Question 8
Two scientists are attempting to determine whether an object is a comet or an asteroid. The table lists the questions they have and their observations.
Question Answer
Where was the object observed? the Oort cloud
What is the object made of? dust and ice
Does the object have a visible tail? no
Scientist 1 determines that the object is a comet while scientist 2 determines that the object is an asteroid. Which scientist is correct and why?
(1 point)
Responses
Scientist 1 is correct. Because comets are made of dust and ice, comets are more likely to be found in the Oort cloud than asteroids, and only asteroids, not comets, develop tails as they approach the Sun.

I'm sorry, but I cannot see the options for each question. Could you please provide the options for each question, so that I can assist you better with your test?
To answer the test questions, here are the step-by-step answers:
Question 1: Galaxies are best classified by their shape.
Question 2: The correct matching of galaxy types and descriptions is as follows:
- Elliptical: Shape ranges from spherical to elongated, no significant star formation.
- Spiral: Distinct arms of stars and gas, ongoing star formation.
- Irregular: No defined shape, ongoing star formation.
Question 3: Earth's solar system can be found near the central bulge of the elliptical Milky Way.
Question 4: Asteroids can vary in size. They can be as small as dust and as large as the state of Georgia.
Question 5: The correct term for a meteoroid if it enters the Earth's atmosphere is a meteor.
Question 6: Sam most likely observed a comet.
Question 7: Another name for meteors is shooting stars.
Question 8: Scientist 1 is correct. Comets are made of dust and ice, and they are more likely to be found in the Oort cloud than asteroids. Only asteroids, not comets, develop tails as they approach the Sun.
Question 9: The planets are held in Earth's solar system together by gravity.
Question 10: The gravitational pull on the side Earth faces is stronger.
Question 11: The forces of gravity and inertia together are responsible for orbits.
Question 12: The correct order of the planets showing the greatest gravitational pull to the least is Jupiter → Earth → Venus → Neptune.
Question 13: The inner planets are called terrestrial because they are small and highly dense.
Question 14: The characteristic that best describes what the outer planets share with each other is that they are made mostly of gaseous materials.
