Question

the composition of the atmosphere can change due to all of the following except
volcanic activities
human activities.
earths rotation
biological activities (plants and animals)

Explanation:

Volcanic activities release gases like sulfur dioxide. Human activities (e.g., burning fossil fuels) add carbon dioxide. Biological activities (e.g., photosynthesis by plants, respiration by animals) affect oxygen and carbon dioxide levels. Earth's rotation mainly affects day - night cycle and wind patterns, not the chemical composition of the atmosphere.

Answer:

C. Earth's rotation
