Clouds
Clouds are the white formations we see in the sky, located only in the troposphere. They are made from water vapor. Clouds are made up of millions of water droplets and can be made from ice crystals, or water droplets. They are formed when water vapor condenses onto a dust particle. Millions of them come together to form some cloud. For it to rain, the water droplets have to become heavy enough for it to participate from the clouds. Snow is the same way except the temperatures are much colder causing the water droplets to freeze making snow. Clouds are formed when water vapor hits the saturation point. The saturation point is when the air can hold the most amount of moisture it can. Fog is cloud that is formed 50 feet above the ground. Clouds can be formed in other ways. Orographic uplift is when air rises due to a physical object, like mountains, causing the air to cool. This creates clouds. Frontal lifting is when two masses of air collide. The air is two different types. One is cold and dry while the other is warm and moist. The warm air rises above the cold air making it form clouds. Radioactive cooling is at night when the Earth loses energy in radiation making the air cool forming fog. Clouds are categorized into three main categories: cumulus, stratus, and cirrus. Cumulus clouds are puffy white clouds mainly formed below 6,500 feet. Stratus clouds are layered clouds mainly formed below 6,000 feet. Cirrus clouds are strand-like clouds mainly formed above 23,000 feet. If cloud formation is affected by temperature then warmer temperatures will form more clouds because there will be more water vapor in the air for clouds to form on.
