Answer: a. True
Geothermal energy is the energy that comes from the earth crust. It is a energy which is a source of heat. The heat is produced by the earth by the slow decay of radioactive particles present inside the rocks present in the core region. Also, the hot magma present in the mantle, warms up the water in the geosphere. The heat present in the water utilized as a geothermal energy. The reservoir of the geothermal energy must need to be find out, in order to obtain the energy. For this purpose the earth crust is drilled, which is the first step in harnessing the geothermal energy.
Therefore, the statement one of the first steps in harnessing geothermal energy is to drill a well into a geothermal reservoir is true.
