- Rainforests are located near the equator; the rainforests require special conditions to be able to prosper, like constant summer with relatively high temperatures, and almost daily precipitation, and these conditions are found around the equator.
- Species found in the rainforests may be used to cure disease; there's thousands of plants/herbs that have been proven to cure lots of diseases for which the pharmaceutical industry hasn't been able to find proper medications.
- Species found in the rainforest decrease each day; because of the destruction of the rainforest on a daily basis, lots of species, both faunal and floral, are being exterminated and thus lost forever from the face of the Earth.
Metamorphism is the addition of heat and/or pressure to existing rocks, which causes them to change physically and/or chemically so that they become a new rock. Metamorphic rocks may change so much that they may not resemble the original rock.
