Question

Given below are the steps to generate geothermal energy. Arrange the following in correct sequence:

1. It is so hot that when it rises to the earth's surface, it turns into steam.
2. Groundwater in such areas (where the geothermal gradient is high) absorbs heat from the rocks and becomes hot.
3. This steam is used to drive turbines and generate electricity.
4. Geothermal energy exists, because the earth grows progressively hotter with increasing depth.
