List one or more key identifying features for each of the ten basic cloud types. Which cloud types might have fairly similar appearances and thus be difficult to identify?

Hail is usually associated with ____ clouds.

When surfaces such as twigs, leaves, and blades of grass cool below the saturation temperature, water vapor begins to condense upon them, forming tiny visible specks of water called ____________________. If the air temperature should drop to freezing or below, the ____________________ will freeze, becoming tiny beads of ice called ____________________.
