Also called “The Great Desert", the Egypt
Sahara desert is the biggest hot desert in the world, laying on
a 9,000,000 square kilometers. Being large as the United State
continent is, the Sahara desert covers parts from the
Mediterranean coasts, of the Northern Africa and some parts that
stretch from the Red Sea. Important parts from Tunisia, Algeria,
Sudan, Mali, Egypt, Chad, Morocco, Libya, Niger and Mauritania
are also covered by the Sahara desert. In its North area, the
Sahara Desert reaches to Egypt (to the Mediterranean Sea) and
covers parts from Libya. The desert borders some shrubs,
woodland and Mediterranean forest from the Africa North, where
the climate is a Mediterranean one, with a rainy season. The
specialist says that the Sahara Northern limit corresponds to
the Northern limit of the cultivation of the Date Palms and to
the southern limit of the Stipa tenacissima, also called the
Esparto, which is a grass. More, the Sahara's Northern limit
corresponds to the threshold of 100 millimeters of precipitation
in a year. But the climate in Sahara is a very dry one, the
precipitations are extremely rare; only 2 centimeters of water
in a year wet the half of Sahara and the most 10 centimeters in
a year wet the rest of the desert. The rainfalls may appear
after very long periods and are in general torrential. In the
desert of Sahara the dust devils and the sand storms can be met,
because of the wind that comes from the North-East. In the
Sahara Desert animals can be met, such as: goats, sand vipers, a
big white antelope called addax, monitor lizards, dromedary
camels and the death stalker, a scorpion that has two toxins in
his venom, generally fatal. There is also some vegetation, like
the olive trees, in oases areas. |
