3. A geyser is a place where hot water and steam shoot up from
   inside the earth onto its surface. A geyser forms when water
   seeps into the earth and comes in contact with the earth’s hot
   mantle. The heat from the mantle causes the water to change
   to steam and erupt through cracks in the earth’s crust.


4. Mira’s father explained that some small geysers bubble all day
   long in water pools, instead of shooting water into the air.
   Phillip would like to visit Yellowstone National Park to see
   geysers.
