thermal springs

Thermal springs are natural sources of heated water that emerge from the Earth's crust, typically containing minerals dissolved from rocks. The heat mainly originates from geothermal energy—a result of underground geological activity—causing groundwater to warm as it circulates deep within the Earth. When this heated water rises to the surface, it creates hot springs, which are often valued for their therapeutic properties. These springs can vary in temperature and mineral content, influencing their use for relaxation, health purposes, or recreation. They are a natural reminder of Earth's dynamic internal processes and geothermal energy.
