L.I : Explanation of a Sandstorm.


Sandstorms.

A sandstorm is strong dry wind blowing over the desert that raises and carries along clouds of sand or dust. They often appear as solid walls of dust as much as 5,000 feet high.

The strong winds are caused by intense heating from the ground and makes it strong enough to move full sand dunes. Air is unbalanced when heated and this causes mixture with higher winds in the troposphere and lower winds in the atmosphere which creates the tough surface winds.

Sandstorms are most likely to occur in the Sahara Desert or anywhere where rain is unlikely to come. Sandstorms can happen anywhere where the earth is dry. They usually happen on hot summer days under certain atmospheric conditions.

Sandstorms can dry up water, people, plants and anything really that contains water. It can also cause blindness. Thousands of tonnes of sand and dust can be picked up in a sandstorm or duststorm.

If sandstorms happen in a town, it causes health problems, particularly those with lung problems or asthma-related conditions. They also clog up water pipes or air filters. Sometimes it's dumped over the sea and the effect of it is devastating when flood waters dump tonnes of mud into the sea, clogging the gills of sea creatures,  which means wherever the sand or dust is put, it will cause suffocation to animals, plants and even humans.
