Volcanoes and Lava types.
First I am going to tell you about some volcanoes.The cinder cone volcano is made from loose graiany cinders and almost no lava!! The sheild volcano can reach almost 100 miles across it's base!! WOW!(: Last is the Composite Volcano. This is the type of volcano Mount Saint Helens is!
Now i will tell you about some Lavas. The lower viscosity a volcano has the runnier the lava gets. There are 4 types of lavas we learned about, High Water/Low Silica, High Water/High Silica which is my favorite because it explodes out of the ground!! isnt that cool??? So anyway there is also the Low Water/Low Silica and also there is Low Water/High Silica. I really hope you learned something from my article.
