Final answer:
Cloud, fog, and dew formation are related to the dew-point and humidity. When air becomes saturated, clouds, fog, or dew may form depending on the conditions.
Step-by-step explanation:
The concepts of cloud, fog, and dew formation are related to the dew-point and humidity. Dew-point is the temperature at which air becomes saturated, meaning it cannot hold any more water vapor, and starts to condense into liquid water. Humidity refers to the amount of water vapor present in the air. When the dew-point is reached, clouds, fog, or dew can form depending on the conditions.
Clouds are formed when warm, moist air rises and cools, causing the water vapor to condense into tiny water droplets or ice crystals. Fog is a type of cloud that forms near the ground when the air becomes saturated, often due to cooling or mixing of moist air. Dew forms when the temperature of a surface, such as grass or leaves, drops below the dew-point, causing the water vapor in the air to condense into liquid droplets.
