Question

Groundwater in constricted fractures is heated past its surface boiling temperature by surrounding hot rocks. The superhot liquid expands in volume, reducing its confining pressure, and flashing it into steam.
Which geologic feature matches this description?
A. a geyser
B. a hot spring
C. a mud pot
D. an artesian spring

Answer 1

Answer:

A geyser.

Explanation:

Groundwater sometimes may encounter a magma chamber or a great heat source. As the water gets hot, it reaches its boiling point, however, water cannot evaporate because cold water in the surface, creates a pressure that constricts water, and prevent it from boiling.

Water continues to increase its temperature until it gets superheated and blasts in a quick expansion of volume where the water-vapor its expelled from the vent with great violence.
