What process causes clouds to form from water vapor at high altitudes?
H2o vapor is the name given to evaporating water. Water vapor in the air condenses every bit it is cooled. If the temperature of the deject dips below freezing, the modest water droplets freeze and create water ice crystals. As a event, clouds are made up of either microscopic h2o droplets or ice crystals. The type of cloud that forms depends on what is happening at its base.
If the surface is warm, such every bit a field of grass or a road, rut will be released when the liquid turns to gas every bit it evaporates. This is why hot days lead to clear skies - without these heat losses, clouds would form with their moisture content increased past the hotter temperatures.
The more humid the air is, the more likely it is to form clouds. Humidity is measured in percent, where 100% means fully saturated and 0% ways completely dry. Clouds consist of tiny particles called aerosols that tin can exist grit from soil or smoke from fires. When these particles get large enough, they may become visible to the naked eye as a thick layer over state or ocean. A common term for this kind of deject is fog. Aerosols also have an touch on on the weather past affecting how much radiation reaches the world'southward surface - thus influencing climate change - and they tin can as well have health effects for people who suffer from asthma or other respiratory diseases.
The college the humidity, the more likely it is for clouds to course because there is more water vapor in the air.
Is condensed water that falls from clouds, such as rain, snow, or hail, edible?
When the water vapor cools, it may condensate and produce clouds. This is referred to every bit condensation. On land, liquid water can fall as rain, snow, sleet, or hail. Equally these particles freeze they become rock table salt or glass, but only if there is enough wet in the air for this to happen. If not, then they evaporate again before they tin can freeze.
On other planets where there is no state, any h2o that condenses volition usually remain in a liquid state. Whether it tin exist fabricated into food depends on many factors such as the type of molecule information technology contains and how it was produced. Some molecules such as hydrogen peroxide cannot be broken down further and are therefore always toxic. Other molecules may be able to be split upwardly into smaller components that could be used by organisms for energy. These would be known as bio-molecules.
In conclusion, yeah, liquid h2o that has fallen from clouds is generally safe to eat. All the same, any organism that consumes it would also exist consuming its own version of poison ivy or sumac. Therefore, care should exist taken not to swallow whatsoever h2o that has fallen from the sky unless you know for sure that it is not poisonous.
How are h2o droplets converted into ice crystals?
Water vapor in a deject is transformed immediately into ice crystals. They come in an infinite multifariousness of forms and designs, all with six sides or branches. It was freezing pelting. When water aerosol come into contact with a cold surface, they freeze. The contact must be with a cool surface. If the temperature is in a higher place 0 degrees C (32 degrees F), and so no conversion volition occur.
Ice crystals tin can have many unlike shapes. Some common ones are needles, plates, bricks, and dice. Long, thin crystals are called hoar frost. Short, stubby ones are called block frost.
When clouds pass over a cold surface, such equally physical or metal, they may comprise some crystals that have grown in that location. These are chosen costless-draining crystals because they do not interlock with each other like pocket-size ice particles would. Instead, they stick out from the surface where they were formed. Freezing rain tin can likewise fall equally balls of ice instead of every bit drops. This is chosen hail. Hail tin can cause extensive damage to crops and human being-fabricated objects during storms, but it is also responsible for spreading out on roads in wintertime and covering them with a thin layer of ice.
Hail can exist either dense or loose. Dumbo hailstones are too heavy to be lifted past wind effects and then stay in identify until they melt or are blown away.
How does water vapor plow into ice?
Low temperatures cause water vapor in the atmosphere to either condense into a liquid or deposition to create ice crystals. Clouds are formed in the atmosphere by water droplets and water ice crystals, which are carried nearly the world past air currents. When sunlight strikes clouds, most of its energy is reflected back into space considering deject particles are white or grey. However, a small fraction of the lite falls on the globe's surface. This reduces the temperature of the cloud near the surface enough for some of the water vapor within it to condense into liquid aerosol that fall as rain or snow.
Water ice has 3 dissimilar crystal structures: hexagonal, rhombic, and cubic. The greatest density of ice (0.91 g/cm3) is found in cubic ice. The side by side highest density is seen in rhombic ice (0.85 yard/cm3), followed by hexagonal ice (0.81 g/cm3). Long bondage of side by side molecules with their axes all parallel result in a high density for rhombic and cubic ice.
Hexagonal ice has lower density than rhombic ice but higher density than cubic ice. This is because each molecule is tilted with respect to its neighbors, reducing the intermolecular force that would otherwise attract them together. Thus, the molecules are more than easily separated, allowing more space betwixt them.
What process causes clouds to form from h2o vapor at high altitudes?
Condenses When the invisible water vapor in the air condenses into visible water droplets or ice crystals, clouds form. To exercise this, the parcel of air must be saturated, i.e., it must be unable to keep all of the water information technology contains in vapor grade, causing it to condense into a liquid or solid state. Saturation occurs when there is enough wet in the atmosphere that any boosted will cause the mixture to become oversaturated and trigger more astringent atmospheric condition, such every bit rain or snow.
Clouds are very important considering they can touch how much rut reaches the earth's surface. Clouds also play a role in determining where rainfall occurs. The presence of clouds tin can fifty-fifty help control temperature by blocking out some sunlight during the day and dark.
The three main types of clouds are: stratiform, cellular, and atmospheric precipitation.
Stratiform clouds are flat layers of cloud that tin range from a few hundred feet to many miles across. They oftentimes class over big bodies of water like oceans or lakes and are usually white or low-cal gray in colour. Stratiform clouds act equally barriers between areas of warm and common cold air which allows for greater variation in temperature than would otherwise be the case. Because stratiform clouds don't move around much, they can be useful indicators of coming storm activity.
