Areas that receive plentiful rainfall and are covered by thick forests?

• A. Rainforests
• B. Deserts
• C. Grasslands
• D. Tundras

Answer: (A)

Rainforests are places where rainfall is abundant and warmth is year-round, allowing a dense, multi-layered forest to thrive. The constant moisture and warm temperatures fuel rapid growth, producing tall trees, vines, and a closed canopy that creates a humid, shaded understory. You’ll find this lush, thick forest in tropical regions near the equator, like the Amazon, the Congo Basin, and parts of Southeast Asia. This combination of heavy rainfall and dense vegetation is exactly what defines rainforest environments.

Deserts, by contrast, receive very little rain and have sparse plant life. Grasslands get more rainfall than deserts but not enough to sustain thick, continuous forest cover, so they’re dominated by grasses with only scattered trees. Tundras are cold and have permafrost, with a short growing season and mainly low-lying vegetation rather than tall, dense forests.
