Temperature 80% of the continent is in the tropics (between Tropic of Cancer & Tropic of Capricorn) So, climate is generally warm throughout the year.
Africa’s Geography So, because most of Africa is relative flat and warm, our only concern is: Rainfall
Four Major Climate Regions Tropical – Wet Tropical - Wet & Dry DesertTemperate
1. Tropical Wet Climate Region Along the equator Hot & humid all year Avg 80 0 100 inches of rain Rainforests Disadvantages? Leaching- dissolving and washing away of the soil’s nutrients by constant heavy rains.
2. Tropical Wet & Dry Climate Largest climate zone in Africa -covers 1/2 continent Clear wet season and dry season Savanna (grasslands)
3. Deserts Hot & dry all year Sahara (in north), Kalahari (in south) 40% of Africa Desertification: the spreading of desert conditions
Sahara Desert Location: Northern Africa Is the world’s largest hot desert Larger than the United States Temperatures can reach 130 degrees Fahrenheit Windswept rock, gravel and shifting sand dunes Average rainfall per year is less than 10 inches. Few areas have grass which support grazing animals.
Kalahari Desert Kalahari Desert: Southern Africa Not as dry and harsh as the Sahara Grasses and wild melon grow in a few places Antelopes and other animals graze
Oasis Live in desert made possible by oases (desert waterhole, spring)
Geography: Water Use Water is a major concern. It is a commodity It is becoming more scarce It is especially a problem in the areas bordering the Sahara – “the Sahel”
Geography: Water Use Country Domestic (gal/person/day) Total (gal/person/day) Ethiopia 437 Ghana 925 Kenya 1363 South Africa 45265 Africa average 18222 United States 1731328 World average 43481
Geography: Water Use Read the first hand account about water in Africa. Answer: 1. In one complete sentence, summarize the most important main idea of your article. 2. Describe in detail similarities and differences between the water situation in Africa and the United States. 3. Using the ideas in your article and your own critical thinking, what are the larger impacts of scarce water?
BEFORE YOU LEAVE… Using complete sentences, describe the climate of Africa.
