Shield Volcanoes

by Nathaniel



A good way to describe what happens when a volcano erupts is by shaking a bottle of soda pop. A shield volcano erupts by plate-tectonics. This will build pressure caused by a chemical reaction. Usually there are signs a volcano will erupt soon. Under each volcano hot magma is stored in chambers. The magma chamber is full of magma. Both sides of the volcano bulge. Most of the time there are earthquakes right before a volcano is going to erupt. Sometimes volcanoes erupt for three to four weeks and then they rest. After a volcano erupts it is usually not as dangerous for the people that live on it.
