Africa's Size and Global Position

Africa is the second-largest continent, covering about 30.4 million km² including its islands.
It is separated from Europe by the Mediterranean Sea and from much of Asia by the Red Sea.
Africa joins Asia at the Isthmus of Suez, a 130 km-wide strip crossed by the Suez Canal.
The continent stretches about 8,000 km from Ras ben Sakka in Tunisia (37°21′N) to Cape Agulhas in South Africa (34°51′S).
From west to east it spans roughly 7,400 km, from Cap-Vert (17°31′W) to Ras Hafun in Somalia (51°27′E).

A Continent of 54 Countries

Africa contains 54 recognised countries and 63 political territories in total.
This makes it the continent with the largest number of countries in the world.
Its countries vary enormously in size, population, language, culture and wealth.
The Sinai Peninsula of Egypt, east of the Suez Canal, is usually treated as part of Africa for geopolitical purposes.

Physical Features: Mountains, Lakes and Rivers

Africa's highest mountain is Mount Kilimanjaro.
Its largest lake is Lake Victoria.
The Nile is a major river flowing northwards through the Sahara to the Mediterranean.
The Great Rift Valley is a giant depression formed by the subsidence of whole segments of the Earth's crust.
The Albertine Rift contains the Great Lakes Tanganyika, Kivu, Edward and Albert.
Lake Tanganyika is over 640 km long and is the longest freshwater lake in the world.

Plateaus and Elevation

Africa's average elevation is about 600 m above sea level.
Moderately elevated tablelands are the continent's characteristic feature.
Higher tablelands generally lie to the east and south, with lower land towards the west and north.
The South African plateau is like an inverted saucer, bounded by steep high ground falling to the coast.
The Great Karoo is a dry, barren plateau region, and the Kalahari Desert is even more arid.

The Sahara and the Sahel

The Sahara is a vast desert that separates the Atlas Mountains from the rest of the continent.
The Sahel is the semi-arid transition zone between the Sahara and the wetter savanna to the south.
Desert and semi-desert conditions make water scarcity a major challenge in these regions.

Rainforests and Savanna

Rainforests are found in the wet equatorial regions, mainly around the Congo Basin.
Savanna grasslands cover large areas, especially between the rainforest and the deserts.
These biomes support very different vegetation, wildlife and farming systems.
Coastal plains are often fringed by mangrove swamps and never stretch far inland.

Challenging Stereotypes of Africa

Africa is often wrongly portrayed as a single place of poverty, conflict and wildlife.
In reality it is a continent of contrasts, with modern cities, growing economies and diverse cultures.
It includes deserts, rainforests, mountains, savannas and fertile plateaus.
Its 54 countries have different histories, governments and levels of development.
Avoiding stereotypes means recognising both challenges and opportunities across the continent.

Country Case Study: Kenya

Kenya lies in East Africa and is a useful case study of development and opportunity.
It has a varied landscape including savanna, highlands and the Great Rift Valley.
Its economy relies on agriculture, tourism and services.
Kenya faces challenges such as drought and rapid urban growth.
It also has opportunities in technology, conservation and trade.

Country Case Study: Nigeria

Nigeria is in West Africa and is the continent's most populous country.
It is a major producer of oil, which is central to its economy.
Nigeria has a rapidly growing population and large cities such as Lagos.
It faces challenges including inequality and reliance on oil.
Opportunities include diversifying the economy and a young workforce.
