Document Summary

Basal sliding occurs because solid water is denser than its liquid form. Ice at the bottom is under intense pressure which causes it to melt. The liquid water lets the glacier slide down at a rate of m/day rather than cm/day. Phase diagrams map the phase of a substance as a function of temperature and pressure. Increase in pressure favors the solid state in most cases except water. Phase diagram = a map of the state or phase of a substance as a function of pressure (on the y-axis) and temperature (on the x-axis). The major features of a phase diagram. Main features of the phase diagram as regions, lines, and points. Any of the three main regions solid, liquid, and gas in the phase diagram represents conditons where that particular state is stable. Low temperature & high pressure = solid, high temperature & low pressure = gas, intermediate conditions favor the liquid.
