Answer:
Options (2), (3) and (5)
Step-by-step explanation:
Clouds are usually defined as a large accumulation of small water droplets or crystals of ice. These droplets are so light and small that they can easily float in the air. They are found to be present in both the upper and the lower atmosphere, or near the ground surface, occurring in different shapes and patterns. Clouds that are formed near the earth's surface are commonly known as fogs.
When warm and moisture containing water rises upward, it cools and slowly starts to condense, and turns into smaller particles. This results in an increase in the relative humidity of the air.
Thus, the correct answers are options (2), (3) and (5).
