Which type of cloud is characterized by a wispy appearance?

The type of cloud characterized by a wispy appearance is the cirrus cloud. Cirrus clouds are high-altitude clouds that form from ice crystals, which gives them their delicate, thin, and wispy texture. These clouds typically appear white and are often seen in fair weather, although they can also indicate that a change in the weather may be approaching. Their altitude and formation process make them distinct from other cloud types, which have different shapes and characteristics based on their altitude and moisture content.

For instance, cumulus clouds are puffy and dense, often appearing like cotton balls; stratus clouds are layered and blanket-like, covering the sky like a thin veil; and nimbus clouds are associated with precipitation and are typically darker and thicker. Each type of cloud has unique features, but the wispy form of cirrus clouds is what makes them easily identifiable in the sky.
