Nearby geothermal energy vents suggest a location is close to a

A) sunny climate that gets heavy rainfall.

B) spreading tectonic plate boundary.

C) region with karst topography.

D) very large body of water.

The answer is B. The spreading tectonic boundary causes fissures and faults in the crust that could extend close to the mantle. The volcanic activity shows an active region which results to heat from the mantle coming up and heating the water in the crust into steam.
