If water vapor is invisible

Water vapor isn't invisible. Whether you can see it just depends on how densely it is concentrated. You don't see the low concentration in the air around you, but you can see clouds. You can also see the steam (water vapor) when you boil water.

Different types of clouds are formed by differing temperatures, altitudes, and weather conditions.

High-Level Clouds

High-level clouds form above 20,000 feet (6,000 meters) and since the temperatures are so cold at such high elevations, these clouds are primarily composed of ice crystals.

Mid-Level Clouds

The bases of mid-level clouds typically appear between 6,500 to 20,000 feet (2,000 to 6,000 meters). Because of their lower altitudes, they are composed primarily of water droplets, however, they can also be composed of ice crystals when temperatures are cold enough.

Low-level Clouds

Low clouds are of mostly composed of water droplets since their bases generally lie below 6,500 feet (2,000 meters). However, when temperatures are cold enough, these clouds may also contain ice particles and snow.

Vertically Developed Clouds

Probably the most familiar of the classified clouds is the cumulus cloud. Generated most commonly through either thermal convection or frontal lifting, these clouds can grow to heights in excess of 39,000 feet (12,000 meters), releasing incredible amounts of energy through the condensation of water vapor within the cloud itself.

High-Level Clouds

Cloud types include: cirrus and cirrostratus.

Cirrus Clouds

thin and wispy

The most common form of high-level clouds are thin and often wispy cirrus clouds. Typically found at heights greater than 20,000 feet (6,000 meters), cirrus clouds are composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus generally occur in fair weather and point in the direction of air movement at their elevation.

Cirrostratus Clouds

sheet-like and nearly transparent

Cirrostratus are sheet-like, high-level clouds composed of ice crystals. Though cirrostratus can cover the entire sky and be up to several thousand feet thick, they are relatively transparent, as the sun or the moon can easily be seen through them. These high-level clouds typically form when a broad layer of air is lifted by large-scale convergence. Sometimes the only indication of their presence is given by an observed halo around the sun or moon. Halos result from the refraction of light by the cloud's ice crystals. Cirrostratus clouds, however, tend to thicken as a warm front approaches, signifying an increased production of ice crystals. As a result, the halo gradually disappears and the sun (or moon) becomes less visible.

Mid-Level Clouds

Cloud types include: altocumulus, altostratus.

Altocumulus Clouds

parallel bands or rounded masses

Altocumulus may appear as parallel bands (top photograph) or rounded masses (bottom photograph). Typically a portion of an altocumulus cloud is shaded, a characteristic which makes them distinguishable from the high-level cirrocumulus. Altocumulus clouds usually form by convection in an unstable layer aloft, which may result from the gradual lifting of air in advance of a cold front. The presence of altocumulus clouds on a warm and humid summer morning is commonly followed by thunderstorms later in the day.

Low-Level Clouds

Cloud types include: nimbostratus and stratocumulus.

Nimbostratus Clouds

dark, low-level clouds with precipitation

Nimbostratus are dark, low-level clouds accompanied by light to moderately falling precipitation. Low clouds are primarily composed of water droplets since their bases generally lie below 6,500 feet (2,000 meters). However, when temperatures are cold enough, these clouds may also contain ice particles and snow.

Stratocumulus Clouds

low, lumpy layer of clouds

Stratocumulus clouds generally appear as a low, lumpy layer of clouds that is sometimes accompanied by weak intensity precipitation. Stratocumulus vary in color from dark gray to light gray and may appear as rounded masses, rolls, etc., with breaks of clear sky in between.

Clouds with Vertical Development

Cloud types include: fair weather cumulus and cumulonimbus.

Fair Weather Cumulus Clouds

puffy cotton balls floating in the sky

Fair weather cumulus have the appearance of floating cotton and have a lifetime of 5-40 minutes. Known for their flat bases and distinct outlines, fair weather cumulus exhibit only slight vertical growth, with the cloud tops designating the limit of the rising air. Given suitable conditions, however, harmless fair weather cumulus can later develop into towering cumulonimbus clouds associated with powerful thunderstorms.

Fair weather cumulus are fueled by buoyant bubbles of air, or thermals, that rise upward from the earth's surface. As they rise, the water vapor within cools and condenses forming cloud droplets. Young fair weather cumulus have sharply defined edges and bases while the edges of older clouds appear more ragged, an artifact of cloud erosion. Evaporation along the cloud edges cools the surrounding air, making it heavier and producing sinking motion (or subsidence) outside the cloud.

Cumulonimbus Clouds

reaching high into the atmosphere

Cumulonimbus clouds (Cb) are much larger and more vertically developed than fair weather cumulus. They can exist as individual towers or form a line of towers called a squall line. Fueled by vigorous convective updrafts (sometimes in excess 50 knots), the tops of cumulonimbus clouds can easily reach 39,000 feet (12,000 meters) or higher.

Lower levels of cumulonimbus clouds consist mostly of water droplets while at higher elevations, where temperatures are well below 0 degrees Celsius, ice crystals dominate. Under favorable atmospheric conditions, harmless fair weather cumulus clouds can quickly develop into large cumulonimbus clouds associated with powerful thunderstorms known as supercells.

Vater vapour isnt invisible. Its just too small and not concentrated enough to see. VERY SMALL PARTICLES

Thats why clouds are visible. This is where all the vapour is collecting and condensing in large amounts.

The different clouds are still basically the same thing.

Low level small clouds are normally small convective clouds from the water vapour near by.

Thunderstorms are bigger versions of these with ice at the top due to how high they are.

those reallllly high wispy ones are pretty much teh same, but made completely out of ICE. just frozen water vapour.

Water vapor is invisible

What you are seeing when there's fog, or clouds, or wisps coming off a pot of boiling water is tiny little liquid droplets that condensed out of vapor and are suspended in the air. Or in the case of some clouds it's tiny solid crystals of ice, not tiny droplets of liquid water.

Water vapor is not invisible, when you boil water you can see the vapor, its like a white gas. The reason you cant see vapor in the air, its because its mixed with other gases. Clouds are mostly concentrated mass of water vapor, thats the reason it looks white.

When the sun rays heat absorbs the Earth's bodies of water then they become evaporated. As all the water that had been absorbed it becomes condensed into clouds.

clouds are actually made with water vapor and other particles in the air...

Good question ...Well its true water vapour is invisible..Clouds are formed when water vapour condenses on dust particles..thus forming clouds which are visible

If the air is hot it will be invisible , but as it cools down it will become visible. If it cools more it will rain..

true
