question 15 (5 points)
what are the two factors that can cause the volume of water in the ocean to change?

Explanation:

Volcanic vents release minerals from the Earth's interior into the ocean - water, contributing to mineral deposits on the seafloor. Lagoons and coral - reefs are mainly related to biological and shallow - water ecosystems and not significant sources of seafloor mineral deposits. Seafloor spreading is a tectonic process mainly related to the creation of new oceanic crust, not directly a source of mineral deposits like volcanic vents.

Answer:

C. Volcanic vents
