Why do clouds float?
Clouds form when warm wet air rises and condenses in cold air.
Water droplets in air behave the same way as dust6.
The second reason that clouds can float in the air is that there is a constant flow of warm air rising to meet the cloud: the warm air pushes up on the cloud and keeps it afloat..
Why are clouds white?
But in a cloud, sunlight is scattered by much larger water droplets. These scatter all colours almost equally meaning that the sunlight continues to remain white and so making the clouds appear white against the background of the blue sky.
Is fog a liquid or gas?
Fog shows up when water vapor, or water in its gaseous form, condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. You can see fog because of these tiny water droplets. Water vapor, a gas, is invisible.
How are clouds formed short answer?
The Short Answer: 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. You hang up a wet towel and, when you come back, it’s dry.
How are clouds formed Class 9?
Ans: During the day time in the presence of sunlight water from sources like well, lake, pond, sea, river and various other sources get evaporated and this water vapour rises up with the hot air. At a particular height, the air cools and the water vapour condenses to form minute droplets to form clouds.
Is fog a cloud?
Clouds can form at many different altitudes. They can be as high as 12 miles above sea level or as low as the ground. Fog is a kind of cloud that touches the ground. Fog forms when the air near the ground cools enough to turn its water vapor into liquid water or ice.
What causes low lying clouds?
The lighter warm air is forced to rise over the cold air mass, leading to cloud formation. The lowering clouds indicate that the front is drawing near, giving a period of rain in the next 12 hours.
Why do clouds turn GREY?
When clouds are thin, they let a large portion of the light through and appear white. But like any objects that transmit light, the thicker they are, the less light makes it through. As their thickness increases, the bottoms of clouds look darker but still scatter all colors. We perceive this as gray.
Why do clouds float for kids?
A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that its made of is warmer than the outside air around it, it floats!
How high can clouds go?
At the upper reaches of the troposphere you’ll find high clouds, which, depending on geographic location, occur between roughly 10,000 and 60,000 feet. Below that is the home of mid-level clouds, which generally occur between 6,000 and 25,000 feet.
How are clouds formed step by step?
Clouds form when moist, warm rising air cools and expands in the atmosphere. The water vapor in the air condenses to form tiny water droplets which are the basis of clouds.
How are clouds formed Class 2?
Clouds are made up of tiny water droplets or ice crystals. The droplets and crystals are very light and they can float in the air. Clouds are formed when warm air rises, expands and then cools. … When billions of these particles come together , they form a cloud.
Can a cloud fall?
Clouds can hold an enormous amount of water. When this water falls as rain it clearly has a significant mass so why don’t clouds fall? In fact, the small water droplets that make up clouds do fall slowly. However, the drag force of the air dominates over the gravitational force for small particles.
How do clouds disappear?
Put simply, clouds develop out of the process of changing moisture from a gas to liquid. This occurs through a process called convection. … Then any cloud droplets tend to evaporate and the cloud itself disappears; evaporation changes moisture back from liquid into gas.
Why do clouds float in the sky Class 11?
FLOATING CLOUDS. The water and ice particles in the clouds we see are simply too small to feel the effects of gravity. As a result, clouds appear to float on air. Clouds are composed primarily of small water droplets and, if it’s cold enough, ice crystals. … So the particles continue to float with the surrounding air.
