Question

Quizplus · Accepted Answer

Volcanism releases carbon dioxide into the atmosphere through the eruption of magma, which contains dissolved carbon dioxide. Photosynthesis, on the other hand, removes carbon dioxide from the atmosphere and converts it into organic matter. The weathering of silicate rocks and burial of organic matter do not directly release carbon dioxide into the atmosphere.
