Question

how does carbon move during each process? match each process to its best description. gas exchange chemical weathering limestone formation carbon moves from the atmosphere to the hydrosphere or from the hydrosphere to the atmosphere. carbon from the atmosphere interacts with the geosphere and then moves to the hydrosphere via runoff. carbon that has moved from the hydrosphere to the biosphere moves on to the geosphere. submit work it out not feeling ready yet? this can help: the carbon cycle: biosphere processes and interactions (97)

Explanation:

1. For "Carbon moves from the atmosphere to the hydrosphere or from the hydrosphere to the atmosphere" - This describes gas exchange (like CO₂ exchange between air and water bodies).
2. For "Carbon from the atmosphere interacts with the geosphere and then moves to the hydrosphere via runoff" - Chemical weathering involves atmospheric carbon (as CO₂) reacting with rocks (geosphere) and the products moving to hydrosphere via runoff.
3. For "Carbon that has moved from the hydrosphere to the biosphere moves on to the geosphere" - Limestone formation: Organisms in biosphere (like marine organisms) take up carbon from hydrosphere, and when they die, their remains (with carbon) can form limestone in the geosphere.

Answer:

1. gas exchange - Carbon moves from the atmosphere to the hydrosphere or from the hydrosphere to the atmosphere.
2. chemical weathering - Carbon from the atmosphere interacts with the geosphere and then moves to the hydrosphere via runoff.
3. limestone formation - Carbon that has moved from the hydrosphere to the biosphere moves on to the geosphere.
