Bordering Oceans
Atlantic Ocean and Indian Ocean
Mediterranean Sea
Currents
Eastern side of Africa has cold currents, while western side has warm currents
Ice Cover
very rarely does ice occur
Salinity
[4] Atlantic ocean- High salinity but lower towards equator. (34-37 ppt)
Indian Ocean- A little above average salintity (32-37 ppt)
Mediterranean- High salinity because of high evaporation.
Black Sea & Baltic Sea- Low salinity because large rivers flow into them.
Arabian Sea- High salinity because of high evaporation.
Climate Zones(Top to Bottom)
-Hot, dry summer, warm temperate- Northern coast line(fairly small)
-Hot arid steppe- The Sahara desert (very large)
-Cold arid steppe- The Sahel desert (thin strip under Sahara)
-Equatorial winter dry-
-Equatorial monsoonal-Surrounding Equator- Rainforest
-Equatorial fully humid- On the equator- Rainforest
-Equatorial monsoonal- Surrounding Equator- Rainforest
-Equatorial winter dry-
-Warm temperate, winter dry, warm summer-
-Hot arid steppe- Kalahari desert
-Hot arid desert- Kalahari desert
-Cold arid desert- Kalahari desert
-Warm temperate, warm summer, fully humid- Southern tip of Africa
Climate Controls
-The equator and the Prime Meridian pass through it causing hot temperatures
-The elevation reaches up to 1400 meters which is cooler than sea level
-Has many deserts which cause extreme climate changes daily and receive very little rain
-On the west coast, ocean currents are cooler, while on east coast, ocean currents are warmer
-Almost all of Africa has mild wind currents which make it hotter
-Mostly desert and jungle which means there are pretty extreme climate changes
