Flashcards in 1.3 The Carbon Cycle Deck (5)
What is the primary source of carbon on earth?
What are the 8 main flows/transfers of carbon?
What is carbon sequestration?
Capturing CO2 from the atmosphere and putting it into long term storage
What is geologic sequestration?
CO2 is captured at power plants or industries and then injected in liquid form to underground stores. Could be depleted oil and gas reservoirs, thin uneconomic coal seams, deep salt formations and the deep ocean.
The ocean is capable of absorbing much more additional carbon than terrestrial systems, because of its size
Advantage is that by the time the carbon reaches the sea bed after thousands of years, it will be part of the natural geological cycle
