Question

a comet is a
meteoroid that travels through earths atmosphere and hits the surface.
meteoroid that burns up in earths atmosphere, producing a streak of light.
small, rocky object that orbits the sun and is usually found in a belt between the orbits of mars and jupiter.
small object made of ice and dust that orbits the sun and forms a coma as it approaches the sun.

Explanation:

A comet is a small object composed of ice and dust. When it approaches the Sun, the heat causes the ice to vaporize, forming a coma (a fuzzy, glowing envelope around the nucleus). Comets orbit the Sun.

• The first option describes a meteorite (a meteoroid that hits Earth's surface).
• The second option describes a meteor (a meteoroid that burns up in the atmosphere).
• The third option describes an asteroid (small, rocky objects, mostly in the asteroid belt between Mars and Jupiter).

Answer:

small object made of ice and dust that orbits the Sun and forms a coma as it approaches the Sun.
