– The Equator divides Africa almost equally into two parts, with the greater portion lying north of the Equator due to the bulge formed by West Africa
– Bounded between the Tropic of Cancer (23°30’N) in the north and the Tropic of Capricorn (23°30’S) in the south

Terrestrial Boundaries:
– Northern extremity: Al-GhÄ«rān Point (near Cape Blanc), Tunisia
– Southern extremity: Cape Agulhas, South Africa
– Easternmost point: Xaafuun (Hafun) Point, near Cape Guardafui, Somalia
– Westernmost point: Almadi Point (Pointe des Almadies), Cape Verde, Senegal

Maritime Boundaries:
– West: Atlantic Ocean
– North: Mediterranean Sea
– East: Red Sea and Indian Ocean
– South: Meeting point of Atlantic and Indian Oceans

Continental Connections:
– Separated from Europe by the Mediterranean Sea
– Connected to Asia at the northeast extremity by the Isthmus of Suez (163 km wide), which is transected by the Suez Canal
– The Sinai Peninsula of Egypt (east of the Suez Canal) is often considered geopolitically part of Africa
