← GeographyWhich ecosystem effect follows increased chemical weathering rates?
A)Oceanic calcium carbonate saturation increase
B)Increased atmospheric carbon dioxide sequestration✓
C)Decreased silicate mineral dissolution rate
D)Reduced riverine sediment transport volume
💡 Explanation
Chemical weathering increases carbon sequestration via mineral reactions; specifically, silicate weathering consumes atmospheric CO2. This Negative Feedback mechanism occurs because dissolving of exposed rock consumes atmospheric CO2, therefore directly addressing the higher atmospheric CO2 concentration rather than related changes.
