What Determines Climate?
Rainfall
Ocean Currents
Prevailing Winds
Elevation
Latitude
MOST IMPORTANTLY - most of the region lies within the tropics

Tropical Climates:Rain Forest
Wettest climate in region
Near the equator
Warm temps.
60 inches of annual rainfall
Canopy trees grow up to 150 ft

Human - Environment Interaction
Rain leaches soil
Can still grow cash crops: banana, pineapples, cocoa, tea, coffee, palms for oil, rubber and cotton
Rain forest threatened by farmers and loggers

Tropical Savannas
Grasslands w/scattered trees
Cover almost 1/2 of Africa
Seasonal rainfall - wetter near equator
Dry air from Sahara carried by harmattan drys moisture
Grass as tall as 15 ft

Serengeti Plains

Dry Climates: Steppe
Semi-arid land between savannas and deserts
Northern steppe is called the Sahel

Sahel
Means “shore” - represents “coast” of the Sahara
Dry land between Senegal and Sudan
Expanding due to decline in rain, climate change, overgrazing and population growth

Desert
South - Namib and Kalahari
North - Sahara
Kenya and Somalia are mostly deserts in the east

Namib Desert

Kalahari
