shows how geothermal energy is used to produce electricity. Summarise the information by selecting and reporting the main features , and make comparisons where relevant.

The picture illustrates the linear stages in the power plant that uses geothermal to produce electricity. Three main stages are shown in the diagram. It starts from cold water which is injected into the hot rocks zone to create steam and rotate the turbine. Beginning at the injection process, cold water from the surface is injected into the deep of the earth or the injection well, the depth which has a very high temperature is located about 4.5 kilometres below the surface. After that, water is going through the hot rock zone and gets heated up. In the production well, the hot liquid is pumped up to the earth's surface again.
