Question

Give reasons: People of the Sahara Desert wear heavy robes.

Answer 1

Hint: The Sahara Desert is a desert in Africa. It has an area of 9.2 million kilometers square and it is the largest desert in the world and the third largest cold desert after the Antarctic and Arctic deserts. The word Sahara is Arabic for "desert".

Complete answer:
The temperatures in the Sahara are very high and yet people there wear long heavy robes. This is due to sand storms and heavy winds. Sand and dust storms typically occur when strong winds and dry soils lift large amounts of sand and dust into the atmosphere. Scientists have become aware of the climate, human health, the environment, and many socio-economic implications. Sand and dust storms are common meteorological disasters in dry and semi-arid areas. These are usually caused by thunderstorms, or strong pressure gradients associated with cyclones, resulting in widespread increases in wind speed. It carries dust into the atmosphere from bare, dry soil, hundreds to thousands of kilometers away. About 40% of tropical aerosols are dust particles from wind erosion. These dust particles arise from the arid regions of North Africa, the Arabian Peninsula, Central Asia, and China. Therefore the people in the Sahara Desert wear heavy clothing.

Note: Dust in the air presents serious risks to human health. Particle size is a key determinant of potential danger to human health. Particles larger than 10 micrometers are not breathable, so they can only damage external organs - causing irritation to the skin and eyes, irritation of the eyelids and other health risks.
