100-Volcano CharacteristicsMagma Composition at Volcanoes Where can a volcano form?
ANSWER 100-Volcano CharacteristicsMagma Composition at Volcanoes Along plate boundaries. Anywhere magma can form.
200-Volcano CharacteristicsMagma Composition at Volcanoes Volcanoes erupt because mantle rocks melts and becomes magma. What are the three conditions mantle rocks can melt?
ANSWER 200-Volcano CharacteristicsMagma Composition at Volcanoes If temperature rises, if pressure lowers, and if water is added.
300-Volcano CharacteristicsMagma Composition at Volcanoes Name and explain the three stages of a volcano.
ANSWER 300-Volcano CharacteristicsMagma Composition at Volcanoes • Active: Currently erupting or showing signs of eruption. • Dormant: No currently activity, but has erupted recently. • Extinct: no activity for some time, probably will never erupt again.
400-Volcano CharacteristicsMagma Composition at Volcanoes Explain mafic magma and felsic magma.
ANSWER 400-Volcano CharacteristicsMagma Composition at Volcanoes • Mafic: low in silica. Contain dark magnesium and iron-rich minerals • Felsic: high in silica. Contain light minerals, commonly quartz.
500-Volcano CharacteristicsMagma Composition at Volcanoes What are three things magma composition determine?
ANSWER 500-Volcano CharacteristicsMagma Composition at Volcanoes • Eruption style, the type of volcanic cone that forms, and the composition of rocks found at the volcano.
100- Explosive EruptionEffusive Eruptions Fill in blank. Large, explosive eruptions contain more energy than an _______________.
ANSWER 100- Explosive EruptionEffusive Eruptions Atomic bomb
200- Explosive EruptionEffusive Eruptions What is a pyroclastic flow?
ANSWER 200- Explosive EruptionEffusive Eruptions • The combination of tephra, ash, and gas that reach unreal speeds down a slope.
300- Explosive EruptionEffusive Eruptions Why is effusive much less deadly?
ANSWER 300- Explosive EruptionEffusive Eruptions Slower, so people can evacuate.
400- Explosive EruptionEffusive Eruptions What are the three type of lava flow?
ANSWER 400- Explosive EruptionEffusive Eruptions • Aa • Pahoehoe • Pillow Lava
500- Explosive EruptionEffusive Eruptions Explain the three types of lava flows.
ANSWER 500- Explosive EruptionEffusive Eruptions • Aa: slightly viscous forms rough jagged layers of lava. • Pahoehoe: Not viscous forms ropy, smooth layers of lava • Pillow Lava: under water lava flows cool quickly into spherical rocks, common at mid-ocean ridges.
