	In addition to providing light for Earth, sunlight also acts as a source of [[radiant heat]], warming the Earth. The contribution of sunlight to the Earth is immense, it is a major component of the [[greenhouse effect]], is one of Earth's major [[Earth's energy flows\|energy flows]], as well as being a key factor in [[photosynthesis]]. The [[energy]] stored in [[fossil fuel]]s also originates from the Sun, since fossil fuels originate from dead organisms such as [[algae]] or plankton.
