Draw the typical shape of a short-period comet’s orbit in our solar system. What is this shape called? ____________________________________________________ ___________________________________________________________________ ___________________________________________________________________ Multiple Choice 1. Where do comets come from? a) inside Jupiter’s orbit b) from other parts of the galaxy c) a cloud of solar system debris between us and the nearest star d) the direction of Alpha Centauri 2. What are comets made of? a) dust and rock b) a mixture of dust, rocky material and frozen gases c) Coronene and other organic substances d) ice and carbon dioxide 3. What is the period of a comet? a) the time it takes for the comet to travel once around the Sun b) the shortest distance from the Sun to the comet along the comet’s path c) the number of times the comet orbits the Sun in a millennium d) the amount of time between sightings of the comet from Earth 4. What is a short-period comet? a) a comet whose orbit has been perturbed into a very flat ellipse b) one whose orbit has been pulled into the inner solar system by gravity c) one that approaches the sun at least every 10,000 years d) one that comes very close to the sun 5. What is a long period comet? a) one that stays outside the orbit of Pluto b) a comet that is still in the Oort cloud c) one with a period of more than 50 years d) a comet whose orbit takes it near the Sun every 10,000 years or more 6. What kind of period does Comet Halley have? a) short b) medium c) long 7. Where is the Sun within a comet’s orbit a) near the perihelion b) at one focus of an elliptical orbit c) at the center of a circluar d) any of the above 8. What is a meteor? a) a comet that enters the Earth’s atmosphere b) debris left behind by a comet as is passes near the sun c) a shooting star d) a rocky left-over from the formation of the planets 9. What is an asteroid? a) a rocky left-over from the formation of the planets b) debris left behind by a comet as is passes near the sun c) a fragment of a moon that was hit by a comet d) a cosmic “dirty snowball” 10. What is the Alvarez Hypothesis? a) an intrinsic gradualist theory of mass extinction b) an extrinsic catastrophist theory of mass extinction c) the idea that dinosaurs became extinct after a large object hit the Earth and cause severe climate changes d) a and c e) b and c Summarize Using the facts that you have collected during our investigation of the comet on the internet, write a summary about how a new comet begins its life. Be sure to put the information in order. ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________ ______________________________________________________________________
