Best Answer

Hydrothermal vents are formed when the earth's crust plates move apart and allow seawater to seep into the cracks. Slowly, the water will heat up as it sinks further into the earth. Minerals from the crust dissolve into the boiling water, and over time, the water will rise and spew out of the opening.

Sea floor spreading develops cracks, some are deep enough so that water (that seeps in) is heated to boiling (and above) and so rises.
