Which feedback loop results from increased dissolved CO2?

💡 Explanation

Increased CO2 enhances carbonic acid formation, amplifying the rate of chemical weathering via dissolution; because rock minerals dissolve faster, weathered material increases surface area which further accelerates dissolution, therefore positive feedback occurs, rather than a negative or diminished reaction.
