Explanation:

These are multiple - choice questions related to astronomy and geology topics such as asteroids, meteorites, and early Earth life. Knowledge of astronomical events, natural resources related to impacts, and characteristics of meteorites is required to answer them.

Answer:

1. A. Nickel (The Chicxulub impact is linked to nickel - rich deposits)
2. A. If it happened in the past, it could happen again (Based on the historical evidence of asteroid impacts)
3. A. Oct 9, 1992 (The Peekskill fireball event occurred on this date)
4. A. 4,500 (Approximate number of small - sized meteorites over 2 lbs hitting Earth each year)
5. C. Clovis (Evidence of Clovis people has been found in some archaeological sites)
6. B. mega - mammals (Wooly mammoth and American mastodon are examples)
7. A. A fuzzy "squashed comet" (Discovered near Jupiter by Carolyn Shoemaker and team)
8. B. False (There have been observations of comet impacts)
9. B. ripples (Comet pieces exploding in Jupiter's atmosphere cause ripples)
10. B. Tunguska (Hit by an airburst in 1908)
11. C. 1,000 yrs. (Statistical estimate for such events)
12. A. Leftover pieces of asteroids (Contain information about solar system origins)
13. B. Metal detectors (Used to hunt meteorites)
