Ice molecules can exhibit seventeen or more different phases ( packing geometries ) that depend on temperature and pressure. When water is cooled rapidly (quenching), up to three different types of amorphous ice can form depending on the history of its pressure and temperature. When cooled slowly correlated proton tunneling occurs below 20 K giving rise to macroscopic quantum phenomena . Virtually all the ice on Earth's surface and in its atmosphere is of a hexagonal crystalline structure denoted as ice I h (spoken as "ice one h") with minute traces of cubic ice denoted as ice I c . The most common phase transition to ice I h occurs when liquid water is cooled below 0 °C ( K , 32 °F ) at standard atmospheric pressure . It may also be deposited directly by water vapor , as happens in the formation of frost. The transition from ice to water is melting and from ice directly to water vapor is sublimation .

Sea ice is found in remote polar oceans. On average, sea ice covers about 25 million square kilometers (9,652,553 square miles) of the earth, or about two-and-a-half times the area of Canada. Because most of us do not live in the polar regions, we may live for several decades and never see sea ice. Although it may not directly affect us, it is a critical component of our planet because it influences climate, wildlife, and people who live in the Arctic.
