Tropical rainforests are located in hot and wet equatorial regions with heavy rainfall, such as Southeast Asia, Africa, South America, and the Pacific Islands. The vegetation forms a dense canopy with various layers and includes hardwood trees, shrubs, vines, and mosses. These regions experience a hot and humid climate with rainfall throughout the year, supporting the growth of the rich biodiversity found within, including many monkeys, apes, birds, snakes, insects, and large cats.
