In the carbon cycle, carbonate rocks would be most likely to be part of which of earth's "spheres"?

geosphere

Explanation:

Carbonated or limestone rocks are rocks consisting of calcite (calcium carbonate) and / or dolomite (calcium and magnesium carbonate). They may also contain impurities such as organic matter, silicates, phosphates, sulfides, sulfates, oxides and others. The carbonated rocks are formed by the diagenesis of carbonate rich sediments (> 80%), which sediments were deposited essentially by chemical precipitation in aqueous solution. These rocks participate in the carbon cycle, being part of the geosphere.

Carbon cycle is a biogeochemical cycle, that is, a process that ensures the recycling of carbon, enabling this element to interact with the environment and also with living beings. In this cycle we see how carbon moves through the atmosphere, lithosphere, hydrosphere and biosphere.
