Clouds

Clouds are classified into 4 main layers, with one layer which occurs extremely high up. They can be divided into the four 'families'. High clouds, which are Family A Middle clouds, which are Family B Low clouds, which are Family C Vertical clouds, which are Family D High clouds, which include ones such as Cirrocumulus and Cirrus clouds, occur at heights of around 30,000 feet. They generally have a very wispy appearance, generally due to the fact that a large portion of them are ice crystals. This is because the temperature at these altitudes can be well below freezing point. Middle clouds, such as the Altostratus cloud, are found at about 15,000 feet. The Altostratus cloud is generally grey or dark, like a rain cloud. However they are not so dark that you cannot see the sun through them! Low clouds include Cumulus, Stratocumulus and Cumulonimbus clouds. They are found around 6,500 feet, and are characterised by their much more defined 'cloud like' features. Cumulus clouds are the stereotypical cloud, quite heavy with a whispy edges. Cumulonimbus clouds however are storm clouds, and are very tall and dense. The heigh can reach well over 50,000 feet! The other cloud group appears in the mesosphere and the stratosphere, which is just below the mesosphere. They are typically made completely from ice due to the high altitudes.

"hot air rises at the poles becasue the sun is sending off direct sunlight to this area. the air moves outward to the poles. since the poles are reviecing indirect sunlight they are very cool so the air drops to the ground.

• droplets of water vapor suspended in the air near the ground
• an atmosphere in which visibility is reduced because of a cloud of some substance
• obscure: make less visible or unclear; "The stars are obscured by the clouds"; "the big elm tree obscures our view of the valley"
• daze: confusion characterized by lack of clarity
  
  
  Fog is a collection of liquid water droplets or ice crystals suspended in the air at or near the Earth's surface.While fog is a type of stratus cloud, the term "fog" is typically distinguished from the more generic term "cloud" in that fog is low-lying, and the moisture in the fog is often generated locally (such as from a nearby body of water, like a lake or the ocean, or from nearby moist ground or marshes). Fog is distinguished from mist only by its density, as expressed in the resulting decrease in visibility: Fog reduces visibility to less than 1 km (5/8 statute mile), whereas mist reduces visibility to no less than 1 km .For aviation purposes in the UK, a visibility of less than 5 km but greater than 999 m is considered to be mist if the relative humidity is 70% or greater - below 70% haze is reported.
  The foggiest place in the world is the Grand Banks off the island ofNewfoundland, the meeting place of the cold Labrador Current from the north and the much warmerGulf Stream from the south. Some of the foggiest land areas in the world include Argentia, Newfoundland and Point Reyes, California, each with over 200 foggy days per year. Even in generally warmer southern Europe, thick fog and localized fog is often found in lowlands and valleys, such as the lower part of the Po Valleyand the Arno and Tiber valleys in Italy or Ebro Valley in northeastern Spain, as well as on the Swiss plateau, especially in the Seeland area, in late autumn and winter. Other notably foggy areas include coastal Chile (in the south), coastal Namibia, and theSevernaya Zemlya islands.

High or low pressure lies along the subtropical jet stream, depending on the time of year. The pressure gradient follows the path of the jet stream.

Increasing air pressure generally means more clear skies and little precipitation.

Water is a solid at temperatures below 0 degrees Celsius (32 degrees Fahrenheit).

Water's freezing point is 0 degrees Celsius, so anything below that is a solid. Water's boiling point is 100 degrees Celsius, so anything between 0 and 100 would be a liquid, and anything above 100 would be a gas.

The formation of water droplets on a cold glass are a physical change because it's nothing more than condensation. The water that is in the air is a gas, and it has undergone a change of state to become a liquid (the droplets). If the water and the glass fused and made another element that could not be made back into either of its two original forms, then it would be a chemical change.

it becomes a mist either way or it evaporates really fast then turns back into the two gases : hygergon and,oxygen. hope that helps!! == Precipitation. Mist and fog are just low lying clouds, so yeah that could happen.

Here in north carolina, the weather is like that over half of the year, as humidity (moist air) is so bad that you can practically drink the air, especially in the summer, when humidity is at an unbearable 98%!

It can form a runoff, soak into the ground and become ground water, either way, it flows into the ocean or another body of water, evaporate again, condensate, then rain to start the process over again.

Layered or stratified clouds are stratus clouds. These types of clouds are low-lying gray clouds that sit under 6,000 feet.

The enthalpy changes accompanying a change of state (e.g., melting, boiling) involve breaking or forming intermolecular forces, which may require more energy than simply raising the temperature of a substance at that state. This is because changes of state involve a phase transition, which requires additional energy to overcome the intermolecular forces holding the substance together.

Cool it. The moisture in the air condenses to form a cloud when it is cooled. Eventually the moisture droplets are big enough to start to precipitate to form rain.

You see your cloud of breath when you walk outside on a cold day and the moisture in your breath condenses to form a visible cloud.

because of the clouds have feelings too don't they now.

Water must gain or lose energy (through heat or pressure) in order to change state. When an object is "heated" what is actually happening is the molecules in the sample are speeding up. When it is "cooled" the molecules are slowing down. The same thing happens when the pressure is changed: when you compress something energy is added, and when you expand energy is released. So for water to change state, you need to change the amount of energy in the sample by changing the amount of heat or pressure.

Both molecules are made up of 2 hydrogen and 1 oxygen, referring to its atoms.

Humidity is not directly affected by altitude. However, humidity is affected by air density and temperature. At high altitudes, the air is usually much thinner (lower pressure) and often the temperature is lower. At low temperatures and low pressures, air cannot hold as much water. Thus the humidity is necessarily low when the air is thin and cold. At high temperatures and high pressures, air can hold much more water. However, air that is hot and thick doesn't necessarily have a high humidity; but it does have the potential to hold more water.

Under normal temperature and atmospheric pressure conditions propane is gaseous.

However, when the temperature is reduced to below −42.09 °C or when it is stored under high pressure (approx 177 psi), it takes the form of a liquid.

It is highs 37 and low 28



hope it helped:)

Condensation.

The transformation of water vapours in liquid water is called condensation, a change of phase.

For something to evaporate, it must get warmer by absorbing some energy. Since energy cannot be created from nothing, it must come from somewhere; the environment surrounding the material. So as the material gets warmer and evaporates, the surrounding area gets colder. For example, sweat: as the liquid evaporates from the skin it absorbs energy from the body to do so, effectively cooling it down.

Physical, because the gas is still the same gas, just under pressure

Some gasses may undergo spontaneous chemical reactions under very high heat and/or pressure. For example ozone under high pressure will fairly rapidly decay into oxygen gas.

The water vapor in the air goes from a gas state to a liquid state onto the grass.

Uranus is a pale blue color due to the presence of methane gas in its atmosphere. This methane absorbs red light from the sun, reflecting the blue-green hues that we see from Earth.

A wind is a moving air mass. If the air mass has passed over a large ocean, it could mean clouds and rain falling over an area.
