The term hard water is usually used to describe water which has a relatively large amount of mineral content dissolved in it. If you are asking about solidified water, then that is always referred to as ice. You can do lots of things with water, for example you can add Gelatin to it and make jello, but if it's just water, and it has solidified, then that is called ice, and nothing else.

Calcium and magnesium are the main metals found in hard water areas. These minerals dissolve in water as it passes through rocks like limestone and chalk, leading to the formation of hard water.
The most common constituents that make water hard are magnesium and calcium ions, since these form only very slightly soluble salts with anions in soap. The other alkaline earth metal cations have the same effect, but occur less commonly.

Calcium and magnesium are minerals commonly found in higher concentrations in hard water compared to soft water. These minerals can contribute to the formation of limescale in pipes and appliances.
Calcium is the element found in both bones and hard water. In bones, calcium provides strength and structure, while in hard water, it is dissolved in the form of calcium ions.
Oxygen is not always in the form of a gas. It can be found in liquid form as a component of the compound called water. It can be found in solid form as a component of rust (iron oxide) and many other compounds.Free oxygen is found as a gas on the planet earth because the temperate of the planet's surface and atmosphere are well above the boiling point of molecular oxygen, which is -297 F or -183 C. We use oxygen in liquid form as part of the fuel of some rockets. Then we have to work very hard to condense it out of the air.

A scum forms when soap is used in hard water. This occurs because the calcium and magnesium ions in the hard water react with the soap to form insoluble salts, which precipitate out as a scum.

YES, it's is the calcium that makes the water "hard". That is why you use a cleaner that has a calcium remover in it to get those hard water stains off.
in experince, i have never came accross hard water, but if it helps it goes relativly hard when it is in ice form. :)

Nodules are hard to mine because they are found in very deep water
