Directions: Read the following passage and answer the questions.
"Clouds form when water vapor — an invisible gas in the atmosphere — sticks to tiny floating particles, such as dust, and turns into liquid water droplets or ice crystals. In a newly published study, we show that microplastic particles can have the same effects, producing ice crystals at temperatures 5 to 10 degrees Celsius (9 to 18 degrees Fahrenheit) warmer than droplets without microplastics.
Clouds in the atmosphere can be made up of liquid water droplets, ice particles or a mixture of the two. In clouds in the mid- to upper atmosphere where temperatures are between 32 and minus 36°F (0 to minus 38°C), ice crystals normally form around mineral dust particles from dry soils or biological particles, such as pollen or bacteria.
For freezing to occur at warmer temperatures, some kind of material that won't dissolve in water needs to be present in the droplet. This particle provides a surface where the first ice crystal can form. If microplastics are present, they could cause ice crystals to form, potentially increasing rain or snowfall."
The presence of microplastics in the atmosphere might lead to _______.
