Geothermal power plants drill into the ground to extract hot steam which is used to turn the turbines. This can be done in 2 different ways, by just drilling into the ground electrical to kineticand letting steam escape into the turbine (dry steam method)potential energy to kinetic which makes turbines turn, or extracting hot water from the ground and lowering the pressure of it to flash it into steam, which is then used to turn the turbine (flash steam method)basically heat to mechanical energy. The steam used to turn the turbine is then condensed back into water, and then either used for different purposes around the power plant, or returned to the Earth, making geothermal energy sustainable.SalmanPakRocks said:(e)Describe the processes by which the energy is converted from one form to another, including reference to
(4) Geothermal energy
Summarising it, The energy changes involved in geothermal energy are heat and electrical, as the heat from the hot rocks underground heat the steam which in turn powers the turbine to create electrical energy.
