What are the two largest reservoirs of carbon on Earth?
The oceans are, by far, the largest reservoir of carbon, followed by geological reserves of fossil fuels, the terrestrial surface (plans and soil), and the atmosphere.
What is the largest carbon reservoir on Earth quizlet?
Over geologic time, the calcium carbonate forms limestone, which makes up the largest carbon reservoir on Earth.
What are the main carbon reservoirs on earth?
Most of Earth's carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles.
What are the three largest reservoirs of carbon?
Below are all the major carbon reservoirs on Earth and the approximate amount of carbon they have sequestered in them.
- Deep oceans = 38,400 gigatons.
- Fossil fuels = 4,130 gigatons.
- Terrestrial biosphere = 2,000 gigatons.
- Surface oceans = 1,020 gigatons.
- Atmosphere = 720 gigatons.
- Sediments = 150 gigatons.

Why is the ocean the largest carbon reservoir?
The ocean as a sink for anthropogenic CO The ocean absorbs human-made atmospheric CO2, and this special property of seawater is primarily attributable to carbonation, which, at 10 per cent, represents a significant proportion of the dissolved inorganic carbon in the ocean.
What is carbon reservoir?
Any of the locations within the carbon cycle at which carbon compounds are stored, including the atmosphere, oceans, vegetation and soils, and reservoirs of fossil fuels.
Which carbon reservoir is the smallest?
the atmosphere The smallest reservoir is the atmosphere. The arrows on the diagram indicate fluxes (or movement) of carbon between reservoirs. Each flux arrow has a sink and a source component. A sink is a removal mechanism and takes carbon out of a reservoir and a source is a mechanism that adds carbon to a reservoir.
What are the five major reservoirs of carbon from largest to smallest?

What are the 4 carbon reservoirs?
Understand that Earth's systems can be represented in one way with four major reservoirs: the lithosphere, hydrosphere, biosphere, and the atmosphere.
