Nettet25. sep. 2024 · Scientists have long known that seafloor spreading rates impact CO2 levels. Faster spreading plates have more volcanic activity and inject more CO2 into the water, some of which eventually ends up in the atmosphere. They also influence sea levels. “When plates spread rapidly, the entire base of the seafloor rises, as do sea … Nettet19. jul. 2024 · Shortly after the cessation of seafloor spreading, intraplate magmatism affected large areas in the South China Sea (SCS) region.
