100-Volcano CharacteristicsMagma Composition at Volcanoes

Where can a volcano form?

Answer

ANSWER 100-Volcano CharacteristicsMagma Composition at Volcanoes

Along plate boundaries. Anywhere magma can form.

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.

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.

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.

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.

100- Explosive EruptionEffusive Eruptions

Fill in blank.Large, explosive eruptions contain more energy than an _______________.

Answer

ANSWER 100- Explosive EruptionEffusive Eruptions

Atomic bomb

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.

Why is effusive much less deadly?

Answer

ANSWER 300- Explosive EruptionEffusive Eruptions

Slower, so people can evacuate.

What are the three type of lava flow?

Answer

ANSWER 400- Explosive EruptionEffusive Eruptions• Aa• Pahoehoe• Pillow Lava

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.

100-Types of VolcanoesSuper volcanoes

True or FalseA super volcano is a very rare event in Earth's history?

Answer

ANSWER 100-Types of VolcanoesSuper volcanoes

What is the shape of the volcano directly related to?

Answer

ANSWER 200-Types of VolcanoesSuper volcanoes

Magma composition

Name the three shapes of a volcano.

Answer

ANSWER 300-Types of VolcanoesSuper volcanoes• composite cone• shield cone• cinder cone

Explain the shape of the three types of volcanoes.

Answer

ANSWER 400-Types of VolcanoesSuper volcanoes• Composite cone: Built in layers• Shield cone: Large, gently sloping volcano• Cinder cone: Distinct cone shape

Name a place that is considered as a super volcano.

Answer

ANSWER 500-Types of VolcanoesSuper volcanoes• Yellowstone park

100-Volcanoes at HotspotsPredicting Volcanic Eruptions

Is predicting volcanic eruptions harder to predict or is earthquakes harder to predict?

Answer

ANSWER 100-Volcanoes at HotspotsPredicting Volcanic Eruptions

Earthquakes are harder to predict.

What is interplate volcanism?

Answer

When a volcano occurs in the middle of plates.

Define mantle plume

Answer

Mantle plume: An upwelling of upwelling of unusually hot mantle plume

Define hotspots.

Answer

Hotspots: a magma chamber developed above the mantle plume

How do scientists predict volcanic eruptions? Name three factors that can be taken into account.

Answer

ANSWER 500-Volcanoes at HotspotsPredicting Volcanic Eruptions• history of activity• earthquakes• slope deformation • gas emission
