question 52

Multiple Choice

Which of the following best describes how geysers erupt?

• A) Water suddenly boils in disconnected voids and cracks above the water table, causing the aquifer to explosively fragment.
• B) With a slight reduction in pressure, water in a saturated, natural conduit suddenly boils, sending a plume of steam and hot water into the air above the vent.
• C) Water slowly boils in a network of vertical cracks above the water table, sending up a plume of steam and hot water.
• D) Water below the water table slowly boils in a vertical crack or natural conduit, causing a plume of condensed water vapor to rise above the vent.
