A Deep Dive Into the Carbon-Hydrogen Cycle

Earth feels immobile beneath our feet, but deeper down are swirls of solid rock. These slow-moving, vertical loops, called mantle convection, bring hot mantle material up to the surface to grow new seafloor, while dragging the edges of tectonic plates back down into the mantle. As part of this recycling process, mantle convection shuttles carbon dioxide and water from the surface into the mantle, which may encourage melting and help continue this underground circulation.
