Answer:
Tropical rainforest, also spelled tropical rain forest, luxuriant forest found in wet tropical uplands and lowlands around the Equator. Tropical rainforests, which worldwide make up one of Earth’s largest biomes (major life zones), are dominated by broad- leaved trees that form a dense upper canopy (layer of foliage) and contain a diverse array of vegetation and other life. Contrary to common thinking, not all tropical rainforests occur in places with high, constant rainfall; for example, in the so-called “dry rainforests” of northeastern Australia, the climate is punctuated by a dry season, which reduces the annual precipitation. Tropical rainforests represent the oldest major vegetation type still present on the terrestrial Earth. Like all vegetation, however, that of the rainforest continues to evolve and change, so modern tropical rainforests are not identical with rainforests of the geologic past.
