Describe the process of electricity generated by geothermal energy?

Difficulty: Easy

Geothermal energy:

               In some parts of the world, the Earth provides us with hot water from geysers and hot springs. There is a hot molten part, deep in the Earth called magma. Water reaching close to the magma changes to steam due to the high temperature of magma. This energy is called geothermal energy.

Geothermal wells can be built by drilling deep near hot rocks at places, where magma is not very deep. Water is then pushed down into the well. The rocks quickly heat the water and change it into steam. It expands and moves up to the surface. The steam can be piped directly into houses and offices for heating purposes or it can be used to generate electricity.
