Most meteoroids are:
A) rock-sized pieces of ice chipped off comets.
B) centimeter-sized pieces of interstellar matter.
C) fragments of asteroids.
D) small pieces of debris from the original solar nebula.

Question

Quizplus · Accepted Answer

Most meteoroids are fragments of asteroids. These are small pieces of rocks that break off from asteroids due to collisions or other processes, and they can enter the Earth's atmosphere and create meteors (shooting stars).

Note: While some meteoroids may be ice chipped off comets (A), and others may be interstellar matter (B), these types are less common than meteoroids from asteroids. Option (D) is incorrect because meteoroids are not typically considered debris from the original solar nebula, as those particles would have merged into larger bodies or been blown away long ago.
