Introduction to Volcanoes Grade 4 Quiz

What is a volcano?

• A mountain that opens downward to a pool of molten rock

• A type of bird that can fly at high altitudes

• A type of flower that grows in the desert

• A large body of water surrounded by land

During their field trip to a volcano, Emily, Everly, Lauren, and Victoria learned about the main vent of a volcano. What is the main vent of a volcano called?

• Pit

• Chasm

• Crater

• Hole

Explain the difference between active, dormant, and extinct volcanoes.

• Active, dormant, and extinct volcanoes are all the same in terms of their activity levels.

• Active volcanoes are the ones that have never erupted before.

• Active, dormant, and extinct volcanoes differ in their current and potential activity levels.

• Dormant volcanoes are the ones that are currently erupting.

How are volcanoes formed?

• By the movement of tectonic plates and the release of pressure from the Earth's mantle.

• By the impact of meteorites

• By the eruption of underground gas pockets

• By the melting of ice caps

What are the dangers of living near a volcano?

• Hurricanes

• Earthquakes

• Potential dangers include lava flows, ash fall, pyroclastic flows, and volcanic gases.

• Tornadoes

Describe the process of a volcanic eruption.

• The process of a volcanic eruption involves the release of water from the Earth's mantle through a vent or opening in the Earth's crust.

• Volcanic eruptions are caused by the movement of tectonic plates.

• The process of a volcanic eruption involves the release of magma from the Earth's mantle through a vent or opening in the Earth's crust. This magma can then flow as lava, ash, and gases, causing an eruption.

• A volcanic eruption occurs when a volcano becomes dormant and stops releasing magma.

How do volcanoes affect the environment?

• Volcanoes create a healthier atmosphere

• Volcanoes have no impact on the environment

• Volcanoes help in preserving habitats

• Volcanoes release gases, ash, and lava which can lead to air pollution, climate change, and destruction of habitats.

During their geography class, Emily, Victoria, Everly, Niahana, and Lauren were discussing famous volcanoes around the world. What are some famous volcanoes around the world?

• Mount Rushmore, Mount St. Helens, Mount Rainier

• Mount Everest, Mount Kilimanjaro, Mount McKinley

• Mount Olympus, Mount Rushmore, Mount Kilimanjaro

• Mount Vesuvius, Mount Etna, Mount Fuji, Mauna Loa, Krakatoa

What are the potential hazards of living near a volcano?

• Tsunamis

• Volcanic lightning

• Pyroclastic flows, lahars, and volcanic gases

• Blizzards

Discuss the differences between an active, dormant, and extinct volcano.

• Active volcanoes are those that have never erupted before.

• Dormant volcanoes are the ones that are currently erupting.

• Active, dormant, and extinct volcanoes differ in their current and potential activity levels.

• Extinct volcanoes are the ones that are currently erupting.
