- It is located in the subtropical high-pressure cells.
- It is under the influence of warm ocean currents.
Which of the statements given above is/are correct in this context?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Answer: (a)
Statement 1 is correct: The desert occurs in two broad belts viz. at 20-30° north and south of the Equator along the Tropics of Cancer and Capricorn. At the equator hot air would rise and spread north and south before cooling and it would condense and release its moisture over the tropical zones leading to development of an equatorial zone of low atmospheric pressure. The two tropical zones are at high pressure and nearer to the poles are two low pressure belts of cold. As the denser air sinks towards the ground to the two subtropical high-pressure belts, wind is created which is hot and completely lacking in moisture. This blows across the Middle East, the Sahara, and North America.
Statement 2 is not correct: Eurasian Belt is related to cold currents not warm current.
