How do geothermal power stations work?

Cold water is heated up and the water power turbines under the water and turns it into electricity!

The hot water from inside the earth is pumped to produce steam to power turbines then creating electricity !

he hot water from inside the earth meets cold air and produces condensation which powers the turbines and turns it into electricity!
