Hydrothermal vents deep beneath the ocean surface attain temperatures far above 100°C due to
A)higher salt content.
B)reduced salt content.
C)greater pressure.
D)all of the above
E)none of the above

Question

Quizplus · Accepted Answer

The temperature of hydrothermal vents deep beneath the ocean surface is due to greater pressure, which causes the boiling point of water to increase. The high temperatures are not caused by salt content, as higher or reduced salt content does not significantly affect the boiling point of water.
