Sahara• desert in northern Africa• largest desert in the world at
3,500,000 square miles• from Arabic word Al-Sahra
![Page 11: Africa’s Physical F eatures!](https://reader030.fdocuments.net/reader030/viewer/2022033100/568163a2550346895dd4a3a2/html5/thumbnails/11.jpg)
Kalahari Desert• located in south Africa and covers
Botswana and parts of Namibia and South Africa
• not a “true” desert because it receives 3-10 inches of rain per year
• because of the precipitation can sustain some animal life
![Page 12: Africa’s Physical F eatures!](https://reader030.fdocuments.net/reader030/viewer/2022033100/568163a2550346895dd4a3a2/html5/thumbnails/12.jpg)

Sahel• “Transitional Land”• the transitional land between
desert land and savanna• semi arid land, which is still dry
but gets more rain than the desert
![Page 14: Africa’s Physical F eatures!](https://reader030.fdocuments.net/reader030/viewer/2022033100/568163a2550346895dd4a3a2/html5/thumbnails/14.jpg)

Tropical Rainforest• a forest that receives more water
through precipitation than is loses through evaporation – What are these processes?
• more than 80 inches of rain per year• 1/5 of Africa is rainforest• Africa contains 1 of the 3 major
rainforests in the world.
![Page 17: Africa’s Physical F eatures!](https://reader030.fdocuments.net/reader030/viewer/2022033100/568163a2550346895dd4a3a2/html5/thumbnails/17.jpg)
Savanna• tropical or subtropical grassland
containing scattered trees• receives enough rain to support
drought resistant undergrowth but not enough to support “forest type” vegetation

• The land in between the two rivers is very fertile and a lot of agriculture takes place there.
• Because of this, the area is known as the fertile crescent.
• Some of the earliest civilizations developed here because of its agricultural bounty.

Dead Sea: Lowest Point on Earth
HighestSalt
Content(33%)
2,300’ below sea level

• The saltiest lake is the Dead Sea in Israel and Jordan. It has no outlet and a high evaporation rate, so the salt concentrates even more. It’s so salty (about nine times that of the ocean), it can’t support life.• Its shores are also the lowest dry point on Earth:
about 1,350 feet below sea level (you’re currently about 45 feet above sea level)
• And the salinity (saltiness) allows you to float without effort. Like these guys:
![Page 53: Africa’s Physical F eatures!](https://reader030.fdocuments.net/reader030/viewer/2022033100/568163a2550346895dd4a3a2/html5/thumbnails/53.jpg)
That’s because the water is so much denser than you that it makes you naturally buoyant.
Just don’t get the water in your eyes. It’ll sting.
