Question

If you ever have a chance, you must go see the geysers at Yellowstone National Park. Geysers are holes in the ground where hot water and steam shoot out. The pressure under the ground becomes so high and the water is so hot that it can't stay underground. When the water cools down, it stops shooting out of the ground. Then the process starts over.

If something happens to the way the rocks are formed underground, a geyser could change or even stop. People can ruin a geyser if they throw trash into it. Geysers are very neat to see. We must take care of them so that other people can see them, too.
