List and briefly describe four animals that
live in the Sahara?
• Addax- the Sahara's largest indigenous mammal, the
addax travels in small herds throughout the Western
Sahara, Mauritania and Chad. A creature of the dunes,
the addax rarely drinks water. Instead, it sucks moisture
from the desert grasses and bushes that make up its
daily food requirements.
Why is an oasis important?
•
An Oasis is important because an oasis can vary in size from about 2.5
acres for a tiny village to larger farm lands. At its hub is water, often in the
form of natural springs, artesian wells or entire irrigation systems. About 75
percent of the Sahara's population lives in oases, which make up only a tiny
800 square miles of the desert's vast sea of sand and gravel? The date
palm is most characteristic of the vegetation that flourishes there. Other
typical food sources grown in Saharan oases include figs, peaches, citrus
fruits, wheat and barley. The word "oasis" is believed to come from an
ancient Egyptian word, "wash," meaning "fertile place in the desert."
List and describe three topographical
features found in the Sahara.
•
Regs- These plains of sand and black, red or white gravel make up 70 percent
of the Sahara. The Libyan reg stretches for 340,000 square miles; the
Tanezrouft reg, to the west of the Ahaggar Mountains, stretches for 200,000
square miles. The remains of prehistoric seas and rivers, the regs are now
nearly completely waterless. Plant life is sparse; animal life is mostly limited to
rodents.
•
Chotts- Chotts are depressions that fill with salt once moisture from the
Sahara's winter rains evaporates in the spring and summer. Large chotts
occur throughout the northern Sahara. Key scenes from "The English
Patient" and "Star Wars" were filmed in a large chott in western Tunisia
called wChott el Djerid.
•
Wadis- Wadis are temporary water sources located primarily in the
mountains and fed by rainfall. They are home to most of the Sahara's trees
and large bushes.
