Question

Quizplus · Accepted Answer

All the statements provided are true. Limestone does contain carbon dioxide in the form of carbonate compounds. Atmospheric CO2 dissolves in seawater and can react with calcium to form limestone, effectively removing CO2 from the atmosphere and ocean. When humans manufacture cement from limestone, the process releases CO2 back into the atmosphere.
