Dust Storms

A scratchy grave

1. Sand storms occur most frequently in arid and semi-arid regions. The areas most affected include the Sahara, the Arabian peninsula, Iran, Pakistan, India and China.

2. Sand Storms occur in the aforementioned areas as a result of natural and man made factors. Natural factors for the presence of sand storms include, dry land, open space where wind can blow and loose top soil such as eroded soil or sandHuman actions that have caused dust storms include poor agricultural and grazing practices such as dry-land farming, which erode and degrade the natural environment and expose the topsoil to high winds.

3. When people inhale the dust they can get silicosis. If silicosis is left untreated it may lead to lung cancer. Dust storms can deplete the soil of the affected area and the dust can destroy crops when blown past them. The dust in the air blocks visibility and stops the movement of planes and cars which disrupts the transportation of goods.

4. In affected areas such as North Africa cities are built with dust storms in mind. The streets are built smaller to reduce the amount of sand blowing through them and house openings are built in an "s" fashion. People will wear scarves over their faces to prevent the inhalation of sand.

Dust storms can rise several thousand feet into the air.
