Example 1

The Sahara Desert, the largest desert in the world, is located in the northern Africa and occupied approximately 10 percent of the African continent.  From the Atlantic Ocean in the west, the Sahara Desert stretches across Africa to the Red Sea and down to the highlands of Ethiopia, covering an area of 9,100 000 square kilometres, 1,610 kilometres wide and about 5,150 kilometres long from east to west.

The Sahara is one of the hottest region in the world, with arid land, and dry climate. In the hottest months, temperatures can rise over 50°c, and temperatures can fall below freezing point in winter. A single daily variation is from -0,5° c to 37,5°c. The Sahara is also extreme windy, which creates dust devils which can make the temperatures even hotter.

The surface of the desert ranges from large areas of sand dunes to stone plateaus, gravel plains, dry valleys and salt flats. People can find some tablelands with an average elevation from 400 to 500 metres. Very few forms of animal and vegetable life can be seen in the Sahara. Plants and animals of the Sahara are more threatened by desiccation than the fauna and flora in other parts. The main trees can be seen are cactus, date palm and a form of Acacia.

In the vast area of sand and wind, people can find some species of mammals such as desert antelopes, gazelle, fox and jackal. Besides, there are some species of birds and reptiles.

The Sahara Desert is not well-protected. Unless people take appropriate measures to preserve, the flora and fauna of the Sahara is critically threatened with extinction.

The Sonoran Desert is a North American desert which expands part of the United States - Mexico border and covers large parts of Arizona and California and the Mexican states. It is one of the largest and hottest deserts in North America, with an area of 311,000 km2.

The Sonoran Desert contains a variety of unique plants and animals. The desert includes 60 mammal species, 350 bird species, 20 amphibian species, more than 100 reptile species, 30 native fish species, and more than 2000 native plant species. Despite the common stereotype that it does not rain in deserts, the Sonoran Desert is considered the wettest desert in the world, receiving 3 to 15 inches per year (depending on location in the desert).

Many plants not only survive the harsh conditions of the Sonoran Desert, but they actually thrive. Many have evolved to have specialized adaptations to the desert climate. The Sonoran Desert includes such plant from the agave family, palm family, cactus family, legume family, and many others. This desert is the only place in the world where the famous saguaro cactus grows in the wild.

The desert is home to seventeen aboriginal American cultures. The largest city in the Sonoran Desert is Phoenix, Arizona, the USA. This metropolitan area in central Arizona is one of the fastest-growing metropolitan areas in the United States, with a population of 4 million. In the North Phoenix area, desert is losing ground to development at a rate of approximately 4,000 m2 per hour. The next largest cities are Tucson, in southern Arizona, with a metro area population of around 900,000, and Mexicali, Baja California, Mexico, whose municipality also has a population of around 900,000.
