VITAL SIGNS OF THE EARTH
Q. Why does Norris Geyser Basin look so stark and change so dramatically and frequently?
A. Research has revealed that many factors are responsible, including:
1. high underground temperatures;
2. a mixture of acidic and neutral waters;
3. hydrothermal explosions;
4. thermal disturbances;
5. high concentrations of dissolved silica;
6. and the flow of hydrothermal fluids.
