1. What are the likely consequences if a 200 m asteroid struck the center of a 3 million-person city?
A. less than 10 percent of the city destroyed
B. about 50 percent of the city destroyed
C. near complete destruction
2. Where do most asteroids originate?
A. between Mars and Jupiter
B. between the moon and Mars
C. from the Kuiper belt
3. Which type of NEO explodes in the atmosphere before reaching the Earth’s surface?
A. asteroid
B. meteorite
C. bolide
4. What comprises a comet?
A. ice
B. rock
C. both ice and rock
5. How do we know where comets come from?
A. Those that come from the Kuiper belt are composed of slightly different materials than those from the Oort cloud.
B. The comets from the Oort cloud don’t produce a tail, but those from the Kuiper belt do.
C. The comets from the Oort cloud travel at much greater velocities than those from the Kuiper belt.
D. The comets from either location have a trajectory or pathway that can be traced back to their starting point once we see them.
E. Astronomers only guess where these comets come from – they don’t know for sure.
6. ______________ is name given to NEO’s composed of rocky and/or metallic material that are best described as
A. Comets; dirty snowballs that are vaporized by the solar wind as they get near the sun.
B. Meteorites; small clumps of cosmic material that originated in the Oort cloud.
C. Asteroids; small chunks of rock knocked loose from a belt between Mars and Jupiter.
D. Bolides; space debris that bounces off of other stuff in space.
E. None of these choices are correct.
7. Most meteors that strike the Earth’s atmosphere
A. pass through the atmosphere and commonly land in the ocean.
B. commonly burn up in the atmosphere and never reach the ground.
C. pass through the atmosphere and commonly land on continents.
D. are from the Oort cloud as determined from their chemical composition.
E. are from comets that passed too close to the earth and broke up into little pieces.
8. Earth was constructed by the accumulation of material similar to that of many asteroids, meteors and comets.
