Which mid-level cloud forms in a light sheet that can allow sunlight to pass while not presenting a distinct sun spot?

• A. Cirrocumulus
• B. Altocumulus
• C. Altostratus
• D. Nimbostratus

Answer: (C)

Mid-level clouds form a uniform veil across the sky. Altostratus appears as a light gray to bluish sheet that sits at mid altitude, often dimming the sun but not revealing a distinct sun spot. The sun is visible only as a hazy disk through the milky layer, which is why you don’t see a clear sun. This contrasts with cirrocumulus, which are high, small patches; altocumulus, which are patchier and often show individual cloudlets; and nimbostratus, which is a thick, dark layer that typically blocks the sun and brings precipitation.
