Question 1202Navigation General

The correct answer is A) altostratus. Altostratus clouds are uniform, grayish-white cloud sheets that cover large portions of the sky and are responsible for a significant amount of precipitation in temperate latitudes. They are classified as middle-level clouds, found at altitudes between 2,000 and 7,000 meters (6,500 to 23,000 feet). The other answer choices are incorrect because: B) Altocumulus clouds are middle-level clouds that appear as a layer of white or gray, rounded masses or rolls. C) Cirrocumulus clouds are high-level, thin, white, and patchy clouds that often have a rippled appearance. D) Cirrostratus clouds are high-level, thin, and sometimes transparent, sheet-like clouds that often cover the entire sky.
