- Hot spring or a thermal spring is a spring with water at temperatures substantially higher than the air temperature of the surrounding region.
 
- Most hot springs discharge groundwater that is heated by shallow intrusions of magma (molten rock) in volcanic areas.
 
- Some thermal springs are not related to volcanic activity.
 
- In such cases, the water is heated by convective circulation.
 
- This means that the groundwater percolating downward reaches depths of a kilometre or more where the temperature of rocks is high because of the normal temperature gradient of the Earth’s crust—about 30 °C (54 °F) per kilometre in the first 10 km (6 miles).
 
- Major hot springs in India:
- Panamik in Nubra valley, Ladakh.
 
- Kheer Ganga hot water spring, Himachal Pradesh
 
- Gaurikund, Kedarnath, Uttarakhand.
 
 
- The study suggested that CO2 in these thermal springs are sourced from metamorphic DE carbonation of carbonate rocks present deep in the Himalayan core.
