Lava or Magma is rock in its molten state.
It depends on the type of rock and the conditions. Generally, ice has a lower density than most rocks, which is why ice floats on water. Rocks vary in density based on their composition and can be denser than ice.
When water rubs against rock, tiny particles of the rock slowly break off and the rock gets smaller. When ice does the same, it does the same thing but a little faster.
no. Density of ice is more than of water...we can understand from ice sinking in water drinks... Edited by Dr.J. : How is it possible for the density of ice to be more (greater) than that of liquid water if ice FLOATS on lakes and rivers? Clearly, the density of ice is LESS than that of liquid water.
If you freeze a sample of liquid water it should expand but still weigh the same amount. Water is denser than ice so by volume liquid water is heavier than water ice, thus ice floats.
"Ice water" could either refer to water that has been chilled to the freezing temperature or just a container of water with ice floating in that is close to (but still above) that freezing temperature. Ice can be no warmer than the freezing point but can certainly be colder. If the solid (ice) is in equilibrium with the liquid ("ice water"), the ice will NOT be cooler, but as noted, if they are not really in equilibrium, you would expect the solid (ice) to be colder than the liquid water rather than the other way around.

the ice expands the rock
The Solid Form of Water that breaks rock is called "ice".

It does what all water does when it freezes: expands. This will crack the rock.
Water is stronger than rock.
believe it or not, sea salt is more water soluble.
Ice is lighter (less dense) than water. Which is why ice can float on the surface of water.

No, ice is not a rock. Ice is a solid form of water that forms when water freezes at or below 0 degrees Celsius. Rocks, on the other hand, are naturally occurring solid aggregates of minerals or mineraloids.
Ice and water can break up rock through a process called frost wedging. Water seeps into cracks in rocks, freezes, and expands, causing the rock to fracture. Over time, repeated freezing and thawing can eventually break the rock into smaller pieces.
