Yellowstone

       I chose Yellowstone for my project on the USA and I made a Power Point presentation and a talk. I chose Yellowstone because it was interesting.
      I found out about a lot of new things. For example the park is called Yellowstone because of the Yellowstone Lake. I also found out about what a caldera is and how many earthquakes there are a  year. A caldera is a lake on a volcano which is created when an empty magma chamber collapses. With time the collapsed chamber will be filled up with water. In Yellowstone there are about 3000 earthquakes a year. The last three super eruptions were 2,1 mio. 1,2 mio. and 640.000 mio. years ago.
      It was fun to read and write about Yellowstone.
