Transitions, interactions or shifts in our geological and biological history include processes such as mineralization, hydration, development of atmosphere and oxidation. There is beauty in the truths of the natural world. Photosynthesis from bacteria created the oxidation event allowing for the rust of iron rich rock, which in turn colored our world. This is one of three images in a series. I did a lot of reading and research and identified some major events that led to the creation of color on earth. Those events are broken down into three main shifts: Shift 1 represents the mineralization process and outgassing from lava, that contributed to building the atmosphere, the second, Shift 2 represents the building of the atmosphere and the hydration of the earth/oceans from a moisture laden atmosphere and the third Shift, represented here, reflects the "oxidation event" attributed to photosynthesis creating the oxygen rich environment that "rusted" the earth contributing to the colors we have today. So in this piece you see the cyanobacteria and algae and the rust/iron rich rock.
