Final answer:
When condensation occurs near Earth's surface, dew forms on grass and other surfaces.
Step-by-step explanation:
Condensation is a crucial part of the water cycle, where water vapor in the atmosphere cools and changes from a gas to a liquid. When this process of condensation occurs near Earth's surface, dew forms on the grass and other surfaces (option b). This phenomenon can be observed early in the morning as moisture on various surfaces. It is a direct result of water vapor cooling upon coming into contact with cooler surfaces near the ground. Unlike clouds, which form at higher altitudes, dew formation is quite apparent at ground level when conditions are right. While there are many occurrences due to condensation, such as cloud formation or snowfall, the most applicable to the question pointing to what happens at or near the Earth's surface would be the formation of dew.
