3. Does a volcanic eruption also do good things?
When a volcano erupts there are also some good things for example the ash of a volcano makes the ground very fertile. Because the ash of a volcano easily gets weathered by rain which makes it a perfect soil to farm on. It also creates new islands by erupting in an ocean that's laying on a hotspot. Some other things which we don’t see as useful are maybe good too. For example, because of eruptions people are now aware of the danger and they created special plans to evacuate the area hours before the volcano erupts.
