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.

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.

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.
