Which cloud is described as a low, flat layer that covers the sky?

• A. Cirrus
• B. Altostratus
• C. Stratus
• D. Stratocumulus

Answer: (C)

Clouds are categorized by where they form in the atmosphere and how they look. Stratus clouds are the ones that form a low, uniform, gray sheet that covers the whole sky. They sit near the ground or low in the troposphere and give an overcast appearance, often bringing light rain or drizzle. That flat, blanket-like layer is what sets them apart. Cirrus clouds are high and wispy, made of ice crystals, and don’t blanket the sky. Altostratus clouds are mid-level gray sheets that cover the sky but aren’t as uniformly flat or blanket-like. Stratocumulus form a low, lumpy layer with breaks, so they don’t produce the same smooth, featureless sheet as stratus.
