Question

what is a key difference between asteroids and comets? (1 point)
comets are only found in the asteroid belt
asteroids glow when heated
comets are icy and develop tails near the sun
asteroids have orbits that go beyond neptune

Explanation:

Comets are composed mainly of ice, dust, and frozen gases. When they approach the Sun, the heat causes the ice to vaporize, forming a glowing coma and a tail. Asteroids are rocky and metallic objects that do not develop tails near the Sun. Comets are not only found in the asteroid - belt, asteroids don't glow when heated in a notable way like comets near the Sun, and most asteroids are in the asteroid - belt between Mars and Jupiter, not beyond Neptune.

Answer:

C. Comets are icy and develop tails near the Sun
