Volcanoes and Arenal!!!
Each type of volcano is associated with a certain type of lava.
Volcanoes are usually fed by a large reserve of magma that collects in a large underground cavity called a magma chamber.
Magma is more buoyant than the surrounding rock so it naturally pushes upward.
When the pressure is high enough the magma shoots up through a long shaft.
Geysers are springs that throw boiling water high in the air. They are caused by volcanic heat warming trapped ground water. Algunos volcanes despues de un erupcion grande se colapsan y hacen un enorme depresion.
Magma es roca liquido que erupte de un volcan cuando hay bastante presion.
Cada typo de volcan tiene diferentes typs de lava.
El volcan mas grande que todavia es activo es Mauna Loa en Hawaii.
200,000 personas perdieron sus vidas por volcanes en 500 anos.
