General Geographic Features
Tropical rainforests are the most biologically diverse biome on the planet. They are generally of an equatorial location. This being in between the tropic of Capricorn and the tropic of Cancer. The humid environment and consistent temperature makes this biome one of the most biologically diverse areas in the world. It is subject to constant sunlight throughout the year because of its location (mainly the equator). This means that rainforests are home to some of the worlds largest trees because they can synthesize sugars year round in the near perfect conditions; some reaching over 200 feet. The forest floor however, does not have a lot of plant life because the majority of the light from the sun is blocked by the canopy. The sometimes hilly terrain combined with the amount of rain and their geographic location, has lead to tropical rainforests having some of the largest rivers in the world such as the amazon river. The amazon river has an approximate length of 7 000 km and an average discharge of 209 000 cubic meters, every second.
