Hot springs

Definition

Hot springs are natural water sources where geothermally heated groundwater flows to the surface, often resulting in warm or hot water pools. They are formed when subterranean water is heated by magma or hot rocks, creating conditions that allow the water to rise through fractures in the Earth's crust. Hot springs are significant as they represent a renewable energy resource and play an important role in geothermal energy exploration and exploitation.

5 Must Know Facts For Your Next Test

1. Hot springs are found all over the world, with famous examples including Yellowstone National Park in the United States and the Blue Lagoon in Iceland.
2. The temperature of hot springs can vary widely, ranging from just above body temperature to over 200°F (93°C) in some cases, depending on the geothermal gradient and local geology.
3. Hot springs can contain dissolved minerals like sulfur, silica, and various salts, which contribute to their distinct colors and therapeutic properties.
4. In addition to recreation and tourism, hot springs can be utilized for heating buildings, growing crops in greenhouses, and even generating electricity through geothermal power plants.
5. Environmental considerations are essential in hot spring exploitation to ensure sustainable use while minimizing impacts on local ecosystems.

Review Questions
