Most people are familiar with three phases of water — solid ({{w|ice}}), liquid (water), and gas ({{w|Water vapor|vapour}}) — and with the fact that an increase in temperature will cause water to change from one state to another. The gas and liquid phases are quite straightforward; however, there is in fact not one single solid phase of water, but a variety of numbered phases ("ice I" through "ice XVI" are currently recognized), several of which are divided into sub-categories. Ordinary, everyday ice that forms on most parts of the Earth's surface is known as "{{w|Ice Ih|ice I<sub>h</sub>}}" ("ice one-h"). Most of the more unusual forms of ice only form under very {{w|high pressure}}. | Most people are familiar with three phases of water — solid ({{w|ice}}), liquid (water), and gas ({{w|Water vapor|vapour}}) — and with the fact that an increase in temperature will cause water to change from one state to another.
