Carbon cycle

carbon cycle  Hank from Crash Course walks us through the carbon cycle: a 'whole bunch of things living and dying, and in the process swapping carbon'  Carbon cycle The carbon cycle is the way carbon is stored and replaced on Earth Some of the main events take hundreds of millions of years, others happen

The carbon cycle comprises a sequence of events that are key to making Earth capable of sustaining life It describes the movement of carbon as it is recycled But carbon in sedimentary rocks, with an average residence time of 400 million years, participates little in global carbon circulation over shorter times The

We need carbon dioxide, water, sugars (carbohydrates ), and oxygen for the basic equations of life that make up the biological carbon cycle: This is the carbon cycle More than half of the carbon dioxide emitted to the atmosphere by human activity has been absorbed by natural carbon reservoirs
