OASES• Oasis is a place where
water comes to the surface in desert area.
• "oasis" is believed to come from an ancient Egyptian word, "wah," meaning "fertile place in the desert."
• About 75 percent of the Sahara's population live in oases

![Page 26: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/26.jpg)
*The Nile and its tributaries flow though nine countries.
![Page 27: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/27.jpg)
The Nile River• Length: From White Nile Source to
Mouth- 4184 miles, longest river
in the world
• Name: The Nile gets its name from the
Greek word "Nelios", meaning
River Valley.
• Sources: The White Nile: Lake Victoria,
Uganda.
The Blue Nile: Lake Tana,
Ethiopia.
![Page 28: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/28.jpg)
The Nile River flows South to North, where accumulation of sediment forms
a delta.
![Page 29: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/29.jpg)
Everyday Activities on the Nile• Tourism
• Farming
• Fishing• Sometimes you’ll even see crocodiles!
![Page 30: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/30.jpg)
ASWAN DAM on the Nile River
• The Dam was created in 1971
• The Dam wall is 365 feet high
• Created artificial lake- Lake Nasser, which covers 300 miles
![Page 31: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/31.jpg)
Positive effects of Dam• Prevents flooding
• Controls irrigation
• Can plant 3 crops instead of only 1 a year
• Creates Hydroelectric power- supplies Egypt with 40% of its electricity
• Amount of farmland has increased by 2.9 million acres
![Page 32: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/32.jpg)
Negative Effects of Dam
• New layer of fertile soil no longer deposited by annual flood, must use fertilizers–Very expensive–Run off pollutes river, pollution kills
fish• New soil not added to Delta, which
causes erosion
![Page 33: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/33.jpg)
• Water flow has decreased.
–Stagnant water allows disease to increase.
–Salt content has increased, which can ruin crops
–Some experts think weight of Lake Nasser may be producing earthquakes

What am I?
![Page 49: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/49.jpg)
Answer
I am the tip of a camel’s nose and mouth! I am very important to the camel, because my nostrils
can close up completely to keep out the sand. My mouth helps the camel get the most protein
and energy out of poor-quality food in the desert. By swallowing and regurgitating all day, chewing
and chewing and chewing with sideways grinding motions, my special mouth pulverizes food and sucks out every last bit of nutrition.
![Page 50: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/50.jpg)
CAMELS
People have been using camels for over 4,000 years mostly as
pack animals and for transportation. They use their hair for felt, and they are used for their meat and milk as well. They dried manure can even be used as fuel.
![Page 51: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/51.jpg)
• Camels can be gross! They spit, burp, and even worse!
• Camels have adapted to their environment. The secret is in its blood cells (erythrocytes), which can absorb water and expand up to 240% their original size! Camels can drink 40 gallons of water at once and store it in their blood. The humps store 80 lbs. of fat which nourishes the camel in times of scarce food. When the camel uses the fat, the humps shrink. When it eats again, the humps swell up.
![Page 52: North Africa & the middle East Crossroads of Continents Africa EuropeAsia.](https://reader035.fdocuments.us/reader035/viewer/2022062517/56649e7b5503460f94b7c6e0/html5/thumbnails/52.jpg)
• Camels have a third eyelid that goes over the eye like swimming goggles to protect its eyes from the sand!
• The camel's feet are huge and they allow them to walk on the sand like snow shoes.
• Camels live about 40 years and have 1 baby every 12-15 months.
