Hot spring. Hot pools at a geothermal spring. The water has been heated underground by hot rocks. Geothermal springs are generally found in areas where the earth's crust is thin,allowing our planet's internal heat to escape. This internal heat comes from the decay of radioactive elements,chemical changes occurring under great pressure,and geological movements. Photographed at Hell's Gate on North Island,New Zealand | |
