Clouds are technically part of both the atmosphere and the hydrosphere . The hydrosphere is all of the water on planet Earth.
Why is a cloud part of the atmosphere?
When air rises in the atmosphere it gets cooler and is under less pressure. When air cools, it’s not able to hold all of the water vapor it once was. Air also can’t hold as much water when air pressure drops. The vapor becomes small water droplets or ice crystals and a cloud is formed.
Are clouds in our atmosphere?
Clouds generally form within the troposphere , or the layer of atmosphere closest to the earth. As they rise and fall, they may appear in infinite variations.
How can the atmosphere be considered part of the hydrosphere?
Explain how water vapor could be considered part of the atmosphere as well as part of the hydrosphere: Water vapor is considered part of the hydrosphere because it’s water . It exists in the atmosphere it is understandable to consider it part of that as well.
How will you differentiate a cloud from a sky?
is that cloud is to become foggy or gloomy , to become obscured from sight while sky is (sports) to hit, kick or throw (a ball) extremely high.
In which part of the atmosphere does rain clouds develop?
The lowest portion of the atmosphere is the troposphere, a layer where temperature generally decreases with height. This layer contains most of Earth’s clouds and is the location where weather primarily occurs.
Where do clouds go?
The clouds become saturated with the water droplets, and this causes larger droplets to form. Once the droplets are heavy enough to overcome the convection currents keeping them in the air, they fall to Earth as rain .
How do clouds form in the sky?
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals . For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.
On which part of the atmosphere is the area of Aurora and satellites?
The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. Aurora and satellites occur in this layer.
What things are part of the atmosphere?
We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet . Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. Water vapor and dust are also part of Earth’s atmosphere.
Are clouds gas or liquid?
The cloud that you see is a mixture of solids and liquids. The liquid is water and the solids are ice, cloud condensation nuclei and ice condensation nuclei (tiny particulates that water and ice condense on). The invisible part of clouds that you cannot see is water vapor and dry air.
How do you classify clouds?
Clouds are classified according to their height above and appearance (texture) from the ground . The following cloud roots and translations summarize the components of this classification system: 1) Cirro-: curl of hair, high; 2) Alto-: mid; 3) Strato-: layer; 4) Nimbo-: rain, precipitation; and 5) Cumulo-: heap.
Which of the following is a part of hydrosphere?
Answer: The hydrosphere is the part of a planet that’s made of water. Oceans,rivers,lakes,and clouds are all typically included in the hydrosphere.
Why do clouds float?
Clouds do exist, and they do float in the air . ... The warm, moist air is less dense than the cold air above it, so that warm air rises 2 . The warm air cools as it comes into contact with the cooler air above. Cold air cannot hold as much moisture as warm air: the vapor has to condense into a liquid.
Where did clouds go in summer?
As this air meets the cooler air above it, the moisture condenses out as tall, billowing clouds. In summer, when the sun is highest in the sky, heating of the ground is greater than at other times of year, this creates the biggest temperature gradients between air near the ground and the air above it.
Do clouds move or the earth?
Clouds and the atmosphere generally move with Earth’s rotation . Due to friction with Earth’s surface, the atmosphere and clouds in it are carried along with Earth’s spin. That’s why, for example, the clouds don’t move at 1,000mph over the equator, which spins at 1,000mph.
Does rain make clouds go away?
The other mechanism is by evaporation, in which the cloud droplets themselves are transformed from tiny liquid water droplets into invisible water vapor molecules. ... Original question from Bill Bevan: After a storm the clouds go away .
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. ... Some clouds, like the lenticular clouds that form over hills, are stationary even when the wind is strong.
What happens to clouds after it rains?
When it’s about to rain, clouds darken because the water vapor is clumping together into raindrops , leaving larger spaces between drops of water.
What holds clouds together?
In other words, cold air cannot hold as much water vapor as warm air. Invisible particles in the air in the form of pollution, smoke, dust or even tiny particles of dirt help form a nucleus on which the water molecules can attach. When these droplets come together, they form a cloud.
Which layer of the atmosphere is free from cloud?
The correct answer is (C) Stratosphere . Clouds are formed when the presence of invisible water vapour in the air condenses into visible water droplets. The stratosphere is the second layer of the atmosphere, which is dry and comprises very little water vapour, because of which stratosphere is free from clouds.
What layer of the atmosphere does weather occur?
Troposphere . Known as the lower atmosphere almost all weather occurs in this region. The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20 km) high. The height of the troposphere varies from the equator to the poles.
In which layer do auroras eg Northern Lights occur?
The aurora (Northern Lights and Southern Lights) mostly occur in the thermosphere . The thermosphere is a layer of Earth’s atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet.
What part of the atmosphere do we live in?
The Troposphere
This is the layer we live in and contains most of what we consider to be “the atmosphere,” including the air we breathe and nearly all of the weather and clouds we see. In the troposphere, the temperature of the air decreases the higher you go.
What are the five layers of the atmosphere?
Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere . Troposphere.
What are examples of atmosphere?
Atmosphere is defined as the area of air and gas enveloping objects in space, like stars and planets, or the air around any location. An example of atmosphere is the ozone and other layers which make up the Earth’s sky as we see it. An example of atmosphere is the air and gases contained inside a greenhouse .
Are clouds pure water?
While it’s true that clouds contain water , they actually aren’t made of water vapor. ... 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.
How does a cloud fill up with water?
The water drops and ice crystals that make up a cloud are floating not because they are soaked up by some sponge-like material that is holding them in place. Rather, the water drops and ice crystals that make up a cloud float because they are so small that the air resistance balances out gravity.
How do clouds make water?
Within a cloud, water droplets condense onto one another , causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain. ... Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice.
What is atmosphere short answer?
Atmosphere is the thin layer of air that surrounds the earth . It is made up of various gases such as oxygen, nitrogen, carbon dioxides, dust particles and water vapour. The gravitational force of the earth holds the atmosphere around it. It protects us from harmful rays and scorching heat of the sun.
What is Earth’s atmosphere?
An atmosphere is the layers of gases surrounding a planet or other celestial body . Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
What are the 4 levels of clouds?
- Cirro-form. The Latin word ‘cirro’ means curl of hair. ...
- Cumulo-form. Generally detached clouds, they look like white fluffy cotton balls. ...
- Strato-form. From the Latin word for ‘layer’ these clouds are usually broad and fairly wide spread appearing like a blanket. ...
- Nimbo-form.
Are clouds more likely to form on the windward or leeward side of mountains Why?
As the wind blows across a mountain range, air rises and cools and clouds can form on the windward side. This is why windward sides of mountain ranges tend to get heavy precipitation . When the air sinks on the leeward side of the mountain range, it is usually much drier and warmer than it was to begin with.
Which cloud is highest in atmosphere?
- Noctilucent clouds, or night shining clouds, are tenuous cloud-like phenomena in the upper atmosphere of Earth. ...
- They are the highest clouds in Earth’s atmosphere, located in the mesosphere at altitudes of around 76 to 85 km (249,000 to 279,000 ft).
Can you physically touch a cloud?
Well, the simple answer is yes , but we will get into it. Clouds look like they would be fluffy and fun to play in, but they are actually made of trillions “cloud droplets”. ... Nonetheless, if you were to be able to touch a cloud, it wouldn’t really feel like anything, just a little wet.
Why do clouds not fall?
Clouds consist of tiny water droplets (or ice crystals) and, like all objects, they do fall, but at a very slow rate. Cloud droplets remain suspended in the atmosphere because they exist in an environment of gently rising air that overcomes the downward force of gravity .
Why do clouds turn GREY?
It is the thickness, or height of clouds , that makes them look gray. ... The tiny water droplets and ice crystals in clouds are just the right size to scatter all colors of light, compared with the smaller molecules of air that scatter blue light most effectively. When light contains all colors, we perceive it as white.
