What is the original source of carbon?

The primary source of carbon/CO2 is outgassing from the Earth’s interior at midocean ridges, hotspot volcanoes, and subduction-related volcanic arcs. Much of the CO2 released at subduction zones is derived from the metamorphism of carbonate rocks subducting with the ocean crust.

What is a good source of carbon?

Dry leaves, corn stalks, straw, bark, and sawdust are also good sources of carbon. Carbon rich sources are often referred to as “browns.” Even newspaper can be shredded and added to compost to supply the carbon.

What are carbon-rich materials?
