While there are different types of ice, depending on its crystalline structure and temperature, they are all solid forms of water. Here are some examples:

* Regular ice (Ice Ih): This is the most common form of ice, found in glaciers, snow, and your freezer. It has a hexagonal crystal structure.

* Ice II, Ice III, Ice V, Ice VI, Ice VII, Ice VIII, Ice IX, Ice X, and Ice XI: These are all different crystalline forms of ice that exist at specific temperatures and pressures. For example, Ice VII exists at high pressures, like deep within the Earth.

* Amorphous ice: This form of ice lacks a regular crystal structure and is found in outer space.

So, no matter what form it takes, solid water is always ice.
