The plants of the tundra and the permafrost underneath are in balance. Plants growing on the surface absorb solar energy, protecting the permafrost and preventing it from thawing. The permafrost keeps melted water near the surface, where plants need it.
The permafrost keeps melted water near the surface,
where plants need it. However, this balance is fragile. If
the plant cover is damaged, the permafrost can thaw.
Thawing permafrost can make the ground collapse and disturb and deepen the active layer.

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. 85% of Alaska,
Greenland, Canada, and Siberia is sitting
on top of a layer of permafrost, that is
almost a quarter of the Northern
Hemisphere. 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.
