Storyboard Text

  • Hello! Today I will tell you all about volcanos! Volcanoes have a pocket of magma beneath the surface called a magma chamber.
  • Around the Pacific ocean, there a circle of volcanos all connected called the ring of fire. A hot spot is an area of magma deep under that melts through the surface to the top and becomes lava.
  • A volcano has many parts. A vent is the hole at the top where the lava comes out of. The pipe, is the tube connecting the magma chamber to the volcano. Lava flow is when the lava flows out the vents in the volcano.
  • There are many different types of volcanos. A dormant volcano does not erupt but can in the future. An Extinct volcano is a volcano that cannot erupt ever again. And active volcano is a volcano that currently erupts and will in the future.
  • Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.
  • The amount of silica in lava can affect the eruption. A volcano erupts quietly if its magma is low in silica. Low-silica magma has low viscosity and flows easily. If it is high in silica it builds up in the volcano’s pipe, plugging it like a cork in a bottle. Dissolved gases, including water vapor, cannot escape from the thick magma. The trapped gases build up the pressure until they explode. The erupting gases and steam push the magma out of the volcano with incredible force.
