Answer:
The journey of a carbon atom from inside a volcano to inside a carbonate rock is as follows:
Step-by-step explanation:
The carbon atom is first released from the volcano during an eruption in the form of carbon dioxide gas.
The carbon dioxide gas then enters the atmosphere and is taken up by plants during photosynthesis, where it is converted into organic carbon.
The organic carbon is then consumed by animals, which release it back into the atmosphere through respiration or it is released through decomposition after the plant or animal dies.
The carbon dioxide gas then dissolves in water and reacts with calcium ions to form calcium carbonate, which eventually settles and forms carbonate rock.
Throughout this journey, the carbon atom undergoes various chemical reactions and changes in form, but ultimately ends up as a component of carbonate rock.
