The Carbon Cycle

The Slow Carbon Cycle. Through a series of chemical reactions and tectonic activity, carbon takes between 100-200 million years to move between rocks, soil, ocean, and atmosphere in the slow carbon cycle. On average, 10 13 to 10 14 grams (10–100 million metric tons) of carbon move through the slow carbon cycle every year.

T How is carbon GS stored in trees and wood products?

Carbon is cycled through ecosystems in several different forms. It has a tendency to be attracted to oxygen and form gaseous compounds such as carbon dioxide (CO 2) and carbon monoxide (CO) which in high concentrations can be considered air pollutants and play a role in climate change. Carbon dioxide gas can be removed from the atmosphere by

The Science of Biochar

That is simply not the case. When you prevent the biomass from interacting with oxygen you get a biochar that is composed of the carbon that was in the wood. When you let a fire burn in a fireplace much of the carbon goes away and what remains is ash. You buy a small shovel for your fireplace to remove the ashes from a fire.

What is fire? — Science Learning Hub

Gases are made up of molecules (groups of atoms). When these gases are hot enough, the molecules in the gases break apart and fragments of molecules rejoin with oxygen from the air to make new product molecules – water molecules (H 2 O) and carbon dioxide molecules (CO 2) – and other products if burning is not complete.
