Gaia hypothesis

Lichen and other organisms accelerate the weathering of rocks in the surface, while the decomposition of rocks also happens faster in the soil, thanks to the activity of roots, fungi, bacteria and subterranean animals. One suggested explanation lies in the formation of salt plains throughout Earth’s history.

Its study has, however, generated many new and thought provoking questions. In the biogeochemical processes of the earth, sources and sinks are the movement of elements. It is hypothesized that these are created by bacterial colonies that fix ions and heavy metals during their life processes.
