CO2 is more buoyant than water meaning that when injected into a reservoir it will rise up through the pore spaces in the reservoir rock until it reaches the impermeable cap rock. Good cap rocks such as shales and mudstones are impenetrable to the CO2 and will prevent it from leaking back to the atmosphere. Many natural gas and oil fields around the world have stored both CO2 and natural gas for millions of years in this way.
The porous rocks in oil and gas reservoirs behave like a tight, rigid sponge. A sponge traps air by 'residual trapping' and for this reason to soak a sponge in water it must be squeezed several times to replace the trapped air with water. In a similar fashion when liquid CO2 is injected into a rock formation much of it is trapped within the pore spaces of the rock and this is known as residual trapping.
In the same way that sugar dissolves in tea, CO2 dissolves readily in water. This water containing CO2 is denser than the CO2 free water surrounding it and therefore it will sink to the bottom of the reservoir, trapping the CO2.
When CO2 is dissolved in water it forms a weak acid (carbonic acid) which can dissolve and react with the minerals in the reservoir rock. If the conditions in the reservoir are favourable, new minerals can be formed which coat the inside of microscopic pores in the reservoir rock, and lock away the CO2. However, under most conditions this process is extremely slow and therefore this is the least useful storage mechanism.

photosynthesis, protein, fossil fuels
Two ways were coal and oil.
The energy in a sucrose molecule is stored in the interatomic bonds such as the carbon-oxygen bonds and the oxygen-hydrogen bonds.
Glucose is stored in carbon bonds.
In fats, its mainly stored in carbon-carbon bonds. In carbs, its mainly stored in both carbon-carbon bonds and carbon-oxygen bonds.
In the atmosphere carbon is stored as CO2, methane (CH4), and other organic compounds. in other word, the carbon is stored in a gigatonnes.
stored in carbonate rock.
Carbon cannot be stored in a specific area of the ocean, but the mass percent is 0.0028%
in poo
Carbon dioxide is naturally absorbed (through photosynthesis) and stored in trees and vegetation. It is also absorbed and stored in the oceans.
Dissolved Carbon dioxide
The energy in a glucose molecule is stored in the bonds between the atoms.
Yes, it is.
You think probable to carbon dioxide.
