All air contains water, but near the ground it is usually in the form of an invisible gas called water vapor. When warm air rises, it expands and cools. Cool air can't hold as much water vapor as warm air, so some of the vapor condenses onto tiny pieces of dust that are floating in the air and forms a tiny droplet around each dust particle. When billions of these droplets come together they become a visible cloud.

1. Cumulus clouds are puffy clouds that sometimes look like pieces of floating clotting ball.

2. They are off in about only 1000 m (330 ft) above the ground.

3. and they can develop into a giant cumulonimbus, which is a thunderstorm cloud.

1.
Stratus clouds are uniform grayish clouds that often cover the sky. They resemble fog that doesn't reach the ground. Light mist or drizzle sometimes falls out of these clouds.

2. They are about 6,500 feet off the ground

3. These cloud are uniformed but they produce mist drizzle of tiny rain drop.they look lick wave on a ocean.

1. Cirrus clouds are the most common of the high clouds,they are composed of ice and are thin, wispy clouds blown in high winds into long streamers.

2. Cirrus clouds are usually white and predict fair to pleasant weather,by watching the movement of cirrus clouds you can tell from which direction weather is approaching.

3. When you see cirrus clouds, it usually indicates that a change in the weather will occur within 24 hours.and is offing about 3,000 ft in. the atmosphere

Essentially, fog is a cloud that occurs at ground level instead of in the sky. Fog is made up of tiny droplets of water that float suspended in the air, but it also may consist of ice particles during very cold conditions. Under most circumstances, air contains water vapor. The warmer the air, the more water it can hold. As the air cools, it loses its ability to hold that water. When the air cools to the so-called dew point, it becomes fully saturated with water vapor. If the air cools any further, it loses the ability to hold all of that water vapor and forces some of the vapor to condense around microscopic particles, like dust, forming droplets. When enough of these droplets form, fog is made
