A)CO₂ is removed from the atmosphere.
B)CO₂ is added to the atmosphere.
C)CO₂ is removed by uplift and returned by weathering.
D)They have no net effect on CO₂ .

Question

Quizplus · Accepted Answer

Tectonic uplift can bring rock to the surface, increasing exposure to the atmosphere and allowing for more chemical weathering to occur. Chemical weathering involves the breakdown of rock and the reaction of minerals with atmospheric gases, including carbon dioxide. This process can remove carbon dioxide from the atmosphere and store it as solid compounds in mineral form. Therefore, tectonic uplift and subsequent chemical weathering of rocks can decrease the amount of carbon dioxide in the atmosphere.
