Active Earth

This term we are learning about Active Earth. We are first studying about volcano's and how they have eruptions. Volcano's need pressure so they can erupt. Yesterday we were doing experiments of pressure on balloons. Here is some information for you to read.

Volcanos can erupt under water.
Active volcanos can erupt.
Dormant volcanos erupted ages's ago and it might again someday.
