atmosphere and hydrosphere are involved in the carbon cycle that is fueled by the solubility pump

In oceanic biogeochemistry, the solubility pump is a physico-chemical process that transports carbon (as inorganic carbon) from the ocean's surface to its interior.

The ocean "solubility pump" removes atmospheric carbon dioxide as air mixes with and dissolves into the upper ocean. Carbon dioxide is more soluble in cold water, so at high latitudes where surface cooling occurs, carbon dioxide laden water sinks to the deep ocean and becomes part of the deep ocean circulation "conveyor belt", where it stays for hundreds of years. Eventually mixing brings the water back to the surface at the opposite end of the conveyor belt in regions distant from where the carbon dioxide was first absorbed, e.g., the tropics. In the tropical regions, warm waters cannot retain as much carbon dioxide and carbon dioxide is transferred back into the atmosphere.

so atmosphere and hydrosphere are involved in the carbon cycle that is fueled by the solubility pump

1. Construct a model that has a central carbon atom with four different colored spheres attached to it, representing four different atoms or groups. Fill in the line-and-wedge drawing below to represent this model and answer the following question: (a) Does the model have a plane of symmetry? The central carbon atom is said to be a chirality center. Most molecules of nature are chiral. The word “chiral” is derived from the Greek word, cheir and means “handed.” Chiral molecules...
