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.

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 a comet would not develop a visible tail that far away from the Sun.

Scientist 2 is correct. Because asteroids are made of dust and ice, asteroids are more likely to be found in the Oort cloud than comets, and an asteroid would not develop a visible tail that far away from the Sun.

Scientist 1 is correct. The observations provided indicate that the object was observed in the Oort cloud, is made of dust and ice, and does not have a visible tail. Based on these observations, we can conclude that the object is a comet.
Comets are composed of dust and ice, are more likely to be found in the Oort cloud, and develop visible tails as they approach the Sun. On the other hand, asteroids are mainly composed of rock and metal, are not typically found in the Oort cloud, and do not develop tails.
Therefore, Scientist 1 correctly determined that the object is a comet.
