The seas would rise.

It melts just because of the effect of heat on ice
They could all disappear if the temperature of the earth rises enough.
Ice melt is made up of chemicals that are intended to melt ice. These chemicals often include salt as well.
fire does. ice needs to take time to effect your entire body.
no
Water tend's to crack and melt the ice, depending on the temperature it's at, it could freeze almost instantly.
greenhouse
Sea levels will rise.
The salt will quickly melt the ice
Antarctica is a continent, one of seven on earth and its soil comprises about 10% of the earth's surface. The vast ice cap on Antarctica could melt, but continents do not melt.
It melts just because of the effect of heat on ice
Yes, salt dissolves in water and when it dissolves, some heat is produced that causes more ice to melt and dissolve more salt. Salt lowers the freezing point of water so the water that melted from the heat of solution will not re-freeze. Salt has little effect on the ice on a road, initially. Pressure on the ice from traffic causes the ice to melt. If salt crystals have been sprinkled on the ice the effect is improved. Oil, on the other hand, does not dissolve in water to any effective extent at all. It would have no effect on lowering the freezing point of water. It could insulate the ice from being heated by warm air or if the oil is very dark in color, it could absorb heat from solar radiation and melt the ice. That effect is what causes ice to melt when soot and cinders are sprinkled on it.
Yes, it could melt on ice.
Yes, ice melts from the outside which means the wider surface area, the faster it will melt!
A fire (heat!)
no, the earth is going the its cycle. The earth was one in an ice age and got really hot to melt all the ice. So it just happening now to us.
