Answers
Permafrost is a permanently frozen layer below the Earths surface. It consists of soil, gravel, and sand, usually bound together by ice. Permafrost usually remains at or below 0C (32F) for at least two years. Permafrost can be found on land and below the ocean floor.
Permafrost is ground (soil or rock and included ice and organic material) that remains at or below 0 °C for at least two consecutive years. ... Temperature measurements are also required to determine the status of the permafrost. Permafrost that is warm and/or warming is in danger of thawing.
Permafrost can be found on land and below the ocean floor. It is found in areas where temperatures rarely rise above freezing. This means permafrost is often found in Arctic regions such as Greenland, the U.S. state of Alaska, Russia, China, and Eastern Europe.
