Clouds
A cloud is a visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes up to several miles above sea level. They are generally produced by the condensation of water vapor. Other clouds, less commonly seen, are composed of smokes or dusts.

Where did the clouds come from?
How are clouds formed?
All air contains water, but near the ground it is usually in the form of an invisible gas called water vapor. When warm air rises, it expands and cools. Cool air can't hold as much water vapor as warm air, so some of the vapor condenses onto tiny pieces of dust that are floating in the air and forms a tiny droplet around each dust particle. When billions of these droplets come together they become a visible cloud.

Are there stars in the thermosphere?
No, stars are located in outer space beyond Earth's atmosphere. The thermosphere is a layer of Earth's atmosphere that begins about 80 kilometers above the surface and extends to about 550 kilometers where it transitions into the exosphere. The thermosphere is not a place where stars are found.
Water vapor rises because it is?
Vaporized water rises because it is 100 degrees Celsius or warmer and is therefore warmer than the surrounding air and warmer air always rises above colder air.
About how many years ago do scientists suggest that earth cooled enough for water vapor to condense?
THEY THINK about 3.9 billion years ago (:
4.4 billion years ago(:
What are the elements of a cloud?
The elements in a cloud are
- Water molecules
- Condensation Nuclei
and if you are looking for the three things needed to make a cloud the third is rising and cooling.
Cumulus clouds are puffy. They have flat bottoms and are low in the sky. Cumulus clouds usually mean fair weather. Cumulus clouds are a type of cloud with noticeable vertical development and clearly defined edges.
Cumulus clouds are often precursors of other types of clouds, such as cumulonimbus, when influenced by weather factors such as instability, moisture, and temperature gradient. Cumulonimbus clouds may be associated with phenomena such as landspouts, waterspouts and tornadoes.
Do Cloud and Aerith have a child?
Unfortunately it's a no and wait...another no...cause the Romance between Cloud and Aerith isn't well developed to the point they would have a one night stand (and also chances are gone now thanks to Sephiroth) the only given chances for Cloud having a kid or two of his own is if he and Tifa actually get together.
eventually they will, I mean the two have been living together for over 3 years now, they have been through a lot, it's going to happen eventually I mean chances are they may need an heir to take down Sephiroth if ever he finds a way to revive himself a few years after Cloud has passed his oversize swords to an heir when Cloud well can't lift the damn things anymore I mean it will look like how Wolverine and Saber-tooth will forever be duking it out on each other or even the mighty Batman and Joker gonna be chasing each other in the streets of Gotham.
but don't get your hopes up about Cloud and Tifa or Cloud getting himself either a Son or Daughter cause developing such new characters to the mix would result in turning them to be Mary sues/Gary stu or eventually screw the whole story of Final Fantasy VII over
What are water droplets that are too heavy to float make?
Water droplets that are too heavy to float will fall to the ground as precipitation, such as rain or snow.
Why does air near the surface have to be moist in order for a thunderstorm to form?
Moist air helps thunderstorms develop because it provides the necessary water vapor for condensation and cloud formation. This condensation releases latent heat, fueling the thunderstorm's updrafts and creating the unstable atmospheric conditions needed for thunderstorm growth. Higher moisture levels also contribute to the development of precipitation within the storm.
What happens if nimbo appeaers at the beginning of a cloud name or nimbus appears at the end?
If the term "nimbo" appears at the beginning of a cloud name, it indicates that the cloud is capable of producing precipitation. If "nimbus" appears at the end of a cloud name, it also signifies that the cloud can produce precipitation as it is already saturated with moisture.
What does heat radiated from Earth's surface do?
Heat radiated from Earth's surface gets absorbed by greenhouse gases in the atmosphere, such as carbon dioxide and water vapor. These gases trap the heat and re-radiate it back towards the surface, creating a warming effect known as the greenhouse effect. This natural process helps regulate Earth's temperature and maintain conditions suitable for life.
What causes the weather to be sunny?
Sunny weather occurs when there are few or no clouds in the sky, allowing sunlight to reach the ground unimpeded. This typically happens when high pressure systems are in control, leading to stable atmospheric conditions and clear skies.
Occurs when water vapor cools and changes back into liquid droplets?
This process is called condensation. It happens when the temperature of water vapor decreases, causing the vapor to lose energy and transition into liquid form. Condensation is commonly observed when warm air cools down, such as when moisture in the air collects on a cold surface.
What effect might jet streams have on airplane travel?
The atmosphere is filled with constantly moving air streams, determined by the temperature differences in various areas of the earth. One of these is the jet stream, which runs east to west around the world.

How water vapour as a greenhouse gas contributes to the greenhouse effect?
Water vapor acts as a greenhouse gas by trapping heat in the Earth's atmosphere. When sunlight warms the Earth's surface, water evaporates and enters the atmosphere where it can absorb and re-radiate heat. This process helps regulate the Earth's temperature, similar to how a greenhouse traps heat inside.
What is the term used to describe clouds with precipitation?
Clouds with precipitation are often referred to as nimbostratus clouds. These clouds are characterized by their uniform, thick, gray layers that produce steady rain or snow.
Which is thicker air and water vapour?
The density of dry air is higher than the density of water vapor.
Using the ideal gas equation,
p=(rho)(R*/M)T
rho = pM/(R*T)
M is the molecular weight of the substance.
The average molecular weight of air is 28.8 g/mole, while for water vapor it's 18 g/mole, so dry air is more dense than water vapor by a factor of 28.8/18.
What State has the most cloudy days a year?
Alaska has the most cloudy days per year, with an average of 320 cloudy days. This is due to the state's high latitude and proximity to the Pacific Ocean, which contribute to its consistently overcast weather.
How do land and sea breezes work?
Onshore breeze can be due to sunshine warming of the land mass, this causes the air over the land to rise and suck air over adjacent water in towards land.
Sea breeze is the converse with cooling landmass (after the Sun has set) pulling air from higher regions down towards the land and pushing air out over water (which has a relatively more stable temperature).
What do stratus clouds produce?
They look like a huge gray blanket that hangs low in the sky. Sometimes stratus clouds are on the ground or very near the ground, and then we call them fog.
Which of the following is true about clouds at medium altitudes?
They are composed mostly of liquid water
They are composed mostly of liquid water

Causes columns of clouds to spin and may form a funnel cloud?
The rotation in a thunderstorm that produces a tornado comes from wind shear, a difference in wind speed and direction with altitude. In the systems that produce tornadoes in the northern hemisphere, you will typically find lower level winds coming out of the west with winds higher up coming out of the south. A counterclockwise change in direction. This creates a counterclockwise circulation in the thunderstorm that can produce a tornado. In the Southern Hemisphere the upper level winds are out of the north and clockwise rotation results.
