Final answer:
Clouds are indeed classified based on their form and color, a true statement that applies to both Earth and other planets like Jupiter and Saturn. Cloud classification helps us understand atmospheric structures and weather phenomena.
Step-by-step explanation:
The statement that clouds are classified on the basis of their form and color is true. In the case of extraterrestrial clouds, such as those on Jupiter, they exhibit a stunning array of colors from white to orange to red to brown, and they change patterns dynamically. On Saturn, the cloud activity is more uniform, displaying a butterscotch hue. Even on Mars, several types of clouds are present: dust clouds, water-ice clouds, and CO₂ clouds, the last of which has no counterpart on Earth due to temperature differences.
Back on Earth, clouds are also classified based on their appearance and altitude. For instance, high clouds like cirrus are thin and wispy, while lower clouds such as stratus are typically gray and cover the sky like a blanket. The beautiful hues we observe during sunsets and sunrises are phenomena where clouds reflect sunlight, creating vibrant scenes. Our understanding of clouds helps us comprehend the atmospheric structure and weather patterns both on our planet and across the solar system.
