Volcanoes: Intrusive and Extrusive Quiz

What is the main difference between intrusive and extrusive volcanoes?

• Color of the lava

• Type of rocks formed

• Location of the magma

• Size of the volcano

How are intrusive volcanoes formed?

• Intrusive volcanoes are formed by the accumulation of snow and ice

• Magma solidifies below the Earth's surface

• Volcanoes are formed by the cooling of ocean water

• Intrusive volcanoes are formed by the eruption of lava onto the Earth's surface

What are the characteristics of extrusive volcanoes?

• Formation from lava that flows deep underground and cools slowly

• Characterized by slow-moving lava that forms a dome shape

• Result from the explosion of hot gases and ash from within the Earth

• Formation from lava that flows onto the Earth's surface and cools quickly

Explain the formation of extrusive volcanoes.

• Extrusive volcanoes are created by the erosion of mountain ranges.

• Extrusive volcanoes are formed by the accumulation of sedimentary rocks over time.

• Extrusive volcanoes are the result of tectonic plate movement.

• Magma from within the Earth is expelled onto the surface as lava, which then cools and solidifies to form volcanic rock.

What are the characteristics of intrusive volcanoes?

• Intrusive volcanoes are formed by the accumulation of water beneath the Earth's surface, and they have a characteristic cone-shaped appearance.

• Intrusive volcanoes are formed by the accumulation of magma beneath the Earth's surface, and they have a characteristic dome-shaped appearance.

• Intrusive volcanoes are formed by the accumulation of lava on the Earth's surface, and they have a characteristic flat appearance.

• Intrusive volcanoes are formed by the accumulation of ice beneath the Earth's surface, and they have a characteristic pyramid-shaped appearance.

Describe the process of formation of intrusive volcanoes.

• Magma solidifying beneath the Earth's surface

• Magma solidifying above the Earth's surface

• Magma turning into gas beneath the Earth's surface

• Magma flowing out of the Earth's surface

What type of magma is associated with extrusive volcanoes?

• Rhyolitic magma

• Andesitic magma

• Basaltic magma

• Granitic magma

What type of magma is associated with intrusive volcanoes?

• Felsic magma

• Mafic magma

• Ultramafic magma

• Intermediate magma

List some examples of intrusive volcanoes.

• Calderas

• Stratovolcanoes, also known as composite volcanoes, and lava domes

• Cinder cone volcanoes

• Shield volcanoes

List some examples of extrusive volcanoes.

• Yellowstone Caldera, Krakatoa, Mount Vesuvius

• Grand Teton, Denali, Mount Rainier

• Mount Everest, Mount Fuji, Mount Kilimanjaro

• Mount St. Helens, Mauna Loa, Mount Etna
