answer 100 volcano characteristics magma composition at volcanoes
ANSWER 100-Volcano CharacteristicsMagma Composition at Volcanoes

Along plate boundaries. Anywhere magma can form.

200 volcano characteristics magma composition at volcanoes
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 characteristics magma composition at volcanoes
ANSWER 200-Volcano CharacteristicsMagma Composition at Volcanoes

If temperature rises, if pressure lowers, and if water is added.

300 volcano characteristics magma composition at volcanoes
300-Volcano CharacteristicsMagma Composition at Volcanoes

Name and explain the three stages of a volcano.

answer 300 volcano characteristics magma composition at volcanoes
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.
answer 400 volcano characteristics magma composition at volcanoes
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 characteristics magma composition at volcanoes
500-Volcano CharacteristicsMagma Composition at Volcanoes

What are three things magma composition determine?

answer 500 volcano characteristics magma composition at volcanoes
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 eruption effusive eruptions
100- Explosive EruptionEffusive Eruptions

Fill in blank.

Large, explosive eruptions contain more energy than an _______________.

answer 200 explosive eruption effusive eruptions
ANSWER 200- Explosive EruptionEffusive Eruptions
  • The combination of tephra, ash, and gas that reach unreal speeds down a slope.
300 explosive eruption effusive eruptions
300- Explosive EruptionEffusive Eruptions

Why is effusive much less deadly?

4 00 explosive eruption effusive eruptions
400- Explosive EruptionEffusive Eruptions

What are the three type of lava flow?

5 00 explosive eruption effusive eruptions
500- Explosive EruptionEffusive Eruptions

Explain the three types of lava flows.

answer 500 explosive eruption effusive eruptions
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.
