B) the high-temperature vent water causes water molecules to break down into hydrogen and oxygen
C) mixing between the high-temperature vent water and the surrounding low-temperature ocean water creates conditions in which minerals and water will undergo chemical reactions
D) the high pressures existing at the ocean floor cause chemical reactions between minerals and water
