Natural Science CLEP Prep Practice Exam

Asteroids and comets both form after collisions of debris, but they are not the same type of object. Comets are made of ice and dust, while asteroids are made of rock and metal. Even though some asteroids may contain ice, that does not make them the same as comets. Asteroids and comets also have different orbits and origins, with asteroids typically found in the main asteroid belt between Mars and Jupiter and comets originating from the Kuiper Belt or Oort Cloud. Therefore, option B is the most accurate answer as it highlights the similarity between the formation of asteroids and comets while also acknowledging their distinct differences.
