### Understanding Cloud Formation Cloud Condensation Nuclei (CCN) are tiny particles, including dust and salt, which float around in the atmosphere. These small particles play a critical role in the formation of clouds. #### Diagram Explanation: The provided diagram includes illustrations of water molecules attaching to different types of nuclei. There are three detailed illustrations in the diagram: 1. **Water Molecule with Dust** 2. **Water Molecule with Salt** 3. **Water Molecule Cluster** **Key:** - The water molecules are shown as small spherical shapes. - Salt particles are depicted as cubic shapes. - Dust particles are represented by uneven, irregular shapes. These nuclei serve as surfaces on which water vapor can condense. Without the presence of these particles, it would be significantly harder for clouds to form, as pure water vapor needs a surface to form droplets. ### Activity: **3. Analyze and Explain the Role of Cloud Condensation Nuclei:** Cloud Condensation Nuclei (CCN) are essential for cloud formation because they provide surfaces for water vapor to condense and form droplets. These droplets coalesce to form clouds. Without CCN, cloud formation would be inefficient because water vapor alone lacks the surfaces required to form droplets efficiently. **Your Answer:** --- ### Atmospheric Diagram: The diagram below illustrates an area of air that is rising into the atmosphere to form clouds. - **Height Level:** 6000 feet - Temperature: 60°F - Dew Point: 60°F This indicates that the air at 6000 feet has reached its dew point temperature, meaning the air is fully saturated with moisture and condensation will begin, leading to cloud formation. #### Diagram Details: The diagram is a rectangular box that shows: - A cloud icon at the 6000 feet mark. - Temperature and dew point data is both indicated to be 60°F. - Atmospheric pressure is represented along a vertical axis. This visualization shows the relationship between altitude, temperature, dew point, and atmospheric pressure, illustrating how clouds form in ascending moist air. By analyzing these diagrams and understanding the concepts, one can better grasp the fundamental processes involved in cloud formation and the atmospheric conditions necessary for it.
