The water contained in a geyser system gains energy from the underground
material surrounding it. The water molecules gain kinetic energy and this results
in an increase in the pressure of the water. Eventually the geyser erupts and
expels water into the air above ground.
Which of the following types of energy is the source for the initial energy gain of
the water?
a) electrical
b) magnetic
c) mechanical
d) thermal
