its not
Well, its not "generally" put on ice, but when it IS used its put down to suppposedly increase traction and reduce slipping on sidewalks and roads.

How long does it take sand to melt ice?
It depends on the temperature of the sand and the ice! Sand does not dissolve in water to any significant extent, so that mixing sand with ice will not lower the melting point of the ice. If there is a sufficient amount of sand and it has a temperature above the freezing point of water, sand will eventually melt ice by heat conduction from the sand to the ice. If the sand has a lower temperature than the ice, mixing them will never produce melting of the ice.
Why do people put salt and sand on the road what do they do individually?
The salt will melt the snow and ice, but can really damage the roads. The Sand creates more traction and will not cause damage to the roads.
Does the sand melt the ice?
Sand doesn't melt ice to any noticeable degree. However, sand picks up heat from sunlight better than pure ice, which can speed up melting a little bit.
What melt ice faster sand or clay?
Sand melts ice faster because it has salt and the salt makes it melt alot faster than clay.
How can you drink your urine for survival?
you can find some sand and get some cloth and pee and the cloth with the sand and start sucking @the bottom of the sack of sand don't put you mouth on the sand put your mouth on the cloth with the sand in it and you with be drinking you Owen urine?it taste just like water?
What happens when sand is scattered on icy roads?
The sand helps melt the ice. I did an experiment. I put three ice cubes in 1 bowl without ice. The other bowl had salt and ice. The one with salt melted the quickest.
When driving on a slippery surface such as snow or ice you should?
Put some sand on it to increase friction!
Does sand melt ice?
Sand abosorbs light better then ice. So the heat melts the ice.
Why does sand on ice keep you from slipping?
because sand makes friction from the ice

Why does ice melt faster in sunshine if sand is sprinkled on it?
Heat •Sand can melt ice if it is heated naturally from the sun or a warm temperature--just like any other substance that is warmer than ice. The actual texture of sand does not cause ice to melt, which is why you would have to place a blanket of warm sand on ice for it to melt. The sand could similarly cause the ice to melt faster if it was placed on ice and then in direct sunlight, as sand heats very quickly. Prevention •Though sand cannot melt ice on its own unless it is heated by the sun, it may prevent more ice from forming. Placing a thick layer of sand on icy roads may reduce the amount of ice that can form on top of the sand. This is because sand particles are extremely small and mobile, making them hard to keep down with substances such as ice. Elements such as wind or rain may cause sand to move continuously, keeping the surface of the road from becoming substantially covered in ice. Though it may not prevent any ice from forming on the road, it can slow down the buildup. Misconceptions •Because many highway patrols place sand on ice during the winter, many people have come to believe that it is put there to melt the ice. This is not the case. The sand is put there to provide some traction on the ice. Without sand, an icy road would be extremely slick, leading to numerous accidents. However, by placing a rough layer of sand on the ice, the highway patrol is able to provide a make-shift form of gravel during cold spells. People mistakenly think that sand and salt perform the same functions on ice, but they do not. When salt is placed on an icy road, it is done so to melt the ice, creating a slick-free road. If salt is mixed into the sand, however, it may be able to melt the ice to a certain degree.
Is there sand on europa?
no. no sand on europa mainly ice

Why do they use sand on icy roads?
Ice is slick; sand is not. Sand spread over the ice and snow make it less likely that cars will slide uncontrollably and get into accidents.
Does the sand melt the ice?
Sand doesn't melt ice to any noticeable degree. However, sand picks up heat from sunlight better than pure ice, which can speed up melting a little bit.
How could you model the way that glaciers move in nature?
you could use a large ice cube , make a hill out of sand then put the ice cube at the top and see if it slowly slides down.
Is a glacier a mass of ice or a mass of sand?
The answer to the question is a glacier is a mass of ice.
