, his doppleganger was a master of Sand, quite obvious from his confidence and his widespread stories. Maintaining his position, he listens to his shishou, as a smile emerges on his Shisou's face, as he speaks with the same tone as him, albeit more confident, to tell him everything he knew about Sand.
Closing his eyes for a while, Gaara recollects everything he knows and says,
"Sand is a KG, formed by manipulating nearby Earth. The surrounding Earth is crushed and grinded to form finely divided rock and mineral materials, thus creating Sand. It's slightly beige in color and it's thickness varies depending on the amount of chakra put. It's used mostly by shinbois of Sunagakure, but it's primary user is Gaara. Albeit he can create any sand, he keeps specially made sand, in his gourd, which is wore by him on his back like a bag. This increases the speed of his attacks and his versatility with sand, as he could create Sand prisons, sand clones, sand shields, sand clouds and so much more. Due to the number of minerals present in it, it can withstand very powerful attacks, as sand just crumbles and re-forms.
It's quite weak against lightning however, as lightning has pure destructive and piercing force, which can easily break through it. Weak against Water too, as it turns into hard mud when it clashes with Water.
Strong against Wind, as Sand is purely fine particles, which when come in contact with Wind, a sand storm forms. Similarly, when Sand is of a weaker Rank, and Wind of a high rank, Wind carries away the Sand particles, and instead re-directs it at the user himself. Very high ranked Sand is strong against Fire, but when it's of a very weaker rank, it turns into glass, due to the intensity and heat of the flames.
Known users are:

4th Kazekage
