Suppose Earth were to cool down a little. How would the carbon dioxide cycle tend to restore temperatures to normal?

Question

Quizplus · Accepted Answer

Cooler temperatures would slow down the formation of carbonate minerals in the ocean, which would result in less carbon dioxide being removed from the atmosphere. This would cause the amount of carbon dioxide in the atmosphere to increase, which would strengthen the greenhouse effect and eventually warm up the planet. This process is known as the carbonate-silicate cycle, which acts as a negative feedback mechanism to regulate the Earth's temperature over long timescales.
