Texte du Storyboard
- Hi My Name is Erah Cabico of Grade 9- TungstenWhat comes into your mind when you heard Volcano?
- Natural Disaster?
- Yes Natural Disaster.Volcano is is an opening in the earth's crust through which lava, volcanic ash, and gases escape.
- Step 1:
- Volcanoes are formed when magma from Earth's upper mantle gets to the surface. As the magma rises, it melts holes in the rock which then forms a magma chamber.
- How a Volcano erupt?
- Step 2:
- The erupted materials then pile up around the vent, which then forms a volcano. The crater is a bowl shape, it forms on the top of the volcano. The vent is at the bottom of the crater.
- Step 3:
- The Volcano then erupts, chunks of hot rock, red hot ash and cinders spew out and massive fierce clouds (ash clouds) rise above the mountain (volcano).
- Step 4:
- When lava erupts, it glows red hot to white hot as the lava flows. The volcanic materials erupt through the central vent. But other magma escape through the main conduit wall and go into smaller channels.
