State the meaning of the term “hot spot” in the context of earth crust. Write one advantage and one limitation of utilizing energy obtained from the hot spots.

Hotspot is a region, where a molten rock is trapped. It is formed in the deeper hot regions of Earth’s crust, is pushes upwards through geological changes.

When underground water comes in contact with hotspot, a stream is generated. This steam trapped in turbines is routed through a pipe to a turbine and is used to generate electricity.


Sometimes hot water from that region also finds an outlet. It is known as hot springs.


Advantage: cost of production is not much


Disadvantage: there are very few such commercially viable sites, where energy can be exploited.
