How would you classify CLOUDS - Solid? Liquid? or Gas?

Water vapor is transparent (for most purposes) and so mere humidity in the atmosphere can't be a cloud. Since clouds don't have motors keeping them in the air, and yet stay there for hours in some cases, they can't be solid, for if they were, they'd fall out of the sky and we'd find cloud bits laying around on the ground. And the same is true for liquid as well. \n\nSo what's a cloud? Mostly, it's very small bits, so small that air currents can keep them in the air. The bits can be solid (eg, ice crystals of which snowflakes are examples), or liquid (eg, little drops of water, of which rain is an example). In either case, enough of these small things begin to look white as light passes thorough them and is reflected and refracted and generally diverted. Kind of like the effect of fine particulate suspensions in water. They are sometimes referred to as milky looking. Indeed, milk is white for a similar reason.\n\nThese are usually formed around dust bits, for real. High humidity (forced by cooling temperatures) produces supercooling (ie, ready to condense, if a trigger can be found). The dust motes provides the trigger. With updraft winds, a condensed drop can grow pretty large. And if it goes high enough, and gets cold enough, the drop can freeze (and thus make hail). If the orignal condensation is sufficiently cold, then water will be added to an ice crystal. With the proper history, such crystals become snowflakes.

Clouds are made of water vapor.  You inhale clouds every time you walk into a patch of fog, because fog is just a cloud at ground level.  Clouds are formed when water evaporates from the surface of the Earth and makes its way upward.  The water condenses and we get a cloud.  When clouds get too laden with water, it falls in liquid form and we get rain.

B Steam. Steam is the gases form of water. all of the rest are liquid forms of water. Note: what a lot of people think of as steam is not steam. Steam is an invisible gas, once it cools it becomes fog, clouds, and eventually mist. \n\nI had to add this because one of the previous persons was correct in noting that Clouds are sometimes made of ice crystals, so steam is still the most correct answer, but real clouds that are frozen is also correct.

Clouds are characterized by their height.  Low, medium, high, and extensive vertical development.  Then they are given prefixes and suffixes such as "nimbus" for rain clouds, and "alto" for low clouds, just to name a couple.  There are two main types of clouds: Cumulus (which are the puffy white ones)are associated with an unstable atmosphere, good visibility, and intermitten precipitation. Stratus (which are long and skinny) on the other hand are associated with a stable atmosphere, poor visibility, and steady precipitation.

the three properties of earth science are gas, liquid, and, solid. wind (or air moving quickly) is a gas.

They are shaped by the wind and heat.\nSee in\nhttp://allaboutweather.tripod.com/cloudclassification.htm

You can see clouds because clouds aren't gases.  They're condensed water droplets and ice crystals that aren't big enough to fall to the ground.  If clouds were actually made of water vapor, you couldn't see them.  Steam isn't completely gaseous, which is why you can still see it.  Smoke is visible because it's not a gas either, it's a colloid; it's a solution of solid particles in air.

A cloud is a visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes ranging up to several miles above sea level.

Solid. Most elements at standard atmospheric temperature and pressure are solids. Some of the non-metals are gases, but only Mercury and Bromine are liquids at STP.\n\nEDIT: Gloo-gal, why answer if you don't know or don't care?

I remember this question since it was on the test once:\n\nList the following kinds of matter by how well they conduct heat (from the best to the worst): Wood; air; metal; water.\n\nMy answer was the correct one and it was: Metal; water; wood; air.

A solid, unlike a liquid or a gas, does not take the shape of its container.\nPour some water into a glass and the water takes on the shape of the glass, pour this water onto the floor and now the water has an entirely different shape.  The same goes for gasses.  However, put some solid object in a glass, on the floor, ..., and it still has the same shape.\n\nBoth solids and liquids have definite volumes, unlike gasses.  Solids and liquids are considered "incompressible".  No matter how much you squeeze them, they retain their volume.  Gasses however can be compressed/expanded depending on the force acting on them.

Very simple. Its the transformation straight from solid to gas, skipping the liquid stage. Most common example it dry ice placed in water. The fog you see is mostly carbon dioxide gas.

Air is composed of eight or so chemical molecues and combines to create a gas. Water is composed of hyrogen and oxygen molecues and exists as a liquid or solid state (ice).  The difference in density of comparing a gas to a liquid is that the gas is less dense than the liquid, therefore offering less resistance to your hand.

I would say winter, you said summer might be, but those clouds usually are from thunderstoms, which die out rather quickly, but winter makes snow storms that can last for days, so, if I was to give an answer, I would say winter. Also, I live in Arizona, so you don't have to trust me on this one :>)

rule out metals!\n\ni'm surprised nobody said foam - styrofoam, for example.\n\nor anyhthing else that traps air.\n\nglass.\n\nplastics.
