Seasonal ice (Seasonal permafrost)
The thick layer of ice and snow that forms a permanent crust over Alaska and Antarctica is called an ice sheet. Ice sheets are massive expanses of glacier ice that cover large areas of land.

Approximately 68.7% of Earth's freshwater is stored in polar ice caps, glaciers, and permanent snow. This accounts for about 1.7% of the total water on the planet, as the majority of Earth's water (about 97.5%) is saltwater found in oceans. The remaining freshwater is primarily found in lakes, rivers, and underground aquifers.

Antarctica's ice sheet holds about 90% of the earth's store of permanent ice.
The first permanent ice bar is located in Jukkasjärvi, Sweden. It is called the ICEHOTEL and is made entirely of ice and snow, including the bar itself.

Places such as most of Antarctica are covered with a permanent layer of ice. In other places, ice only forms when the temperature drops below freezing. The ice formed when this happens in non-permanent ice because it is only temporary.

No, phase changes in matter are not permanent. They can be reversed by providing or removing energy (such as heat) to the substance. For example, ice can melt into water when heat is applied, and the water can freeze back into ice when it is cooled.
Permanent ice refers to glacial ice or ice sheets that remain frozen year-round and do not melt during the warmer months. This type of ice is typically found in polar regions, such as Antarctica and Greenland, as well as in high mountain ranges. It plays a crucial role in the Earth's climate system by reflecting sunlight and regulating temperatures. Additionally, permanent ice is a significant freshwater reservoir, impacting global sea levels and ecosystems.
