Praxis 5005 Practice Question
Which of the following best describes a comet?
Correct Answer: C
Rationale: A comet is best described as a chunk composed primarily of rock, ice, and dust orbiting the Sun in an elliptical path. This definition captures the essential characteristics of comets, including their composition and orbital behavior.
Option A describes an asteroid, which is typically a small rocky body found mainly between Mars and Jupiter. Option B refers to a meteoroid, which is a metal or rocky fragment that burns up upon entering Earth's atmosphere. Option D describes sunspots, which are temporary dark regions on the Sun's surface caused by magnetic activity. Each of these options misrepresents the unique features of a comet, making option C the most accurate choice.
