Correct Answer
B. Stratus
Explanation
Stratus clouds are low-level clouds that appear as a uniform layer covering the sky. They are typically gray or white in color and often bring drizzle or light rain. Unlike cumulus clouds, which are puffy and have a vertical development, stratus clouds are flat and do not have any significant vertical extent. Nimbostratus clouds, on the other hand, are similar to stratus clouds but bring continuous rain or snow. Cirrocumulus and cirrostratus clouds are high-level clouds that form at higher altitudes and have a different appearance than stratus clouds.
2.
Correct Answer
A. Cumulus
Explanation
Cumulus clouds are large, white, and fluffy with a flat base and rounded tops. They are often associated with fair weather but can also develop into towering cumulonimbus clouds, which bring thunderstorms. Stratocumulus clouds are low-level clouds that appear as a layer or patchy sheet with a wavy or lumpy appearance. Stratus clouds are low-level, uniform, and featureless clouds that often cover the entire sky, creating a gray or overcast appearance. Cirrus clouds are high-level clouds that are thin, wispy, and often appear as white streaks or filaments. Altostratus clouds are mid-level clouds that are gray or blue-gray and often cover the entire sky, blocking out the sun but not producing precipitation.
3.
Correct Answer
C. Altocumulus
Explanation
Altocumulus clouds are mid-level clouds that are typically composed of water droplets and appear as white or gray patches or layers. They are characterized by their rounded or wavy shape and can often be seen in groups or rows. Altocumulus clouds are usually found at altitudes of 6,500 to 20,000 feet and are often associated with fair weather. They are different from other types of clouds mentioned in the list such as cumulus, stratocumulus, cumulonimbus, and cirrus, which have their own distinct characteristics and appearances.
4.
Correct Answer
C. Altostratus
Explanation
Altostratus is the correct answer because it is a type of cloud that forms at middle altitudes, typically between 6,500 and 20,000 feet. It appears as a uniform gray or blue-gray layer that often covers the entire sky. Altostratus clouds are thicker than cirrostratus clouds but thinner than nimbostratus clouds. They often indicate the approach of a warm front and can bring steady, light precipitation.
5.
Correct Answer
E. Cirrocumulus
Explanation
Cirrocumulus is the correct answer because it is a type of cloud that is high in the atmosphere, typically found at altitudes above 20,000 feet.

C. Cirrostratus
Explanation
Cirrostratus is a type of high-level cloud that appears as a thin, whitish veil covering the sky. It is composed of ice crystals and is often associated with approaching warm fronts. Cirrostratus clouds are known for their ability to produce a halo effect around the sun or moon due to the refraction of light. They can also indicate the possibility of precipitation in the near future.
10.
Correct Answer
C. Cirrostratus
Explanation
Cirrostratus is a type of high-level cloud that appears as a thin, whitish veil covering the sky. It is often characterized by its fibrous or wavy appearance. Cirrostratus clouds are composed mainly of ice crystals and can indicate the approach of a warm front. They are known for creating a halo effect around the sun or moon due to the refraction of light. Cirrostratus clouds are higher in altitude than altostratus and altocumulus clouds, and they have a different appearance compared to cumulus clouds.
11.
Correct Answer
A. Altocumulus
Explanation
Altocumulus clouds are mid-level clouds that are characterized by their white or gray puffy appearance. They are often arranged in rows or patches and can cover large areas of the sky. Altocumulus clouds are formed by the rising of moist air, which then condenses and forms water droplets or ice crystals. These clouds are usually associated with fair weather conditions, but can also indicate the approach of a warm front or a thunderstorm. Overall, altocumulus clouds are a common and visually appealing type of cloud formation.
12.
Correct Answer
E. Cumulus
Explanation
Cumulus clouds are large, white, and fluffy with a flat base and a rounded top. They are formed by the upward movement of warm air and indicate fair weather. Cumulus clouds are often seen on sunny days and are associated with pleasant conditions. They do not produce precipitation, unlike nimbostratus clouds, which are thick and gray and bring steady rain. Altocumulus and stratocumulus clouds are mid-level and low-level clouds respectively, while stratus clouds are low-level clouds that form a uniform layer and often bring drizzle or light rain.
13.
Correct Answer
D. Stratocumulus
Explanation
Stratocumulus is the correct answer because it is a type of low-level cloud that appears as a layer of patches or rolls. It is usually gray or white in color and can cover a large portion of the sky. Stratocumulus clouds are often associated with fair weather, but they can also bring light rain or drizzle. They are lower in altitude compared to cumulus, altocumulus, and cirrocumulus clouds, and they have a distinct appearance with a flat base and rounded tops. Nimbostratus, on the other hand, is a different type of cloud that is associated with continuous rain or snowfall.
