Question

Which is not a source of meteoroids?

material from the asteroid belt


leftover interplanetary debris


the solid remains of comets


rocky chunks from neighboring solar systems

Answer 1

It's obviously D. There's no way that anything from another solar system would hit our planet because it wouldn't leave its' galexy's orbit.

Answer 2

Rocky chunks from neighboring solar systems is not a source of meteoroids.

Meteoroids are relatively small (sand to boulder-sized) fragments of rock orbiting the Sun inside the solar system. Meteoroids are usually formed from three main sources which are; (i) the collision of asteroids which produces crumbly debris (meteroids) in the asteroid belt, (ii) the solid remains of comets which occurs due to huge meteor showers and (iii) leftover from the debris that formed the solar system. Rocky chunks from neighboring solar systems is not a source of meteoroids.
