– Colder temperatures seen in higher elevations
• Therefore, rainfall distinguishes the

• Either side of tropical wet climate to the tropics
• Rainfall varies by season
– Summer – Hot temps & Rainy Season

• Major Feature
– Savanna – most people - grasslands that cover half
the continent. More rain near the equator support
plant and wild life
– Sahel: semi-arid; separates Sahara from savanna
– Unpredictable rainfall makes daily life difficult
– Drought
– Desertification – land turning into deserts; causes
over grazing and drought
Deserts and Desertification
Deserts – 40% of Africa
• Sahara – Means ‘desert’ in Arabic –

– Averages less than .4 inches of rain a year
– Dune 7: the highest sand dune in the world,
383 meters ~ 1200 feet
• Namib

Mediterranean - ~2%
• The Southern Tip and the Northern Coast
• Climate similar to LA
– Hot, Dry Summer
– Cool, Wet Winter
• Fertile soil good for farming
