Clouds are technically part of both the atmosphere and the hydrosphere.
Why are clouds considered 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.
Clouds occur in the lower two atmospheric layers that comprise the troposphere extending from the surface to about 12 km altitude. The uppermost atmospheric layer extends from about 12-100 km and is comprised, going upward, of the stratosphere (containing the ozone layer), the mesosphere and the thermosphere.
Why are clouds in the hydrosphere?
Water moves through the hydrosphere in a cycle. Water collects in clouds, then falls to Earth in the form of rain or snow. This water collects in rivers, lakes and oceans. Then it evaporates into the atmosphere to start the cycle all over again.
The hydrosphere includes water storage areas such as oceans, seas, lakes, ponds, rivers, and streams.
What particles are in clouds?
Clouds usually form around tiny airborne particles called aerosols. Clouds are made of water droplets, ice crystals, or a mix of both. When the sun warms the surface of the Earth, water from oceans and lakes, soil, and plants changes from a liquid to a vapor.
Are clouds just water?
While it’s true that clouds contain water, they actually aren’t made of water vapor. If they were, you wouldn’t be able to see them. The water that makes up clouds is in liquid or ice form. The air around us is partially made up of invisible water vapor.
What are clouds 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.
In which sphere are clouds?
Clouds generally form within the troposphere, or the layer of atmosphere closest to the earth.
What is part 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.
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.
What are the 4 parts of the hydrosphere?
The hydrosphere is the sum of Earth’s water, in the ocean, the ground, on the surface, and in the air.
Are clouds a gas?
The majority of the cloud is just plain air in which the invisible water vapor is mixed with and the very tiny water drops and ice particles are suspended in. A cloud is a mixture of gas, liquid and solids.
What is the formation of clouds called?
Water can also be transformed directly from solid to gas (sublimation), or the reverse, through a process called deposition. We will see these various processes in the formation of clouds. Clouds are formed when air contains as much water vapor (gas) as it can hold.
How do clouds store water?
Because they are so small they are easily kept up by the rising air. So the reason that clouds can hold water droplets is because the air in clouds is rising, and the rising air keeps pushing the water droplets up. Basically, it’s the same with snow, but a cloud holding snow or ice crystals must be colder.
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.
Why do clouds not fall?
Like everything on this planet, the tiny droplets that make up a cloud are drawn towards the Earth by gravity. But these droplets are so small that it’s hard for them to push past all the air beneath them. This means that they don’t fall very fast at all ” in fact, only about one centimetre per second.
Can the sky fall?
They literally fall out of the sky, in all shapes and sizes, from specks of comet dust to full-blown asteroids, traveling up to a hundred thousand mph. And when they hit, they do not disintegrate harmlessly in the atmosphere as most would on Earth.
What is cloud in geography?
Clouds are visible accumulations of tiny water droplets or ice crystals in the Earth’s atmosphere. Clouds differ greatly in size, shape, and color. They can appear thin and wispy, or bulky and lumpy.
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.
How are clouds formed 7?
Water present on the earth’s surface gets evaporated due to sunlight, and then rises up in the atmosphere. On reaching a certain height, water vapour present in air condenses to form tiny droplets of water. These water droplets collect to form clouds that float in air.
How are clouds part of the water cycle?
Condensation is crucial to the water cycle because it is responsible for the formation of clouds. These clouds may produce precipitation, which is the primary route for water to return to the Earth’s surface within the water cycle. Condensation is the opposite of evaporation.
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.
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.
What are the 4 parts of the atmosphere?
The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere.
Which of the following layers of the atmosphere is free from clouds?
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 are the 7 layers of the atmosphere?
What is atmosphere in geography?
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.
Does the Moon have an atmosphere?
Just as the discovery of water on the moon transformed our textbook knowledge of Earth’s nearest celestial neighbor, recent studies confirm that our moon does indeed have an atmosphere consisting of some unusual gases, including sodium and potassium, which are not found in the atmospheres of Earth, Mars or Venus.
Are mood and atmosphere the same?
Both atmosphere and mood refer to feelings, but there’s a small difference. The atmosphere is an external feeling coming from the physical environment. The mood is the internal feeling of the reader. The external feeling induces the excitement in the reader.
What are 5 things in the hydrosphere?
The hydrosphere includes water in oceans, lakes, streams, ponds, groundwater, glaciers and other ice forms. 5.
What part of the Earth sphere make up hydrosphere?
All of the liquid water on Earth, both fresh and salt, makes up the hydrosphere, but it is also part of other spheres. For instance, water vapor in the atmosphere is also considered to be part of the hydrosphere. Ice, being frozen water, is part of the hydrosphere, but it is given its own name, the cryosphere.
Can I 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.
Can you stand on clouds?
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.
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.
Why do the clouds look like ripples?
Gravity waves in the atmosphere are visible through clouds, which showcase a ripple-like pattern in the sky. The clouds from gravity waves form at the upper crest of the wave, revealing this otherwise invisible phenomenon.
How do clouds float?
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.
Why all clouds do not bring rain?
Clouds produce rain when tiny droplets of liquid water begin to stick together, forming larger and larger drops.it won’t produce any rain. For example, if there aren’t enough droplets of water in a cloud to collide and form large drops, the tiny droplets will stay suspended in the air and it won’t rain.
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. That’s the equivalent of 100 elephants.
What keeps clouds in sky?
The sun heats the earth, and causes water on the ground to evaporate3. The water rises, cools, and condenses. A cloud is formed! Clouds form when warm wet air rises and condenses in cold air.
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).
Are Frozen clouds Possible?
Yes, there are high-altitude clouds made of ice crystals, for example cirrus clouds. You do not need to fulfill any condition of having a lower density than surrounding air, much like regular clouds (composed of water droplets) do not require the density of water to be lower than that of air.
Can a cloud touch the ground?
Some clouds are high up in the sky. Low clouds form closer to Earth’s surface. In fact, low clouds can even touch the ground. These clouds are called fog.
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.
What is the heaviest cloud?
Cumulonimbus (from Latin cumulus, “heaped” and nimbus, “rainstorm”) is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents. If observed during a storm, these clouds may be referred to as thunderheads.
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.
