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.

An Okta is a unit of measure to measure cloud cover.
Cloud cover is how much cloud there is in the sky.
A bit like a centimetre, the bigger the number of Oktas the more cloud there is, the more centimetres, the longer the object being measured.
Is the amount of water in the air called condensation true or false?
False. this is called humidity. Condensation is when water vapor condenses into liquid water.
What is it called when ice and snow turn directly into water vapor?
The process of ice and snow turning directly into water vapor is called sublimation. Sublimation occurs when a substance transitions from a solid state to a gaseous state without first passing through the liquid state.
What process of going from a gas to a liquid?
When something changes state from a liquid to a gas, evaporation or boiling has taken place. The difference might be that in evaporation, atoms or molecules of the substance "break free" of the liquid and become a gas. In boiling, there is enough heat present that the change is rapid.
What is a fixed volume and fixed shape?
Fixed volume has a fixed shape irrespective of quantity of its contents.usually solid containers,vessels,plastic buckets have fixed volume and shapes but may contain different amounts of matter.
Clouds are made up of tiny water droplets or ice crystals that have condensed together in the atmosphere. They form when warm air rises and cools, causing the water vapor to condense into visible droplets. Clouds play a crucial role in Earth's climate system by reflecting sunlight and trapping heat.
What is tiny crystals that form when water vapor condenses near the ground and freezes?
Frost is the term used to describe tiny ice crystals that form when water vapor in the air condenses and freezes on surfaces near the ground.
What type of cloud might precede a heavy snow?
Cirrostratus clouds are typically seen before a heavy snowfall. These high-altitude clouds can cover the sky in a thin layer and often indicate that precipitation is on the way.
What kind of clouds are found along cold front?
Along a cold front, you can typically find cumulonimbus clouds, which are associated with precipitation such as thunderstorms and heavy rainfall. These clouds form as warm air is forced to rise rapidly along the front, leading to the development of intense convective activity.
Are stratus clouds or cirrus clouds found closer to the gound?
Stratus clouds are found closer to the ground compared to cirrus clouds. Stratus clouds usually form at low altitudes, while cirrus clouds are higher up in the atmosphere.
Is rising air associated with a low pressure cell?
First answer was incorrect (in this thread)....
Here's the breakdown:
Regions of sinking air are called highs, high pressure regions or anticyclones. Clear skies and fair weather usually occur in these regions.
Regions of rising air are called lows, low pressure regions, depressions or cyclones. Clouds rain and strong winds often occur in these regions.
What is the process called when clouds turn into rain?
The process where clouds release precipitation in the form of rain is called precipitation or rain formation. It occurs when water droplets in a cloud combine to form larger droplets that eventually become heavy enough to fall to the ground as rain.
How does air in a high pressure system generally circulate?
In a high-pressure system, air generally circulates in a clockwise direction in the Northern Hemisphere and counterclockwise in the Southern Hemisphere due to the Coriolis effect. This results in air descending and diverging at the surface, creating clear skies and stable weather conditions. High-pressure systems are associated with sinking air and little to no precipitation.
What is the relationship between dew point temperature and air pressure?
Dew point is the temperature at which the air reaches saturation. Warmer air can retain more moisture than cooler air. So, ignoring other factors such as pressure, when the temperature drops to the dew point temperature, the air becomes saturated and therefore, if there is actually moisture in the air (is there a cloud?), it will start to rain or snow.
Do low cumulonimbus clouds bring both tornadoes and thunderstorms?
Thunderstorms form from cumulonimbus clouds, but they don't have to be low. Some of these thunderstorms can produce tornadoes, but not all. A thunderstorm is the only thing that can produce a tornado. Tornadoes form best from low-based thunderstorms.
Do nimbus clouds produce tornado?
Nimbus clouds can be associated with severe weather, including tornadoes, but they do not directly cause tornadoes. Tornadoes form when conditions such as instability, wind shear, and a triggering mechanism come together in the right way. Nimbus clouds can be a sign of these conditions, but they are not the sole cause of tornadoes.
What are the large white clouds that look like balls of cotton - or cotton wool - called?
cumulus clouds get puffs in themm becuse how many times they whent in to the warter cycil in just like when girls get on there pierod they have a cycle in get blouted so thats why the clouds get really bif in fat just like when girl get blouted in big for a little while in follow me on vine
What type of weather stationary front bring in?
A stationary front can bring prolonged periods of unsettled weather, with a mix of precipitation such as rain, snow, or thunderstorms. The weather can be variable along a stationary front, often with cloudy skies and light winds. Temperature changes along a stationary front can also lead to differing weather conditions on either side.
What tells the amount of water vapor in the air?
The amount of water vapor in the air is typically measured using a parameter called relative humidity. This value indicates the percentage of water vapor present in the air relative to the maximum amount of water vapor the air can hold at a given temperature. Another common measurement is the dew point, which is the temperature at which air becomes saturated and water vapor begins to condense.
What will happen if humidity increases until the air cannot hold more water vapor?
If humidity increases until the air cannot hold more water vapor, the excess water vapor will be released as precipitation, leading to rain, snow, or other forms of precipitation. This process helps balance the amount of water vapor in the air.
How did condensation of water vapour form oceans?
- The volcanoes on early Earth pumped more and more water vapour into the atmosphere. This caused the atmosphere to change.
- As the water vapour increased and the temperature of the Earth and its atmosphere continued to fall. This caused water droplets to form in the atmosphere through a process called condensation.
- As the water droplets increased in size, they eventually fell to the surface of the Earth and accumulated. This was the beginning of the first oceans.
- The carbon dioxide gas reacted with the accumulated water (dissolution) and the amount of carbon dioxide in the atmosphere decreased. Eventually, living organisms appeared in the oceans. The organisms that evolved used the carbon dioxide available in the oceans in different ways. Some of the marine organisms incorporated the carbon dioxide into their shells. When those organisms died their shells accumulated on the floor of the oceans and became carbonate rocks.
- Other marine organisms began to use carbon dioxide in chemical reactions to produce sugars that they could store for energy and release oxygen into the atmosphere. This process is called photosynthesis. These organisms were the first primitive plants.

Which holds more water vapor 12kg of air or 20kg of air?
At the Chemical Convention known as STP, or Standard Temperature and Pressure, 20 kg of Air contains more water vapor.
What conditions are responsible for a severe rainstorm?
Severe rainstorms can occur due to factors such as warm, humid air rising rapidly, colliding air masses with differing temperatures, and the presence of a weather system like a low-pressure area or front. These conditions can lead to the formation of strong thunderstorms with heavy rainfall.
Do clouds form when water condensation?
Yes, clouds form when water vapor in the air condenses into liquid water droplets or ice crystals. This process occurs when the air becomes saturated with water vapor and the droplets or crystals accumulate to form visible clouds in the atmosphere.
What three characteristics must an air mass have to be considered an air mass?
The three characteristics of air mass :
1. It must be a matter( molecules ) in gaseous state.
2. It must occupy space over the terrestrial zone called atmosphere.
3. It must have the right mixture of Oxygen,nitrogen & other gases to constitute
air
