Answer:

Permafrost is ground that continuously remains frozen for two or more years, located on land or under the ocean. Permafrost does not have to be the first layer that is on the ground. It can be an inch to over miles deep into the Earth's surface. Some of the most common permafrost locations are located in the Northern Hemisphere. Almost a quarter of the Northern Hemisphere is underlain by permafrost, including 85% of Alaska, Greenland, Canada and Siberia. It can also be located in the Southern Hemisphere, just on mountain tops. Permafrost frequently occurs in ground ice, but it also can be presented in non-porous bedrock. Permafrost is formed from ice holding all different sorts of soil, sand, and rock combination together.[1]

Answer:

Found under a layer of soil, permafrost can be from three feet to 4,900 feet thick. It stores the carbon-based remains of plants and animals that froze before they could decompose. ... As the global thermostat rises, permafrost, rather than storing carbon, could become a significant source of planet-heating emissions.
