Understanding the ‘deep-carbon cycle’ – Phys.org

New geologic findings about the makeup of the Earth’s mantle are helping scientists better understand long-term climate stability and even how seismic waves move through the planet’s layers.
The research by a team including Case Western Reserve University scientists focused on the “deep carbon cycle,” part of the overall cycle by which carbon moves through the Earth’s various systems.
In simplest terms, the deep carbon cycle involves two steps:

1. Surface carbon, mostly in the form of ca…
