What are hot spots inside earth's crust?
Official answer
Hot spots are specific regions inside the Earth's crust where molten rocks, formed in deeper hot regions due to geological changes, are pushed upward and trapped.
Marking scheme
- 1.Definition of hot spots as regions where molten rocks are trapped: 1 Mark
Hint
Think about geothermal energy and what happens to molten rocks trapped in the Earth's crust.
Quick oral answer
Hot spots are regions in the Earth's crust where molten rocks are pushed up and trapped due to geological changes.
Common mistakes
- 1.Confusing geothermal hot spots with biodiversity hot spots.
- 2.Describing them simply as volcanic regions without mentioning the trapping of molten rocks.
Analysis and explanation
Due to geological changes, molten rocks formed in the deeper hot regions of the Earth's crust are pushed upward and become trapped in certain localized regions. These regions are known as 'hot spots'. When underground water comes in contact with these hot spots, steam is generated, which can be harnessed to produce geothermal energy.
Interesting facts
The steam trapped in these hot spots can be routed through pipes to spin turbines and generate electricity, providing a highly reliable source of renewable energy known as geothermal energy.
