Hi bloggers👋 for writing i did how do clouds form this topic is about how do clouds from and what are clouds after you have choose your topic you have find 3 text to get information then you have to put your information in a skinny note after that you have to use a hamburger plan to make your explanation writing.
Here is my work:
Have you ever looked at a fluffy cloud and wondered how they form? Clouds are created when water vapor, an invisible gas, turns into liquid water droplets. These water droplets form on tiny particles, like dust, that are floating in the air.
Clouds appear when there is too much water vapor for the air to hold. The water vapor (gas) then condenses to form tiny water droplets (liquid), and it is the water that makes the cloud visible. These droplets are so small that they stay suspended in the air.
As a simple explanation, when the air rises, it cools, much like when you are going up a mountain and the air tends to get colder. Cold air can’t hold as much water vapor than warm air can, so as the air cools, it becomes saturated and the water vapor in it condenses. This means it turns from a gas to a liquid, much like when you get condensation on a cold window. When the water vapor turns to a liquid in the sky, it forms lots of tiny little water droplets which cling to little bits of dust; it is this group of little water droplets suspended in the air that becomes visible as the cloud we see.
These droplets of water are only about a hundredth of a millimeter in diameter, but the cloud is made up of a large collection of these. If the cloud is high up enough in the sky and the air is cold enough, the cloud is made of lots of tiny ice crystals instead and gives a thin, wispy appearance.
There is also the fact that a cloud can form when more water vapor has been added to the air, for example if it has passed over a lake, it can pick up moisture. There is then more water vapor in that air and it condenses to form the cloud.
The air can only hold a certain amount of water vapor, depending on the temperature and weight of the air – or atmospheric pressure – in a given area. The higher the temperature or atmospheric pressure, the more water vapor the air can hold. When a certain volume of air is holding all the water vapor it can hold, it is said to be “saturated.”
What happens if a saturated volume of air cools or the atmospheric pressure drops? The air is no longer able to hold all that water vapor. The excess amount changes from a gas into a liquid or solid (ice). The process of water changing from a gas to a liquid is called “condensation,” and when gas changes directly into a solid, it is called “deposition.” These two processes are how clouds form.
Condensation happens with the help of tiny particles floating around in the air, such as dust, salt crystals from sea spray, bacteria or even ash from volcanoes. Those particles provide surfaces on which water vapor can change into liquid droplets or ice crystals.
