Question | Answer |
What are volcanoes? | Volcanoes are openings in the Earth's surface that erupts gases, ash, and lava. |
How do volcanoes form? | Volcanoes form from plate tectonics like: |
Convergent Boundaries | Where plates move together. |
Divergent Boundaries | Where plates move apart. |
Hotspots | Places where magma is close to the Earth's surface. |
Where are volcanoes found and why? | They are found in different areas according to the types of volcanoes. |
Cinder Cone Volcanoes | The smallest of the volcanoes, mildly explosive, but because of the size, there isn't much destruction during eruptions. |
Shield Cone Volcanoes | Wide, large volcanoes, lava isn't viscous - thin and runny and flows out easily. Hawaiian Islands were formed from these types of volcanoes.They're made of basalt, the lava cools as it runs down the sides. |
Composite or Strato Volcanoes | Tall, wide, very, very explosive and extremely dangerous. Viscous lava plugs up cracks in the cone, building pressure, and causing huge explosions. The explosions vaporize part of the mountain causing a pyroclastic flow, hot ash, rock, and lava. |
What magma factors affect the type of eruption? (You will have an example volcano and you will decide what type of magma it holds, due to clues.) | Viscousity? Pressure? Force level? Destruction level? Location? Boundary/hotspot? Ash & pyroclast? |
Can I describe the 3 types of volcanoes? | Cinder Cone, Shield Cone, and Composite/Strato. |
