What's the difference between a sandstorm and a dust storm?
assistant
The main difference between a sandstorm and a dust storm is that a sandstorm is caused by wind carrying loose sand particles, while a dust storm is caused by dry air moving over large areas of land or water. Sandstorms can cause visibility to be reduced due to the amount of sand in the air, while dust storms are usually more localized and do not affect visibility as much.
