PLZ HURRY I WILL MARK BRAINLIEST

For the first one, it's B, C, and D. Hydrothermal vents on the seabed, Underwater volcanoes, and the breaking down of rocks.

Second question is C, Fresh water from the glaciers are melting into it.

Explanation:

  For the first answer, I can say that they all relate. Hydrothermal vents on the seabed usually break down rocks with their hot water, same as breaking down rocks and the underwater volcanoes as the broken down rocks they broke escape into the water, therefore making it salty.

  Second answer, the glaciers are frozen up ice, almost fresh water. So if they melted and mixed into the salty ocean, the ratio of salt and ocean will be different, as the amount of water will be cleaner.

I don't know the others, for this is how much I could help. Sorry if I didn't answer in time!!

c. is the answer
