Answer

Brief Explanations:

For Question 14: Volcanic activity can bring minerals from deep - within the Earth to the surface and concentrate them in certain areas through processes like hydrothermal circulation. Desalination is about removing salt from water, siltation is related to sediment deposition, and tectonic movement mainly causes large - scale geological changes rather than direct mineral concentration like volcanic activity. For Question 15: Nuclear energy production through processes like nuclear fission generates radioactive waste that needs proper storage. Oil and coal combustion do not produce radioactive waste in the same sense, and solar is a renewable energy source and does not produce radioactive waste.

Answer:

Question 14: C. Volcanic activity Question 15: C. Nuclear
