One reason why it's important to collect evidence from many fields is that the methodology of each field can introduce a bias through its measurement methods.
For example, imagine that we find out that our method of sequencing DNA is proven to be wrong - if we collect information from many different fields, then this will not invalidate the evolutionary theory, as evidence from other fields still supports it.
Answer
Hi,
Geochemical cycling is the flow of substances or elements that occurs between reservoirs in Earth’s atmosphere, the water bodies and the lithosphere.
Explanation
A geochemical cycle is normally the path followed by chemical elements in the surface and crust of the Earth. The cycle starts with the crystallization of magma in the lithosphere at the surface or at depth. Weathering and surface alteration follows breaking down igneous rock that will be transported and deposited as sediments. The sediments become lithified and later metamorphosed until melting happens to form new magma.
