Amplify Unit 7: Geology Chapter 4 Flashcard

Front

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.

Back

They create new land but also cause damage.

Front

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.'

Back

It cools the Earth by blocking sunlight with ash.

Front

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.

Back

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

Front

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

Back

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

Front

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

Back

Volcanic eruptions can be both dangerous and unpredictable.

Front

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.

Back

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

Front

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. Options: 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.

Back

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

Front

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.

Back

Hot springs, geysers, and possibly volcanic activity.

Front

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.

Back

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

Front

Based on the text, how would you evaluate the potential risk of volcanic eruptions around the Pacific Ring of Fire?

Back

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