Ice shelf. An ice shelf is a thick floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland and Canada. The boundary between the floating ice shelf and the grounded ice that feeds it is called the grounding line.
A solid consisting of frozen water. Ice forms at or below a temperature of 0Â°C (32Â°F). Ice expands during the process of freezing, with the result that its density is lower than that of water. A solid form of a substance, especially of a substance that is a liquid or a gas at room temperature at sea level on Earth. The nuclei of many comets contain methane ice.
