Lava or Magma is rock in its molten state.
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.
You don't use rock salt in ice cream, unless you want salty ice cream. You use rock salt (though table salt or sea salt would work just about as well) in the freezer to get it colder than you could with a mixture of ice and water.
Rain water seeps into any cracks in the rock. When the water freezes in winter, the ice expands and the force can be strong enough to split the rock.
Ice Air is less dense than water, so water sinks below air. A rock is more dense than water, so it sinks in water and air. And helium, which is less dense than air, rises in air and in water.
the ice expands the rock
The Solid Form of Water that breaks rock is called "ice".

Water expands as it freezes. So if water gets into a crack in a rock, and then freezes, the expanding ice pushes against the rock and can cause the rock to break.
weathering happens when bits of rock are moved by water or ice true or false
When a piece of ice is wedged into a rock, it expands (because water expands when it freezes). As the ice expands, cracks are formed in the rock.
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, snow is flakes of solidified water (ice).
It does what all water does when it freezes: expands. This will crack the rock.
Water is stronger than rock.
Ice is lighter (less dense) than water. Which is why ice can float on the surface of water.
believe it or not, sea salt is more water soluble.
