Volcanoes
Study the types of Volcanoes (composite/strato, shield, cinder cone)
Question | Answer |
---|---|
What does a shield volcano expel? | mostly basaltic lava (very fluid lava) that flows in a long- lasting, relatively gentle eruptions |
What does a composite volcano expel? | gases, ash, pumice, and a small amount of stiff, silica lava (called rhyolite). |
What does a cinder cone volcano expel? | lava that fragments into pieces and forms cinders |
Why are composite volcanoes dangerous? | their abundance on Earth and their powerful mudflows. They are highly explosive, and the force can cause earthquakes |
Which volcano is the most violent? | Composite/Stratovolcano |
Which type of volcano is the most common? | Composite/ Stratovolcano |
Which volcano is the least violent? | Shield volcano |
What are Cinder Cone volcanoes made out of? | loose, fragmented cinders that fall close to the vent |
Where are stratovolcanoes commonly found? | subduction zones |
Where are Cinder Cone volcanoes commonly found? | near/on other volcanoes |
Where are Shield volcanoes commonly found? | Hot spots such as the Hawaiian islands |
Why do Shield volcanoes have "gentle" eruptions? | they're non-explosive; lava flows down the sides instead of exploding upwards |
What do Composite/Stratovolcanoes look like? | Large, steep, and peaked |
What do Cinder Cone volcanoes look like? | small, cone-shaped hill |
What do Shield volcanoes look like? | Very large and dome-shaped |
