Answer to Question 1

Most comets reside in the Oort cloud and the Kuiper belt in the outer reaches of the solar system. Eventually, comets lose their snowball material from burning up in tails and comas near the Sun and then continue to orbit as asteroid-like bodies.

Answer to Question 2

(1) Interplanetary debris that did not get incorporated by the planets during the formation of the solar system
(2) Material being ejected from the asteroid belt
(3) The rocky and/or metallic remains of comets that once passed through Earth's orbit
