Hence, the role of the ocean in the climate system is fundamental, requiring that close attention should be paid to it. The water vapour is transported by the ascending air currents to altitudes where low temperatures condense the steam into water droplets or ice crystals that form clouds.

Where do clouds come from?
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.
Are clouds 100% water?
Clouds are not 100 percent water. They also contain salt, dust, and other particles and chemical substances. There are ten different types of clouds, and each one can provide valuable information about current and future weather conditions.
Are clouds made of salt water?
One naturally occurring process that plays a big role in this delicate balance is the formation of clouds. Clouds are made of tiny droplets of water. It has long been known that the droplets that make up clouds form around tiny nuclei — grains of dust, salt or even microbial life.
Where do clouds go at night?

Can a cloud fall?
Even though a cloud weighs tons, it doesn’t fall on you because the rising air responsible for its formation keeps the cloud floating in the air. The air below the cloud is denser than the cloud, thus the cloud floats on top of the denser air nearer the land surface.
Can you touch clouds?
Unfortunately, it does not feel like cotton balls or cotton candy, but most people have technically touched a cloud before. If you wanted to touch an airborne cloud, the best way to do this is either skydiving or in a hot air balloon, though I would not want to be stuck in a cloud while in a hot air balloon.
Why do clouds not fall to the ground?
So, even though typical clouds do contain a lot of water, this water is spread out for miles in the form of tiny water droplets or crystals, which are so small that the effect of gravity on them is negligible. Thus, from our vantage on the ground, clouds seem to float in the sky.
Are clouds gas or liquid?
The water that makes up clouds is in liquid or ice form. The air around us is partially made up of invisible water vapor. It’s only when that water vapor cools and condenses into liquid water droplets or solid ice crystals that visible clouds form.
Are clouds cold or hot?
Clouds consist of microscopic droplets of liquid water (warm clouds), tiny crystals of ice (cold clouds), or both (mixed phase clouds).
How heavy is a cloud?
According to scientists, the weight of the average cumulus cloud is 1.1 million pounds! Think about that for a moment. This means that at any given moment, there are millions of pounds of water floating above your head.
Can clouds run out of rain?
After raining all day, why don’t they “run out” of water? Straight off, the answer is that they are constantly resupplying themselves with new moisture and water all the time in the form of rising air. In order for a cloud to form, you need to have rising air.
How do clouds disappear?
The three primary ways that clouds dissipate is by (1) the temperature increasing, (2) the cloud mixing with drier air, or (3) the air sinking within the cloud. When the temperature increases, the air has a higher capacity to evaporate liquid water.
Why are clouds white?
Clouds are white because light from the Sun is white. As light passes through a cloud, it interacts with the water droplets, which are much bigger than the atmospheric particles that exist in the sky.
Why do clouds disappear at sunset?
“Typically, fair-weather cumulus clouds dissipate a few hours after sunset because their lifeblood, the contrast of the warm ground and the cooler air aloft, has been cut off,” he said. The atmosphere is least stable in the afternoon, with the freest exchange of air from low levels to high.
Can a cloud freeze?
When the water drops get high enough in the sky, they encounter the colder temperatures at higher altitudes and freeze, even in the summer. Both water drops and ice crystals in a cloud are so small that they both look like white fluff from the ground.
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.
Can air be pulled down by gravity?
Although air is very tenuous compared to other materials, it is indeed composed of atoms and indeed has mass. As such, air is pulled down by gravity just like everything else that has mass.
Why do clouds move?
Clouds move because the wind is carrying the parcel of cloudy air along. Wind occurs at all levels of the atmosphere from the ground up to higher than a jumbo jet can fly. Sometimes there can be no wind on the ground, but cirrus clouds very high up can be seen moving because of the wind where they are.
What happens when clouds touch 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. There are many different types of fog, too. Ice fog forms when the air near the ground is cold enough to turn the water in fog into ice crystals.
How do clouds stay floating?
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.
Can you put a cloud in a jar?
Can you make a cloud in a jar? Absolutely! With just a few things from around the house you can simulate the conditions needed for clouds to form.
Can you eat clouds?
As clouds are made up of water vapor and helium, they are not harmful to eat. While eating clouds isn’t exactly harmful, it certainly isn’t nutritious.
Can we touch rainbow?
A rainbow is nothing more than scattered light from the sun. When it rains and the sun shines simultaniously the raindrops act like a prism, refracting the light so that a spectrum appears in the sky. In other words, a rainbow is an optical illusion which cannot be physically touched nor approached.
Are clouds made of ice?
A cloud is made of water drops or ice crystals floating in the sky.
What freezes inside a cloud before it falls?
Hail forms in cold storm clouds. It forms when very cold water droplets freeze, or turn solid, as soon as they touch things like dust or dirt. The storm blows the hailstones into the upper part of the cloud. More frozen water droplets are added to the hailstone before it falls.
Is a cloud a living thing?
For young students things are ‘living’ if they move or grow; for example, the sun, wind, clouds and lightning are considered living because they change and move.
Can we create a cloud?
In this activity, you can make your own cloud to see for yourself! Clouds form from the condensation or freezing of water vapor. Condensation is the process of a gas changing into a liquid. In this activity, the gas is water vapor and the liquid is the cloud you create.
Why does rain fall from clouds?
Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth. If a cloud is colder, like it would be at higher altitudes, the water droplets may freeze to form ice.
Can a cloud hold a person?
Clouds are made of millions of these tiny liquid water droplets. The droplets scatter the colors of the sunlight equally, which makes clouds appear white. Even though they can look like cushy puffballs, a cloud can’t support your weight or hold anything up but itself.
Can you breathe in clouds?

What happens if you go into a cloud?
So, what happens if you skydive through a cloud? Well, it could be that nothing happens, or the consequences could be catastrophic. As you probably recall from middle school science, in essence, clouds are condensed water vapor, much like fog. Analogously to fog, within a cloud, visibility is significantly reduced.
What was the largest cloud ever recorded?
Astronomers have discovered the largest and oldest mass of water ever detected in the universe — a gigantic, 12-billion-year-old cloud harboring 140 trillion times more water than all of Earth’s oceans combined.
Why is the sky blue for kids?
White light is made up of all colors of light. Nitrogen molecules scatter blue light more than they do the other colors. So a little bit of blue light bounces around in the sky and then enters our eyes. That makes the sky look blue.
How do you explain clouds to kids?
Technically, clouds are a massive collection of tiny ice crystals or water droplets — so tiny, they float way up in the air. But for your students, clouds are more than just dust and water. They’re mysterious, puffy objects that wander through the sky and constantly change into endless, wonderful shapes.
Why the clouds are black?
White is how our eyes perceive all wavelengths of sunlight mixed together. When it’s about to rain, clouds darken because the water vapor is clumping together into raindrops, leaving larger spaces between drops of water. Less light is reflected. The rain cloud appears black or gray.
What are nimbus clouds?
The nimbus clouds are the rain clouds that belong to the category of low-level clouds. The word nimbus in Latin means rainstorm clouds that are found at the lowest altitude of 8000 ft (2400 m), and are usually large grayish-black clouds that cover the entire sky.
How long does cloud water last?
A drop of water may spend over 3,000 years in the ocean before evaporating into the air, while a drop of water spends an average of just nine days in the atmosphere before falling back to Earth.
Why does it rain all at once?
The rain doesn’t dump all it’s water at once because: Inside the cloud, it always rains. Water vapor rises from the bottom of the cloud to the top, condenses and falls back to the bottom of the cloud, where it (mostly) vaporizes again and repeats this cycle.
Are there clouds in sun?
The Sun hosts many different phenomena. One of those- filaments- may resemble dark clouds, but they are nothing like the clouds on Earth, writes Dr. Christoph Kuckein from the Leibniz-Institut für Astrophysik Potsdam (Germany).
What do clouds do during the night?
At night, when there’s no sunlight, clouds are still trapping heat. It’s sort of like clouds are wrapping Earth in a big, warm blanket. So clouds can have both a cooling effect and a warming effect.
Why do clouds come and go?
Sometimes air goes up past the condensation level then falls back below the condensation level, then up, then below, again and again. This creates clouds that are stripy, often with lines between the clouds. The way the air moves creates all the different clouds we see.
What is the cloud burst?
cloudburst, a sudden, very heavy rainfall, usually local in nature and of brief duration. Most so-called cloudbursts occur in connection with thunderstorms. In these storms there are violent uprushes of air, which at times prevent the condensing raindrops from falling to the ground.
Where do clouds go when the sky is clear?
So, Do Clouds Really Disappear? No, they don’t. They just evaporate and become invisible water vapor. The micro-droplets of water become another form or water.
Do clouds have dust in them?
They compared their results with analyses from the onboard mass spectrometer and found the two datasets revealed very similar cloud profiles: More than 60 percent of cloud particles consisted of mineral dust blown into the atmosphere, as well as metallic aerosols.
Why do clouds look fluffy?
When warm air rises from the ground, it carries water vapor with it. When the water vapor meets the cold air found high in the sky, the gas condenses to liquid and forms cumulus clouds. While these fluffy-white clouds look like soft pillows of cotton, they are actually composed of small water droplets.
What happens when the tiny water particles get cold?
When the water vapor cools enough, the attractions between the molecules bring them together. This causes the water vapor to change state and become tiny drops of liquid water. The process of changing from a gas to a liquid is called condensation.
Why are clouds white 10?
All the suspended particles in cloud have size very larger than the wavelength of visible light falling onto it. So, it suffers almost zero scattering. Hence the clouds which have droplets of water with a>>λ are generally white.
Why are clouds pink?
Excess dust and aerosols suspended in the atmosphere diffuse and scatter light and only the longer wavelength light remains, making the clouds appear pink color or a pinkish-red sky at night.
Why do clouds turn green?
“Those are the kind of storms that may produce hail and tornadoes.” Green does indicate that the cloud is extremely tall, and since thunderclouds are the tallest clouds, green is a warning sign that large hail or a tornado may be present.
Where does Earth’s gravity end?
The Earth’s gravitational field extends well into space it does not stop. However, it does weaken as one gets further from the center of the Earth. The Shuttle orbits about 125 mi above the surface, roughly the distance between Jackson and Nashville!
What holds the Earth in place?
The force that physically holds the world’s interior together is the Earth’s gravitational pull, commonly known as gravity. Sir Isaac Newton described it for the first time in his law of gravity. Gravity is one of the reasons why everything falls to the ground and is held there as if by a magnet.
Why is there no air in space?
This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. ‘Outer space’ begins about 100 km above the Earth, where the shell of air around our planet disappears. With no air to scatter sunlight and produce a blue sky, space appears as a black blanket dotted with stars.
Can a cloud fall?
Even though a cloud weighs tons, it doesn’t fall on you because the rising air responsible for its formation keeps the cloud floating in the air. The air below the cloud is denser than the cloud, thus the cloud floats on top of the denser air nearer the land surface.
Can you feel a cloud?
