Constant moisture. Rainforests are called rain forests because they get tons of rain year-round, making them the wettest places on Earth. This constant moisture is what makes them so lush and alive.

Layered canopy. The trees grow so thick and tall that their branches and leaves form a closed umbrella above the forest floor, blocking out most sunlight. This layered structure creates different habitats at different heights.

Plants everywhere. Rainforests are home to epiphytes, which are plants that grow on other trees without hurting them, and lianas, which are long woody vines that climb up trees. These plants thrive because of all the moisture in the air.

No wildfire zone. Because rainforests are so wet, fires almost never happen naturally. This allows the forest to keep growing and changing slowly over thousands of years.

Two main types. Tropical rainforests are near the equator where it's hot and humid all year, while temperate rainforests are in cooler places like the Pacific Northwest. Both types are incredibly diverse and important.
