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.
Answers
Answer:
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.
Geothermal energy
Explanation:
Geothermal energy:
Due to geological changes, molten rocks in the Earth's crust are pushed upward and trapped in certain regions. Such regions are called 'Hot spots'. The heat energy obtained from such hot sports are used to run the turbines and generate electricity. The energy so produced is called geothermal energy.
Advantages: Cost of production of electricity is low.
Limitation: There are very few commercially-viable sites where such energy can be exploited.
