Which of the following cloud classifications is correctly identified as a mid-altitude cloud layer that typically appears as grey or bluish sheets or patches, often covering the entire sky?

💡 Solution & Explanation

Altostratus clouds form a mid-altitude grey or blue-gray sheet that often blankets the entire sky, letting the sun appear dimly through a translucent veil. Options like Altocumulus consist of patchy, rolled masses rather than a uniform sheet, whereas Cirrostratus are high-altitude ice-crystal clouds that frequently produce halos around the sun.
