Boiling mud pool at a geothermal spring. This close-up view looking down inside a pool shows bubbles rising from water boiling through the mud. Mud pools like this are generally found in areas where the earth's crust is thin,allowing internal heat to escape to the surface. This internal heat comes from the decay of radioactive elements,chemical changes occurring under great pressure,and geological movements. Photographed on North Island,New Zealand | |
