1.) are pieces of rock that strike the surface of a moon or planet. a. meteoroids c. meteor showers b. comets d. meteorites

2.)most asteroids are found between the orbits of neptune and uranus. t or f

3.)what happens to a comet after it has made several trips around the sun?

1.) d. Meteorites are pieces of rock that strike the surface of a moon or planet.

2.) False

3.) The comet vaporizes

Explanation:

1.) A moon or a planet is continuously bombarded by space rocks. These are known as meteoroids. The space rocks that burn up in the atmosphere are known as meteor shower. The meteoroids that survive the atmosphere and strike the surface are known as meteorites. These rocks are debris of the celestial bodies.

2.) Asteroids are small  irregular shaped rocky bodies orbiting the sun. Majority of the asteroids are found in the asteroid belt present between the orbits of Mars and Jupiter. Hence, the given statement is false.

3.) A comet is composed of ice, dust and frozen gases. In each round around the sun, comet loses some of its mass because the ice and frozen gases vaporize. Thus, when a comet has made several trips around the sun, it completely vaporizes and the remnant dust remains in the orbit of the comet.
