Where does water from hot springs come from?
Hot springs can form in several ways, but most commonly occur when rainwater or groundwater is heated by magma underneath Earth’s surface. Cracks or faults in the Earth’s surface allow water to flow deeper towards the mantle, where it comes in contact with hot rocks that heat the water.
How is the geothermal activity in Iceland being used?
Iceland is a pioneer in the use of geothermal energy for space heating. Generating electricity with geothermal energy has increased significantly in recent years. Geothermal power facilities currently generate 25% of the country’s total electricity production.
Why is the ground hot in Iceland?
Geothermal energy in Iceland Shaped by fierce natural forces, straddling the Mid-Atlantic Ridge where the activity of divergent tectonic plates brings heat and magma closer to the earth´s surface, Iceland holds enormous geothermal resources. The energy comes rather cheap.
Where are most geothermal reservoirs of hot water located?
