Sandstorm 
Cause: Sandstorm is caused by strong einds that blw over loose sand particles. The force of the wind makes the sand particles vibrate. The particulates are then eventually carried up before being brought down to ground again.
Effects : Effects of Sandstorms are notorious for their harmful effects, especially towards the environment, health, economy and the live hood of people. Other immediate effects of sandstroms towards the health of people include the worsening of lung functions in people who have asthma. Due of inhalation of large amounts of dust, dust pneumonia could be developed. Disesases such as silicosis could also develop from prolonged exposure to sand. If left untreated, it will eventually lead to asphyxiation and lung cancer. The eyes could also be affected by the particles.Keratoconjunctivitis sicca, or dry eyes, could developwhich could lead to blindness. It has also been reported that exposure to sandstormscould have adverse effects on the circulatory system.
Descriptions: A Sandstorm is described as a natural phenomenon that occurs when a strong wind, such as a gust front, blows fine sand particles and dust from a dry surface. These particles become suspended in the air, causing erosion where they initially were. The wind drops these particles in another place where silt is formed. Sandstorms are fairly common in the Sahara Desert, where warm gusts of wind often send large clouds of dust and debris, especially in arid areas of West Africa during the dry season. The phenomenon known as "Harmattan" usually lasts from January to April.
The Content of a Sandstroms can be : Solid particles, Toxins, Virus or bacteria, And Other subtances as sulfur, heavy metals, carbon monoxide and posibbly pesticides
