3. Definition
Is the layer of permanently frozen soil of the very cold regions.
It has a geological age of more than 15 thousand years.

4. Types
The permafrost is divided into two layers.

5. Pergelisol
Molisol
Order of soilsder of soils.
Part of the ground.

6. Where is it located?
In the subsoil of the planet.

7. Gases released because of global warming

8. Methane
There are many important methane reserves
in the permafrost.

9. Carbon
It is estimated that the amount of carbon retained in
the permafrost is roughly twice that of the
atmosphere.

10. Consequences of melting of permafrost

11. Structural damage.

12. Deformations on the roads.

13. Some virus that has been
latent could be released
because of the melting
permafrost.

14. Global warming
Global temperature supposes the loss of a surface of permafrost.
