have you heard of sandstorm? It is a natural disaster.It often happens in the desert.A sandstorm is like snowstorm.They both cause a lot of trouble for people.In sandstorms,the wind carries the sand.Sandstorms are different from other disasters.They come with a warning but other disasters come without any warnings.So when you see that clouds have a dark colour,it means there is going to be a sandstorm.
If there is no rain for a long time,sandstorms may happen.When there are sandstorms in cities,there will be no planes in the sky.It would be dangerous for a plane because he cannot see clearly.There would also be more traffic accidents in the street.The sky is gray and people cannot see very far.
There are many desertas in Africa and Asia.Sandstorms often happen in these places.People can stop sandstorms by planting trees.
