The Gobi desert is on the Asian continent. It is approximately 932 mile long and 497 miles wide and covers 500 thousand square miles. The desert basins of the Gobi desert are bounded by the Altai Mountains and the grasslands and the stepps of Mongolia on the North, by the Taklamakan Desert to the west, by the Hexi Corridor and the Tibetan Plateau to the southwest and by the North Chine Plain to the southeast. The Gobi is most notable in History as a part of the great Mongol Empire and as the location of several important points along the Silk Road. The Gobi is a rain shadow desert formed by the Himalayan mountain range which blocks the rain-carrying clouds from the Indian Ocean from reaching the Gobi territory. The temperature here changes rapidly: it can go from +25 degrees F to -30 degrees F just in several days!
