A long eastern trough has steep escarpments, chains of deep lakes, and nearby volcanoes where the crust is pulling apart. Which landform region is described?

A broad, low, bowl-shaped interior drained by the Congo River is covered largely by equatorial rain forest. Which landform region is this?

Rugged uplands in the Horn of Africa stand high above surrounding lowlands and feed the Blue Nile. What landform region is described?

A steep mountain escarpment along Lesotho and eastern South Africa marks the edge of the southern African plateau. Which landform is it?

An elevated savanna plateau around Kenya and Tanzania is broken by volcanic peaks and rift valleys. Which landform region is described?

A sandy, semiarid basin covers much of Botswana and neighboring areas, with dry grassland and seasonal pans. What is it?

A highland area in Guinea sends streams toward the Niger, Senegal, and Gambia river systems. Which landform region is described?

This river rises in the highlands of Guinea, arcs through the Sahel, then turns south to a large delta on the Gulf of Guinea. Which river is it?

This river drains the equatorial basin of central Africa, crosses the Equator twice, and reaches the Atlantic Ocean. Which river is it?

White Nile water from the Lake Victoria region and Blue Nile water from Ethiopia join before the river flows north to the Mediterranean. Which river is it?

This river rises in south-central Africa, flows east across Zambia, drops at Victoria Falls, and enters the Indian Ocean in Mozambique. Which river is it?

This river begins near the Highveld, forms parts of southern Africa's borders, and flows east through Mozambique to the Indian Ocean. Which river is it?

This river starts in the Lesotho highlands, crosses dry western South Africa, and reaches the Atlantic along the Namibia border. Which river is it?

Many Sub-Saharan rivers drop over falls and rapids close to the coast, limiting navigation from the ocean to the interior. What physical feature causes this pattern?

Lake Tanganyika and Lake Malawi are long, narrow, and very deep in steep-sided troughs. What process made that shape?

Southwestern Africa is arid along the Atlantic even where moist ocean air seems nearby. What helps create the Namib Desert?

The Congo Basin stays hot and wet through much of the year and supports dense equatorial rain forest. What best explains that physical pattern?

Mount Kilimanjaro and other East African volcanoes stand near a major rift zone. Why are volcanoes common there?

In the Okavango, a river spreads into wetlands and evaporates instead of reaching the sea. What physical setting allows this inland delta?

Lake Victoria is broad and relatively shallow compared with deep rift lakes nearby. What accounts for the difference?

One eastern lake has the largest surface area of any African lake, spreading widely across a shallow plateau basin. Which lake is it?

One rift lake is Africa's deepest freshwater lake and is much deeper than broad Lake Victoria. Which lake is it?

A long, deep lake at the southern end of the East African Rift borders three countries, including Mozambique and Tanzania, and drains south through the Shire River. Which lake is it?

This central African drainage basin is the world's second-largest river basin after the Amazon and straddles the Equator. Which basin is it?

A shallow, endorheic lake in the Sahel has changed greatly in surface area with rainfall and drought. Which lake is it?

Africa's coast is comparatively smooth, with few deep bays or sheltered inlets. What does that coastline mean for settlement and trade?

Because Africa has few large peninsulas and offshore seas for its size, its shoreline is short relative to its area. What geographic result follows?

On many coasts, narrow plains rise quickly to an escarpment or plateau. What does that mean for routes from ports to the interior?

Several West African coasts have surf beaches, lagoons, and sand bars instead of deep, protected bays. What does that mean for harbor development?

Madagascar and a few island groups stand out because much of Sub-Saharan Africa has few large offshore islands. What does that coastline pattern mean?
