Read the following paragraph and then answer the questions.

Have you ever wondered what would happen if there was less dust. We would be much

happier if there was less dust. However, without it, there would be less rainfall and sunsets

would be less beautiful. Rain is formed when water molecules in the air collect around

particles of dust. When collected water becomes heavy enough, water droplets fall to Earth as

rain. Thus water vapor would be much less likely to turn to rain without dust particles.

The water vapor and dust particles also reflect the rays of the sun. At sunrise and sunset,

when the sun is below the horizon, the dust and water vapor molecules reflect the longer, red

rays of light in such a way that we can see them for more time. The more dust particles in the

air, the more colorful the sunrise or sunset.
