Why does dust stick together to make lint (and clumps) and sand doesn't?

1) Sand grains are too heavy compared to bits of dust. Gravity overcomes cohesion and adhesion in their case. Dust, on the other hand, is light enough to get blown around by the breeze your legs create when you walk through the room. As the bits are blown around, they collide with each other and get hung up on each other. As sand gets blown around, it just falls down again.\n\n2) Also, unlike the building blocks of dust bunnies, sand is not dead cells shed from humans and other animals. Most of the dust your body produces probably has enough skin oils to create a little bit of stickiness.

In order for snow to form the air must be supercooled. The process of snow formation starts w/ the Bergeron Process. This is also known as cold cloud precipitation.\n\nTiny ice particles form around condensation nuclei aka aerosols (pollen, dust, ash, salts, etc.) in the upper atmosphere.\n\nThey grow larger & larger until they can no longer be supported & gravity takes over.\n\nThe reason why the whole cloud won't freeze is b/c they are individual ice crystals. There is no way that they could stay suspended long enough to grow large enough to stick together.\n\nSo your answer is gravity takes over!

If it hits sand, it will often make glass.  It makes the ground very hot for a short time, having so much moisture around it draws the heat away quickly.

Liquefaction occurs when the structure of a loose, saturated sand breaks down due to some rapidly applied loading. As the structure breaks down, the loosely-packed individual soil particles attempt to move into a denser configuration. In an earthquake, however, there is not enough time for the water in the pores of the soil to be squeezed out. Instead, the water is "trapped" and prevents the soil particles from moving closer together. This is accompanied by an increase in water pressure which reduces the contact forces between the individual soil particles, thereby softening and weakening the soil deposit.  \n      Observe how small the contact forces are because of the high water pressure. In an extreme case, the porewater pressure may become so high that many of the soil particles lose contact with each other. In such cases, the soil will have very little strength, and will behave more like a liquid than a solid - hence, the name "liquefaction".

Pick up a can of "dust off" it is compressed air.  If the dust got in, it should be able to be blown out, or at least off to the side where it isn't in your drawing.  I personally would just dissassemble the screen carefully.  They do come apart.  But, if you are not sure of yourself.. then I would try the air.  It is non conductive, non abrasive and should do the job for under $5 and a few seconds.\nGood luck.. TonyD

As a kid I thought that if I kicked up a lot of dust and got it as high as I possibly could, that it would cause precipitation in my town.  So on below freezing days, it would snow.

It is most likely the court. If it is dirty/dusty, the dirt or dust sticks to the bottom of the shoe, making it loose traction. Try just talking a wet cloth and wiping the bottom of the shoe before the game. If that doesn't work, use that Sole Roller. It's almost like a lint roller but it's for shoes. I used to have one and it worked really well.

It is the dry air which causes such a problem.  Check for the humidity levels as undue dryness will aggravate your problem.

A dust storm happens when loose earth or sand is picked up by winds usually in excess of 30mph. It's not really possible to make a chart of a sandstorm as such, but if you reference "The Dust Bowl" you might find something that might be of use

YOU ARE RIGHT. THE SURFACE OF THE PARTICLE OR OBJECT HAS TO BE UNEVEN OR ROUGH SURFACE

Huh?  Dust does not affect charge coupled device operation.\n\nPlease clarify your question

Either your blower isn't pushing enough air through, so the coils overheat, or you have a deffective thermal switch. The thermal switch in question should be close to your elements, and is a safety to kick them out if they get too hot. So change your air filters, if it don't work, replace the thermal switch. If you know an electrician, have him check to see if there is voltage going through the thermal switch when the elements are out without a reason. Same thing for a dryer, if you lose your heat, it's either a broken element, or a thermal switch, or your lint catcher is plugged, preventing the air from cooling the elements. I have seen lint catcher plugged below the screen, enough lint to make a small pillow.

We use the heavier sand, not the fine playsand, it's a little heavier(probably more rock in it). It seems to hold up better.

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.

Erosion breaks up igneous and metamorphic rocks, and the particles build up to create sedimentary rocks.  \n\nHope this is helpful.

Sand.  Hahaha...no really, send them baby wipes.  There is so much dust and sand there that they are used for everything.

Place the sand on a piece of paper, then place the magnet underneath, then the tilt the paper, that way the iron will stay where it is but won't just stick to the magnet!!
