Amplify Unit 7: Geology Chapter 4 Quiz

Why might volcanic eruptions be considered both destructive and creative?

Clue: Look for the section that describes how volcanoes create new land and bring minerals but also cause damage, like lava flows and ash.

• They only cause destruction to forests.

• They create new land but also cause damage.

• They have no effect on the environment.

• They only cause earthquakes.

How does the eruption of a volcano like Tambora affect the climate?

Clue: Check the part of the text that talks about the eruption of Tambora and how it affected the weather in 1816, called 'The Year Without a Summer.'

• It cools the Earth by blocking sunlight with ash.

• It increases the Earth's temperature.

• It causes large rainstorms.

• It has no effect on the weather.

What might happen to Hawaii’s volcanic islands over time as the Pacific Plate moves?

Clue: Look in the section about how the Hawaiian Islands were formed and how they will continue to form as the Pacific Plate moves.

• The islands will sink into the ocean.

• The islands will remain in the same place forever.

• New islands will form as the plate moves over the hotspot.

• The islands will split into two separate islands.

How would you compare an active volcano to a dormant volcano?

Clue: Check the section where volcanoes are defined as 'active' or 'dormant,' and how the text explains the difference.

• An active volcano erupts regularly, while a dormant volcano has not erupted in over 10,000 years.

• An active volcano erupts when it feels like it, while a dormant volcano is always erupting.

• An active volcano erupts regularly, while a dormant volcano is unlikely to erupt again.

• There is no difference between an active and dormant volcano.

What can we infer about the danger of volcanic eruptions based on the examples in the text?

• Volcanic eruptions are always predictable and safe.

• Volcanic eruptions can be both dangerous and unpredictable.

Why do you think the eruption of a hotspot volcano forms a chain of islands over time?

Clue: Read the section about how hotspots form chains of islands over time, using the example of the Hawaiian Islands.

• Because tectonic plates stay in the same place.

• Because the volcano constantly erupts in the same location as the plate moves.

• Because the ocean is shallow in these areas.

• Because earthquakes prevent movement.

What conclusion can we draw from the fact that some volcanoes form along subduction zones?

Clue: Look in the section that talks about subduction zones and how volcanoes form when tectonic plates collide.

• Volcanoes always form in the middle of continents.

• Volcanoes form where tectonic plates meet and one plate slides under another.

• Volcanoes only form near the ocean.

• Volcanoes are not affected by tectonic plates.

If you were to visit Yellowstone National Park, what would you expect to see? Clue: Find the part about Yellowstone and its famous geysers, hot springs, and volcanic activity.

• Hot springs, geysers, and possibly volcanic activity.

• Only cold lakes and icy mountains.

• Desert-like conditions and no volcanic features.

• A flat, dry landscape with no water features.

What might happen if a volcano like Kilauea suddenly stopped erupting?

Clue: Check the description of Kilauea and how it is still active, as well as the difference between dormant and extinct volcanoes.

• It would quickly become extinct.

• It would likely remain dormant and could erupt again in the future.

• It would start forming new mountains.

• It would turn into a desert.

Scarlett is studying the potential risk of volcanic eruptions around the Pacific Ring of Fire for her geography project. Based on the text, how would you evaluate the potential risk?

• It’s very low because volcanoes in this region never erupt.

• It’s very high because the Ring of Fire is one of the most volcanically active regions.

• It’s moderate because there are only a few volcanoes.
