In the Arctic Tundra the frozen subsoil is Permafrost.
This is called permafrost, where soil, rock, or sediment remains below freezing temperatures for two or more consecutive years. It can be found in polar regions or high mountain ranges where the ground is permanently frozen.
Permafrost is subsoil that remains frozen year-round, often found in polar regions. This frozen layer of soil can act as a barrier to water movement and plant root growth, impacting ecosystems and infrastructure development in these areas.
Freeze-thaw weathering occurs when water seeps into cracks in rocks, freezes, expands, and then thaws. This repeated cycle of freezing and thawing weakens the rocks by exerting pressure on the cracks, causing them to widen and break apart. In coastal cliffs, the presence of water from the ocean can accelerate the freeze-thaw process, leading to the gradual breakdown of the rocks over time.
A frozen ground that never thaws is call firnward. Also, permafrost.

A permanently frozen layer of earth. It never thaws out.

Thaws
Place it on a plate and thaw it in the fridge. It's never a good idea to thaw anything at room temperature. The outside of the food will reach room temperature and begin to spoil before the inside of the food thaws. It does take longer to thaw in the fridge but it greatlr reduces the chance of bacteria growing in the food while it thaws.
Place it in the freezer overnight, when it thaws it will be soft & mushy and free of the astringent taste.
The "Active layer" is the few inches of permafrost that thaw in the summer.

yes it can. Tundra is a name given to the permanently frozen ground in the north of Canada and Russia. Tundra NEVER thaws even in the summer.
