Volcanoes Quiz

QuestionAnswer
Which type of volcanic eruption is associated with pyroclastic material being released? Why? Composite Volcanoes associate with pyroclastic material because pyroclastic material and hardened lava creates composite volcanoes.
What is the difference between lava and magma? Lava is what comes out of the volcano (outside), magma is inside the volcano.
What process causes hot,solid rock to come up through the mantle over hot spots? Mantle Plume rises
What flows onto Earth's surface during a non-explosive volcanic eruption? Lava
Which type of volcano is least likely to have pyroclastic material flow? Why? Shield Volcanoes are least likely because they form when layers of lava flow out from the vent, harden, and slowly build up to form.
What type of volcano is composed mostly of pyroclastic material? Composite Volcanoes
Volcanic islands can sometimes form over hot spots. What land feature should be under a hot spot? Mantle Plume
What type of volcano has the steepest sides? Why? Composite Volcanoes because it has one exit point at the top.
If a volcano's eruption alternates between quiet and violent eruptions, which type of volcano is it? (ask Miss Sattler tomorrow in advisory!) Composite/Shield Volcanoes
When there are long cracks in Earth's surface and magma can sometimes erupt from them, what are the cracks called Fissure eruptions
What volcanic feature forms a small depression around a volcano's vent? Volcanic Crater
What are two land features that are formed by volcanoes? How are they exactly formed? One land feature is islands. They form when volcanoes come up from the ocean they form into an island. Another one is reefs. They form when volcanoes come out of the ocean but not all the way to the top and are dormant.
What else happens when reefs form? Eventually corral and animals make their homes.
