The Correct Answer and Explanation is:
The other options illustrate different interactions between Earth’s spheres. Image A shows a power plant releasing emissions, representing a transition from the anthroposphere (human systems) to the atmosphere (the sphere of gases). Image B shows a forest fire releasing carbon dioxide from burning trees. This is a transition from the biosphere (the trees) to the atmosphere (the carbon dioxide gas). Image D shows two processes. Marine photosynthesis is an interaction within the biosphere and hydrosphere (water). The sinking of dead animals shows a transition from the biosphere to the ocean floor sediments, which are part of the geosphere. However, image C provides a more direct and clearly labeled illustration of organic life becoming integrated into the solid landmass, making it the best answer.
