Multiple Choice

Which cloud form is described as a sheet?

Cloud forms reveal their shape and height, and a sheet-like appearance means the cloud forms a broad, flat layer across the sky. That is stratus. Stratus clouds stretch out as a uniform gray sheet, often covering the whole sky and bringing overcast conditions, sometimes with light drizzle or fog at the surface. In contrast, cirrus are high and wispy, cumulus are puffy and bulging, and nimbus refers to precipitation rather than a specific sheet shape (as in nimbostratus or cumulonimbus). So the description of being a sheet fits stratus best.
