A. Comets are mostly made up of rock. They are usually very easy to see but as they approach the Sun, the rock condenses and becomes much harder to see.
B. Comets are mostly made up of dust particles, frozen water and frozen gases. They are usually very hard to see, but as they approach the Sun, these particles heat up and become much easier to see.
C. Comets are mostly made up of dust particles, frozen water and frozen gases. They are usually very easy to see but as they approach the Sun, these particles condense and become much harder to see.
D. Comets are mostly made up of rock. They are usually very hard to see, but as they approach the Sun, the rock heats up and becomes much easier to see.

B.Comets are mostly made up of dust particles, frozen water and frozen gases. They are usually very hard to see, but as they approach the Sun, these particles heat up and become much easier to see. Step-by-step explanation:

Makes the most since

Answer 2

Answer choice B.

Step-by-step explanation:

Comets are usually made up of ice, dust, and gas, meaning that options A and D are wrong. Also, as a comet approaches the sun, its particles heat up so quickly that they don't have time to become liquid; they turn straight from solid to gas. This makes them very visible when they come near the sun. Therefore, the correct answer is B. Hope this helps!
