WebPermafrost is soil, rock or sediment that is frozen for more than two consecutive years. In areas not covered by ice, it exists beneath a layer of soil, rock or sediment, which freezes and thaws annually and is called the "active layer". [17] In practice, this means that permafrost occurs at an mean annual temperature of −2 °C (28.4 °F) or below. http://arctic.noaa.gov/Report-Card/Report-Card-2024/ArtMID/7916/ArticleID/844/Permafrost-and-the-Global-Carbon-Cycle greene\u0027s funeral home in warrenton nc
