Which two factors are critical to the existence of the carbon dioxide (CO₂)cycle on Earth?

Question

Quizplus · Accepted Answer

Plate tectonics are important for the carbon cycle as they help release carbon dioxide from rocks during volcanic activity. Liquid water oceans help dissolve carbon dioxide from the atmosphere and store it in the form of bicarbonate ions. Together, these two factors contribute to the existence of the carbon dioxide cycle on Earth. Life is not essential for the carbon cycle, as it can exist without biological activity. Atmospheric oxygen and active tectonics are not critical factors for the carbon cycle.
