Name a sedimentary rock that will sequester CO₂ in the geosphere.

Question

Quizplus · Accepted Answer

Limestone is the best choice because it contains calcium carbonate, which can react with CO₂ to form stable minerals like calcium sulfate and carbon dioxide, permanently sequestering the CO₂ in the rock. Conglomerate and shale may have small amounts of calcium carbonate, but not enough to effectively sequester CO₂. Rock salt is not a good choice because it does not react with CO₂, and may even release it over time through dissolution.
