Final answer:
The molecules combine and eventually fall as precipitation.
Step-by-step explanation:
The step in the water cycle that is most likely to happen next as the water molecules in the cloud move through the atmosphere is d. The molecules combine and eventually fall as precipitation. When the water molecules in the cloud cool and condense, they come together to form larger droplets. As these droplets grow in size, they become heavy enough to fall from the cloud as precipitation, such as rain, snow, or hail.
