Permafrost is permanently frozen soil, typically found in polar regions.
Think of permafrost like the freezer section at a grocery store. Just as the freezer keeps food frozen and preserved, permafrost keeps whatever it contains (like organic material) in a frozen state for long periods of time.
Tundra: This is a type of biome where the tree growth is hindered by low temperatures and short growing seasons. It's like the 'neighborhood' where permafrost 'lives'.
Thawing Permafrost: This refers to when warming temperatures cause permafrost to melt, often releasing trapped gases like methane into the atmosphere.
Cryosphere: This term encompasses all places on Earth where water is in its solid form, including ice caps, glaciers, and permafrost.
