 * __HOW FAST DO CLOUDS MOVE AND HOW LONG DO CLOUDS LAST?__**

Answer the question below, append new answers to the top of this page. _ __Response 1:__ How Long Do Clouds last you say? Let's take it back to when we were learning about clouds. As we all know, there are many types of clouds that have different abilities. Stratus Clouds (Low Clouds): These clouds are grey and often covers the entire sky, but never reach the ground like a fog would. These clouds may rain, but can only drizzle down. These clouds are created due to thick fogs being lifted into the sky. Alto Clouds (Middle Clouds): Alto Clouds are made up of water droplets and appear as grey, puffy masses but can also appear as rolled up clouds like parallel waves. If you bother to see this type of cloud on a humid day, this will tell you that a thunderstorm may appear later on in the day. Cirrus Clouds (High Clouds): Cirrus Clouds are clouds that appear as wispy and thin as wind streams blow into them. When you see them, this will mean that the weather will be pleasant. Cumulus Clouds (Clouds with Vertical): These clouds looks like floating cotton in the sky, where the top of this cloud has rounded towers. This cloud can be a sign of thunderstorms, and if it builds higher, it becomes Cumulonimbus Clouds. These Clouds are way more powerful than Cumulus and can cause lightning, thunderstorms and even violent tornadoes. How do these clouds form anyways? Clouds are formed by tiny water droplets and ice crystals. Now of course you know that water can have many stages, such as forming into a solid, then a liquid, to a gas, and then it starts all over again. When the tiny droplets are suspended into the air, they can create clouds. If the droplets can become larger, they will make the cloud more visible like fog. After they have formed into these kind of clouds, it will rain or snow after. All this information I am using will find me the answer of how clouds disappear. Since clouds are made of water droplets and ice particles inside, clouds can warm up and turn into **Water Vapor.** Water Vapor is a transformation of a cloud when it is hot, and is still in the sky, just not as visible as you might think. If the water vapour is in very cold weather or is very chilled up by the weather, clouds will start to form again.

How Fast do Clouds Move? Well, the environmental wind creates the shapes of some Cirrus Clouds, and that's how they travel. The wind pushes the poofy clouds across the sky. Cirrus Clouds can travel 100 miles per hour, while thunder clouds like Cumulus can travel around 30 to 40 miles per hour. The wind is what keeps the atmosphere moving as many things float in the sky. So pretty much, clouds move as fast as...well...how fast the wind moves.

 * Water Vapor:** Water Vapor is the gas-state of water and can usually be found in steam.
