frozen in ice form
Ice
Yes, ice can be colder than 0 degrees Celsius if it is in a location where the surrounding temperature is below freezing. Ice can exist at temperatures below 0 degrees Celsius as long as the environment is cold enough to keep it frozen.
The different between ice and water is that ice is solid and water is liquid. Under standard pressure, water exists in the solid form as ice when its temperature is below 0° Celsius (32° F). It exists in liquid form between 0° and 100° Celsius.
The frozen part of water is ice. Ice is the solid state of water when it reaches a temperature below 0 degrees Celsius (32 degrees Fahrenheit).
The temperature is below the freezing point of water, causing it to freeze into a solid state like ice.

Water can exist in a solid state as ice, a liquid state as water, and a gaseous state as water vapor.

ice valcanos do exist
Yes, helium can exist in a liquid state at very low temperatures, specifically below -268.9 degrees Celsius.
Water exists in three states: solid (ice), liquid (water), and gas (water vapor).
Carbon dioxide exists in the gaseous state on Earth's surface. It can also exist as a solid (dry ice) at very low temperatures or as a liquid at high pressures and low temperatures.
Antarctica's ice sheet rests on 98% of the continent. It has been said that the ice is so heavy, ". . . In East Antarctica, the ice sheet rests on a major land mass, but in West Antarctica the bed can extend to more than 2,500 m below sea level." Quoted from the Antarctic Ice Sheet entry in Wikipedia. This is some, not most of the ice sheet. Ice shelves exist mostly below sea level.
I know it sounds a little stupid, but supercooling is when water remains a liquid while it is below freezing point. Note, only some waters can do this.
Yes, carbon dioxide (CO2) can exist in a solid state under certain conditions, such as at very low temperatures and high pressures. This solid form of CO2 is commonly known as dry ice.
