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?

Choose one:A. a geyserB. a hot springC. a mud potD. an artesian spring

Option (A)

Explanation:

Geysers are distinctive geological features that are formed in the region, where the water below the surface of the earth is heated due to the high temperature or the heat energy radiated into the surface of the earth from the core. These are known as geothermal energy. This heats the water so much that it exceeds the surface boiling temperature and eventually rises up towards the surface.

These are areas of volcanisms that lead to the eruption of hot water forming steams, through the vents.

Thus, the correct answer is option (A).
