It would not be good. I don't think that life on earth could be sustained. Ice floats on top of water b/c it is less dense. This prevents the water underneath the ice from freezing. If ice sank, then nothing would stop all water from freezing. Even if these freezing cycles were reversed as earth's temperatures change, it would not bode well for life on earth. (Consider earth's many ice ages)
The ice would sink and the water level will rise.
Additional answer
The ice would, indeed, sink. But this would cause the water level to go down. Think about it. The bit of water that has become ice would be smaller than it was before so the level would go down.
The biggest difference would be that ice would not float, it would sink to the bottom of rivers, streams and lakes. It would make life in these waters difficult to sustain, as the water could freeze solid and kill everything in it.
While ice was melting, it would gradually become lighter and lighter and would stop when it was completely liquid. And the opposite effect would happen if water was freezing to ice, it would gradually get heavier and would stop when it was completely solid.
ice is always more dense then water if you put water in a glass and freeze it it will expand and crack the glass hope you found this helpful.
Additional answer.
Sorry, but ice is never denser than water. Water does expand and may crack a glass when you freeze it, but the expansion means it ends up less dense, not more.
Solid water is ice, which is less dense than liquid water. Which is why icebergs float on the sea. If solid water was denser, icebergs would form on the sea floor instead of floating on top of water.

If it weren't for hydrogen bonds, water would not be a liquid at room temperature, and temperatures common on the earth. Instead it would be water vapor. Also, instead of the unusual property of solid water floating on liquid water, which preserves the lives of aquatic organisms under the ice, ice would be denser than liquid water and would freeze from the bottom up, killing most aquatic organisms.
The fact that water's solid phase is less dense than its liquid phase is important for aquatic organisms because it means that they will be able to live below the ice. This is evident when a lake freezes over to a certain extent while the fish and aquatic life is fine until the ice melts.
Liquid
Water is not denser than any other liquid. Mercury, a liquid at room temperature, has a density of 13.534g/cm3.
The question is deeply flawed. Many metals are denser than many liquids, but many liquids are denser than some metals (and then, of course, there's mercury, which is both a metal and a liquid at room temperature). If all you know about two substances is that one is a liquid and one is a metal and you're forced to bet your life on which is denser ... your odds are probably SLIGHTLY better betting on the metal.

It would float.
The coin would float.
The density of ice is lower than that of liquid water, which means that ice forms from the top of lakes downward, protecting aquatic life in winter.

viscous liquid
No.
That depends on the relative densities of the solid and the liquid. If the solid is denser than the liquid, the solid will sink. If the liquid is denser, the solid will float.
Liquid
An object that is denser than water or another liquid sinks.
an object will float on a denser liquid
