Sandstorm

by Maddie

Strong winds blowing over loose soil or sand is what causes sandstorms. Sandstorms can also be called dust storms. They are caused by convection currents.

Sandstorms are able to move entire sand dunes and sometimes able to move entire roads. There are also similar sandstorms in Mars.

A lot of the particles in a dust storm or sandstorm are between 0.08mm and 1mm which also means 0.0032 and 0.04 inches in size.

Sandstorms are limited to within 3m of the ground. They are getting more than 15m high but that is rare. They develop in deserts where sand can be stirred up by wind.

Most sand storms occur during the day when the earth’s surface heats up and spreads at night as it gets cold. Sandstorms are unpredictable, they appear out of nowhere.

Sandstorms can carry huge amounts of sand, so much that the leading edge of one can appear as a solid wall of sand and dust as much as 1525m high.

A sandstorm is so powerful it can even blow away pieces of the Great Wall of China. April is known as sandstorm month in the region. Visibility is often reduced to almost zero.

A sandstorm is a common natural disaster that very often happens. It is so common, a few are going on as we speak..

Sandstorms come with warnings. If the clouds turn dark beige there might be a sandstorm. Sandstorms are so strong and destructive they will blow you 3-5ft away.
