Question

1. the passage mentions that the impact \triggered earthquakes and volcanic activity around the world.\ which piece of textual evidence most directly explains why this global seismic activity occurred?

a. the initial crater cavity measured about 100 km wide and 30 km deep.
b. the impact produced 25 trillion metric tons of molten material.
c. the shockwave from the asteroid caused earthquakes and volcanic activity worldwide.
d. the liftboat myrtle transformed into a drilling platform.

1. which best describes the author’s purpose in the final paragraph of page 3 (the paragraph quoting catherine ross and discussing craters as \cradles of life\)? a. to argue that studying craters has no value for science

b. to show that crater research can help us understand earth’s early history and habitability and has value for studying other planets
c. to provide technical drilling instructions for future expeditions
d. to claim that the chicxulub crater caused modern cities to be flooded

Explanation:

Question 9

To answer this, we analyze each option:

• Option A: Describes the crater's size, not the cause of seismic activity.
• Option B: Talks about molten material, not the direct cause of global seismic activity.
• Option C: States that the shockwave from the asteroid caused the worldwide earthquakes and volcanic activity, directly explaining the global seismic activity.
• Option D: Is about a liftboat, irrelevant to the impact's seismic effects.

Analyzing each option:

• Option A: Contradicts, as the paragraph likely shows value in crater study.
• Option B: The mention of craters as "cradles of life" and quoting Catherine Ross suggests the purpose is to show crater research helps understand Earth's history, habitability, and other planets' study.
• Option C: The paragraph is not about drilling instructions.
• Option D: The paragraph doesn't discuss modern cities flooding due to the crater.

Answer:

C. The shockwave from the asteroid caused earthquakes and volcanic activity worldwide.
