Confidence votes 95.7K. A sand tornado is not truly a tornado. It is a phenomenon called a dust devil. Dust devils are whirlwinds that form when a layer of hot air forms just above the ground and rises in a relatively small, rotating column, picking up up dust or sand as it does so. Dust devils are rarely strong enough to cause damage, and are much weaker than tornadoes.
A sandbag is a sack made of burlap or woven polypropylene that is filled with sand or soil and used for such purposes as flood control and military fortification. Sand bags are an excellent choice for the construction of levees, berms, dikes and barricades for erosion control, flood walls, and traffic control. Sandbags may be used during emergencies when rivers threaten to over-flood, or a levee or dike is damaged.
