What is a quick sand.how does it work?

It is like wet cement that never dries, and can be as deep as a lake

it varies on how large the beach in question is. larger=more sand

So sand doesn't get caught in your shorts.

you can't get any sand from it. because height means distance above the sand. so for 1400ft depth only we can get sand man

There is only one basic source of sand for a beach, and that is from rivers. Secondarily, some beaches are created by ocean currents such as long-shore migration, where the sand is being moved along the shore to spots it may not have been before. \n\nAs far as river deposition, it will vary according to the sediment load of the river. The Mississippi River moves on average about 436,000 tons of sediment in a day. That one day's deposit of sediment probably has enough sand in it to create a fairly nice beach. Since the sand will most likely be deposited in a mouth bar or somewhere else on the delta, it may not be in the form of a beach, but that process is the source of almost all sand on beaches. Even beaches covered with volcanic sediments like in Hawaii still  most often depend on a river or stream to carry the sediment to the beach. In an extreme volcanic eruption a beach of volcanic ash might be deposited in a few hours. \n\nLong-shore drift creates many beaches, and is a relatively slow process. On some coastlines the wave action variation between winter and summer will make some sandy beaches disappear in winter and come back in summer, so in these cases it may only take a few months to create the beach.\n\nThe part of your question that you didn't ask: How long does it take to create the sand on a beach? That answer could be thousands to millions of years, as rock such as granite has to be weathered and eroded to create the sand grains that make up most sand.

sand is small pieces of rock that has been eroded away from a larger stone.it would take years to get a few pounds of sand from a 25 pound rock but wind rain and snow will break down the rock to produce sand. soil is dirt formed from leaves and twigs from trees. all this will decay and produce soil along with rain and other dying vegetation.go into a densely wooded area and you will find soil.be sure its a hardwood forest.that means maples oaks and other varieties of trees but not conifers, conifers are of the pine family and fir all evergreens.the foilage dropped this fall will take about 2 1/2 to 3 years to decay enough to be soil which is the best for growing flowers and bulbs

I work at my Colleges equestrian center. We have 3 outdoor riding arenas and one indoor arena. We use sand on all the arenas. On the indoor arena and the main outdoor arena that we use for competitions we have rubber mixed in. The rubber is small strips that we get in bulk from a guy that grinds scraps from a toy factory. The rubber is really nice, if you can get some.\n\nDirt would be the cheapest probably, but I think that it would suffer the most from weather and need the most maintenance. \nSawdust floats, is light enough to blow around, and will probably decompose eventually outdoors, so I would stay away from it.\nI assume you mean cinders by ashes. I don't have any idea how well this would work.\nOur coarse sand works well. It is easy to maintain and is not affected too much by the weather. It can get dusty in dry weather, and horses cannot eat off of it because they would ingest the sand. \nWhile it is not perfect, I think that sand is probably your best bet.

Sand dunes like the ones in Colorado's San luis Valley are formed by winds and wind carrying particles have a scouring effect on the earth like a sand blaster. Wearing away at huge rock formations. Over the extremes of geological time this can make huge differences in the rock. Wind can carry small particles great distances as well and redeposit it. Much top soil is lost in this way. Any wind action such as depostion, erosion  or transportation is refered to as eolian in geological terms.

Sand if its a heavy bag... Air if its a speed bag

Ballbearings are dropped as a liquid in a vaccuum,are cooled on the way down, and hit the floor as a solid.\nLater,\nI watched a video on it in my Manufacturing Processes Class while in Mechanical Engineering. I suppose that would be my source, Mr_ Mars...

If you really want ot find out, go to the beach or a playground and walk around in the sandbox barefoot for an hour.  If you are not sore as all frakk when you are done, let me know!  I don't own a pair, but they do sound like a legitimate method.

I think your definition of 'quick' might need rethinking!\nSorry, haven't a clue....

Sand in the ocean deals with water. Sand in the desert would be dealing with wind and heat. Ocean water also contains minerals/salts which may be adhering or tearing away at the sand. The only water desert sand may ever encounter is more than likely the rare rainfall- freshwater, which if anything would help "wash" away any minerals bonding to it. Wet vs. Dry- either way sand gets in places you don't want it... So just keep away from it unless you're gonna superheat the stuff and make glass.. heheh.

Air currents will certainly transport small sedimentary grains.  Dry clay particles are small enough to be held in suspension by the wind.  Sand grains can be moved by a process known as saltation: bouncing grains along the ground or over other grains.  It is by this process that sand dunes migrate.  A storm will move tons of material in this way.  \n\nAs sand grains are moved, they bounce and chip against each other and any exposed rock, breaking off small fragments and rounding the grains in their turn.

I think you'll have a hard time finding even one fatality outside of Hollywood movies. People are even more buoyant in quicksand than they are in water. Consider how much greater the density of sand and water must be than just water. Quartz has a density of 2.6, and water 1, so a quicksand is likely to be nearer to 2.6 than 1. Here is what some researchers found: \n(I quote from msnbc link below) "The density of an average human body is about 62 pounds per cubic foot, which is less than quicksand's 125 pounds per cubic foot." \n Besides that most natural quicksand is not deep enough for anyone to sink completely into it. \n\nWhat you might find are casualties from liquefaction, which is caused by earthquakes shaking soft water-saturated ground, often sandy. However, most of the casualties will be the result of buildings sinking and collapsing into soft wet sand substrates, and are not likely to be from someone actually sinking in sand. \nHere's a good liquefaction website:\nhttp://www.ce.washington.edu/~liquefaction/html/main.html\n\nAnother place where something resembling quicksand causes fatalities are volcanic lahars. These are the consistency of wet concrete and move very quickly down slopes destroying houses and anything in their path. No one gets a chance to walk across one while it is moving, so a fatality related to a lahar is more like being buried under a landslide.  \nHere is an article on lahar hazards:\nhttp://www.agiweb.org/geotimes/apr04/feature_MountRainier.html\n\nHere is an article where researchers found the a mass the equivalent of a human body was impossible to sink in quicksand:\nhttp://msnbc.msn.com/id/9516779/

not sure about sand, but water washes away your natural lubricant so it can hurt alot sometimes and the water can also make you prone to bacteria.
