It's kind of a zig zig. Look them up and you'll see.

Noctilucent clouds are found in the mesosphere, which is the third layer of Earth's atmosphere. They form at altitudes of around 50 miles (80 kilometers) above the Earth's surface and are visible only during astronomical twilight.

You may be referring to noctilucent clouds.

Noctilucent clouds are composed of ice crystals that form in the upper atmosphere, specifically in the mesosphere at altitudes of 50 to 85 km (31 to 53 miles). The ice crystals are composed of water and other compounds, like meteoric dust and chemicals released by volcanic eruptions. These materials combine to create the thin, wispy clouds that glow at night when illuminated by the Sun below the horizon.

Noctilucent clouds can be seen on clear midsummer evenings that form on the border between earth and space. So they are the highest.

No, the highest cloud is the noctilucent cloud, which forms in the mesosphere. Cirrus clouds are high altitude clouds, but not the highest.

Noctilucent clouds are the highest and are made of crystals of water ice. They are located in the Mesosphere some 76 kilometers high

Noctilucent clouds have been documented at heights of 76 to 85 kilometers (47-53 miles). http://science.nasa.gov/headlines/y2008/25aug_nlc.htm

cirrocumulus clouds range above 18,000 feet but cumulonimbus clouds range from near ground to above 50,000 feet.

Noctilucent clouds are the highest clouds in the Earth's atmosphere. They are located in the mesosphere at altitudes of around 76 to 85 kilometres (47 to 53 mi). They are normally too faint to be seen, and are visible only when illuminated by sunlight from below the horizon while the lower layers of the atmosphere are in the Earth's shadow.

Some words that have the root word "noc" include nocturnal (related to night), noctilucent (shining at night), and equinoctial (related to the equinox).

Miscellaneous clouds are types of clouds that don't belong to any specific cloud formation category. They include various cloud formations that don't fit neatly into the standard classifications, sometimes due to their unique appearance or formation process. Examples include the mammatus, noctilucent, and fallstreak hole clouds.

Examples of mesospheric phenomena include noctilucent clouds, meteor showers, and airglow. The mesosphere is the layer of Earth's atmosphere located between the stratosphere and thermosphere. It is known for its extreme cold temperatures and low air pressure.

The mesosphere is the layer of the Earth's atmosphere that lies between the stratosphere and the thermosphere. It is characterized by its extreme cold temperatures and the presence of noctilucent clouds, which are the highest clouds in the atmosphere. The mesosphere is also where most meteorites burn up upon entering the Earth's atmosphere.

The mesosphere does not directly affect life on Earth as it is too high up in the atmosphere. It plays a role in protecting the Earth's surface by absorbing and dissipating the energy from incoming meteors, preventing them from reaching the surface. Additionally, the mesosphere is important for certain atmospheric phenomena like noctilucent clouds.

One of the rarest types of clouds is the noctilucent cloud, which is a type of cloud that forms in the mesosphere at very high altitudes. They are typically seen in polar regions during the summer months and can appear to glow in the twilight sky.

The highest clouds in the sky, known as noctilucent clouds, are made of tiny ice crystals that form at very high altitudes in the Earth's atmosphere. These clouds typically occur at altitudes of around 50 miles (80 kilometers) above the Earth's surface in the mesosphere.

Yes. Noctilucent clouds are a rare type of thin cloud that form in the mesosphere in the higher latitudes. These clouds are so thin that they can only been seen when lit from below in the evening or at dawn.

The highest cloud type is called noctilucent clouds, which form in the mesosphere, about 50 miles above the Earth's surface. They are only visible during twilight and are made up of tiny ice crystals.

Most of the English words that come from the Latin word for "night" are from what's known as the "oblique stem" noct-: nocturne, nocturnal, noctilucent. One that preserves the nominative form nox is equinox ("equal night").

The stratosphere is a layer of Earth's atmosphere between the troposphere and mesosphere. Examples of phenomena found in the stratosphere include the ozone layer, which helps protect Earth from harmful ultraviolet radiation, as well as the presence of high-altitude clouds called noctilucent clouds. Commercial airplanes often fly in the lower stratosphere due to its stability and lack of turbulence.

In the mesosphere, you can find objects such as meteors, noctilucent clouds, and some types of stratospheric aerosols. The mesosphere is the layer of Earth's atmosphere between the stratosphere and thermosphere, and it's where many meteoroids burn up upon entering from space.

In the mesosphere, the most common occurrence is the formation of noctilucent clouds, which are thin and wispy clouds that form at high altitudes. Additionally, meteors burn up in the mesosphere, creating the phenomenon known as shooting stars. The mesosphere is also the coldest layer of Earth's atmosphere, with temperatures decreasing with altitude.

A glowing region in the atmosphere could refer to phenomena such as the auroras (Northern and Southern Lights) caused by the interaction of solar wind with the Earth's magnetic field. It may also refer to noctilucent clouds, high-altitude clouds that can appear to glow in the twilight sky due to their altitude and the way they scatter sunlight.

High-level clouds include cirrus, cirrostratus, and cirrocumulus. Middle-level clouds include altocumulus and altostratus. Low-level clouds include stratocumulus, stratus, and nimbostratus.

A low level cloud is a cloud that forms below 6,500 feet (2,000 meters) in the atmosphere. These clouds are typically composed of water droplets and are often associated with precipitation. Examples of low level clouds include stratus clouds, cumulus clouds, and stratocumulus clouds.

With the exception of rare stratospheric noctilucent clouds, cirrus forms the highest cloud layer (also cirrostratus or cirrocumulus). In the tropics (where the troposphere is thicker, that is tropopause is higher) cirrus can generally occur up to 50-60,000 feet (15-18000 metres), sometimes higher when associated with tropical cumulonimbus anvils.

Note that the possible height of cloud varies with location and airmass, so the highest cloud can occur in the tropics, the lower heights (with cirrus possible at 10,000 ft or 3500 m) in polar regions.

Studies have established that the majority of UFO observations are misidentified conventional objects or natural phenomena-most commonly aircraft, balloons, noctilucent clouds, nacreous clouds, or astronomical objects such as meteors or bright planets with a small percentage even being hoaxes.

These reports are simply other more prosaic phenomena that cannot be identified due to lack of complete information or due to the necessary subjectivity of the reports.

In ufology, the psychosocial hypothesis, abbreviated PSH, argues that at least some UFO reports are best explained by psychological or social means. It is often contrasted with the better-known extraterrestrial hypothesis (ETH).

The mesosphere is the third layer of the Earth's atmosphere located above the stratosphere and below the thermosphere. It is characterized by decreasing temperatures with altitude, reaching temperatures as low as -90 degrees Celsius. The mesosphere is also the region where most meteorites burn up upon entering the Earth's atmosphere due to the high concentration of gas molecules.

The highest clouds are polar mesospheric clouds, which, at heights from 76,000 to 85,000 m (altitude) are much higher than other types of clouds, such as cirrus and cumulonimbus. Cumulonimbus can exceptionally reach 23,000 m at the very top of a peaked formation, but these clouds normally form mainly within the 2,000 to 16,000 m range. Cirrus clouds, at a maximum height of about 18,000 m in tropical zones, are also much lower than polar mesosphericclouds.

Well, isn't that an interesting thought! The mesosphere plays an important role in our atmosphere, helping protect us from meteoroids and allowing for the beautiful phenomenon of noctilucent clouds. Without it, our atmosphere would be quite different, but nature has a way of finding balance, so I'm sure something else would step in to fill the gap. Just like in painting, every element has its place and purpose.

Clouds can form at various altitudes, so their distance from the sea surface can vary greatly. Typically, low-level clouds such as stratus clouds can be around 2,000 to 6,000 feet above the ground, while mid-level clouds like altocumulus can be about 6,500 to 20,000 feet high. High-level clouds like cirrus can be as high as 20,000 feet or more.

An approximate value can be calculated by the following expression: Condensation Level (in feet) = [Surface Temperature(F) - Surface Dew Point Temperature(F)]*(1000/2.2) or Condensation Level (in meters) = [Surface Temperature(C) - Surface Dew Point Temperature(C)]*(200) Solution: Dry Adiabatic Lapse Rate (DALR) => -5.5 F/1000 ft of altitude (-1C/100m) Saturated Adiabatic Lapse Rate (SALR) => -3.3F/1000ft of altitude (-0.5C/100m) The SALR is not linear and varies with the initial surface temperature The Level of Condensation will occur at the altitude where the Air Temperature is equal to the Dew Point temperature at that altitude. Setting the two equations equal to each other will give an approximate value. TA: temperature at altitude; TS: temperature at surface; DA: dew point temperature at altitude; DS: dew point temperature at surface TA = TS-(5.5F/1000ft)*altitude or TS-(1C/100m)*altitude DA = DS-(3.3F/1000ft)*altitude or DS-(0.5C/100m)*altitude Setting TA = DA and rearranging quantities gives the equations given above The level of condensation derived by the above method will only yield an approximate value.

The Mesosphere is the third layer in the Mantle.It is approximately 2550 km in depth. It is the biggest part of the Mantle. It extends from the bottom of the Asthenosphere to the core.

Clouds are divided into two general categories: layered and convective. These are named stratus clouds (or stratiform, the Latin stratus means "layer") and cumulus clouds (or cumuliform; cumulus means "piled up"), respectively. These two cloud types are divided into four more groups that distinguish the cloud's altitude. Clouds are classified by the cloud base height, not the cloud top. This system was proposed by Luke Howard in 1802 in a presentation to the Askesian Society. High clouds (Family A) * Cirrocumulus * Cirrus cloud * Cirrostratus Middle clouds (Family B) * Altostratus * Altocumulus Low clouds (Family C) These are found up to 2,000 m (6,500 feet) and include the stratus (dense and grey). When stratus clouds contact the ground, they are called fog. Clouds in Family C include: * Cumulus (Cu) * Cumulus humilis ** Cumulus mediocris * Stratocumulus (Sc) * Nimbostratus (Ns) * Stratus (St) Vertical clouds (Family D) These clouds can have strong up-currents, rise far above their bases and form at many heights. Clouds in Family D include: * Cumulonimbus (associated with heavy precipitation and thunderstorms) (Cb) * Cumulonimbus calvus ** Cumulonimbus incus ** Cumulonimbus with mammatus * Cumulus (Cu) * Cumulus congestus * Pyrocumulus Other clouds A few clouds can be found above the troposphere; these include noctilucent and polar stratospheric clouds (or nacreous clouds), which occur in the mesosphere and stratosphere respectively. Some clouds form as a consequence of interactions with specific geographical features. Perhaps the strangest geographically-specific cloud in the world is Morning Glory, a rolling cylindrical cloud which appears unpredictably over the Gulf of Carpentaria in Northern Australia. Associated with a powerful "ripple" in the atmosphere, the cloud may be "surfed" in glider aircraft.

Clouds form when rising air, through expansion, cools to the point where some of the water vapor molecules "clump together" faster than they are torn apart by their thermal energy. Some of that (invisible) water vapor condenses to form (visible) cloud droplets or ice crystals.

Scientists didn't knew ozone layer before 1880. It is because of lack of technology at that time.

The layers of Earth's atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has different characteristics, such as temperature changes, altitude ranges, and composition. The layers play a crucial role in regulating the climate, weather patterns, and protecting life on Earth from harmful radiation.
