A map of Earth's biomes

Earth's biomes are closely correlated to the type of climate experienced there. Areas that receive on average large amounts of rainfall (such as the Indonesian islands or central Africa) and warm climates tend to have lush, green forests and wide biodiversity; these biomes are outlined in green on the above map. In contrast, hot, sub-tropical areas with little rainfall (such as northern Africa, central Asia, and west-central Australia) containing sparse vegetation, appear as yellow on the map. Notice the similar arrangements of the biomes for the east coasts of Asia and North America, the symmetry of biome types centered on the Equator through the African continent, and the band of boreal (northern) forests that only exist as large areas in the Northern Hemisphere.
