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
ANSWER 200-Volcano CharacteristicsMagma Composition at Volcanoes
If temperature rises, if pressure lowers, and if water is added.
Home
300-Volcano CharacteristicsMagma Composition at Volcanoes
Name and explain the three stages of a volcano.
Answer
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.
Home
400-Volcano CharacteristicsMagma Composition at Volcanoes
Explain mafic magma and felsic magma.
Answer
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.
Home
500-Volcano CharacteristicsMagma Composition at Volcanoes
What are three things magma composition determine?
Answer
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.

200- Explosive EruptionEffusive Eruptions
What is a pyroclastic flow?
Answer
ANSWER 200- Explosive EruptionEffusive Eruptions• The combination of tephra, ash, and gas that reach
unreal speeds down a slope.
Home
300- Explosive EruptionEffusive Eruptions
Why is effusive much less deadly?
Answer
ANSWER 300- Explosive EruptionEffusive Eruptions
Slower, so people can evacuate.

400- Explosive EruptionEffusive Eruptions
What are the three type of lava flow?
Answer
ANSWER 400- Explosive EruptionEffusive Eruptions• Aa• Pahoehoe• Pillow Lava
Home
500- Explosive EruptionEffusive Eruptions
Explain the three types of lava flows.
Answer
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.
