Question

which process causes minerals to become concentrated in certain areas? a) desalination b) erosion c) siltation d) volcanic activity question 14 (5 points) whats the greenhouse effect? a) human - caused global warming b) the regulation of atmospheric and surface temperatures c) the release of extra moisture from water vapor

Explanation:

For the first question, volcanic activity can bring minerals from deep - within the Earth to certain areas and concentrate them. Desalination is about removing salt from water, erosion is the movement of soil and rock by natural forces, and siltation is the deposition of silt. For the second question, the greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, regulating atmospheric and surface temperatures. Human - caused global warming is a consequence of the enhanced greenhouse effect, and the release of extra moisture from water vapor is not the definition of the greenhouse effect.

Answer:

1. D. Volcanic activity
2. B. The regulation of atmospheric and surface temperatures
