This stack shows you what type of clouds are which.

Cirrus Clouds form in cold air at very high altitudes; made of ice crystals and have a wispy or feathery appearance; mean fair weather, but can be a sign that a storm is approaching
Cumulus Clouds puffy, white, and look like cotton balls; are a sign of fair weather; however as they continue to grow taller and darken at the bottom, they can produce thunder showers (become cumulonimbus clouds)
Stratus Clouds smooth, layered. and block out the sun, causing the entire sky to look gray; produce steady, light precipitation
Fog a cloud that rests on the ground or a body of water; forms when a surface is colder than the air above it. It clears as the ground is heated up by sunlight.
