The definition of "a geothermal feature of the Earth where an opening in the surface contains superheated water" best fits which science term?

A geyser is a geothermal feature of the Earth where an opening in the surface contains superheated water. This definition accurately describes a geyser, which is a natural phenomenon where water is heated by geothermal energy and periodically erupts, shooting hot water and steam into the air. A barometer is an instrument used to measure atmospheric pressure, carcinogens are substances that can cause cancer, and a prism is a transparent object that refracts light. None of these terms match the given definition, making geyser the correct answer.
