Which term names a region with very low rainfall where vegetation is sparse?

• A. Rainforest
• B. Tundra
• C. Desert
• D. Savanna

Answer: (C)

Desert landscapes are defined by very low rainfall. When annual precipitation is extremely scarce, soils stay dry and water is hard to come by, so only plants with special adaptations can survive and vegetation remains sparse. Deserts can be hot, like the Sahara, or cold, like parts of Antarctica, but aridity is the key feature. In contrast, a rainforest has abundant rainfall and dense vegetation; tundra has a cold climate with a short growing season; and savanna has seasonal rains that produce grasses with scattered trees, not sparse plant life.
