Look at the figure below.What problem might occur during the long-term operation of a geothermal power plant?
A) The groundwater flowing to the geothermal well would dissolve rock, creating solution features within the bedrock.
B) The groundwater flowing to the geothermal well would deposit-out (precipitate) minerals, decrease the permeability of the rock formation, and decrease the flow of water to the well.
C) The groundwater flowing to the geothermal well would fill the well with placer deposits.
D) The groundwater available to flow to the geothermal well would eventually be used up, and the geothermal well would cease providing hot water to the plant

Quizplus · Accepted Answer

Over long-term operation, the groundwater flowing to the geothermal well can deposit minerals within the rock formation, decreasing permeability and flow of water to the well. This can lead to decreased efficiency of the power plant and ultimately, reduced power generation capacity. The other choices (A, C, and D) are not relevant to the long-term operation of the geothermal power plant.
