Africa's Physical Features and Climate
Africa's Physical Features
Learning Intention
- To explore how Africa's physical features influence the climate, population, and human activities across the continent.
Introduction to Africa’s Physical Geography
- Africa is the second-largest continent in the world.
- It covers about 30 million square kilometers.
- Home to diverse landscapes, from vast deserts to tropical rainforests.
- Africa's physical features influence the continent's climate, human settlements, and ecosystems.
Major Physical Features
Sahara Desert
- The largest hot desert in the world, spanning most of Northern Africa.
- Area: 9 million km^2
- Mostly made up of sand dunes, rocky plateaus, and dry lakes.
The Nile River
- The longest river in the world: 6,650 kilometers.
- Flows northward from Uganda to Egypt.
- Crucial for agriculture, providing water in an otherwise dry region.
Mount Kilimanjaro
- Located in Tanzania.
- Highest mountain in Africa: 5,895 meters.
- A dormant volcano with a variety of ecosystems from rainforest to alpine meadows.
The Great Rift Valley
- A geological fault line stretching from Syria to Mozambique.
- Known for its deep valleys, volcanoes, and lakes, such as Lake Tanganyika and Lake Victoria.
Plateaus and Highlands
- Africa’s central region is dominated by plateaus and highlands.
- Examples: Ethiopian Highlands and the East African Plateau.
The Atlas Mountains
- Located in North Africa, stretching across Morocco, Algeria, and Tunisia.
Coastal Plains
- Areas of low, flat land along the coastline of Africa.
- Example: West Africa
Climate Zones of Africa
Tropical Rainforest
- Found around the equator.
- The Congo Basin is a vast area of tropical rainforest.
- Known for its high biodiversity, including elephants, gorillas, and chimpanzees.
Desert Climate
- Dominated by dry conditions.
- Examples: Sahara Desert in the north and the Kalahari Desert in the south.
- These areas receive very little rainfall and are extremely hot.
Savanna
- Grasslands with a few scattered trees.
- Mainly found in East and Southern Africa.
- Ideal climate for large herbivores like elephants, giraffes, and zebras.
- Experiences seasonal rains, making it prone to dry seasons.
Mediterranean Climate
- Found along the coast of Northern Africa, including parts of Morocco.
- Experiences mild, wet winters and hot, dry summers.
- Perfect for agriculture like olives and grapes.
The Impact of Physical Features on Human Life
- Rivers like the Nile and Congo support large populations by providing water and fertile soil for farming.
- Deserts like the Sahara limit human settlements, but oases provide vital water sources.
- Mountains and Plateaus often form natural barriers, leading to distinct cultural and regional differences.
- Rainforests and Savannas have rich biodiversity and influence the development of tourism and wildlife conservation efforts.
