Carbon Cycle Reaches Earth S Lower Mantle 6 Eurekalert The carbon cycle, upon which most living things depend, reaches much deeper into earth than generally supposed all the way to the lower mantle, researchers report. The lithospheric to lower mantle carbon cycle recorded in superdeep diamonds. nature 585 , 234–238 ( 2020) cite this article. the transport of carbon into earth’s mantle is a critical pathway. Seismic wave velocity variations reflect differences in temperature and or composition in the lower mantle (660−2,890 km depth) 7,8,9,10,11, suggesting that the lower mantle, or a part of it, is. Solar radiation affects earth’s interior by changing the redox state of arc magma, influenced by the subduction of carbon rich marine organisms. this discovery links surface climate variations directly to deep earth processes. scientists have long believed that changes in the earth’s interior, such as volcanic eruptions and tectonic plate.
