That's called the 'permafrost'.
The frozen subsoil of the tundra often prevents the existence of deep-rooted plant life. The low temperatures and lack of nutrients in the frozen soil make it difficult for plants with deep roots to establish themselves in tundra environments.
The permanently frozen area where most Inuit lived is called the Arctic tundra. This environment has a layer of permanently frozen subsoil, known as permafrost, which influences the vegetation and wildlife that can thrive there.
Seeds need oxygen for the process of germination, which is limited in subsoil due to poor aeration. Subsoil also tends to be compacted, making it difficult for seed roots to penetrate and access nutrients and water needed for growth. Additionally, subsoil may lack the necessary microbial activity and organic matter to support seed germination and growth.
permafrost. It is primarily found in the Arctic regions of Asia, such as Siberia and parts of Alaska, Canada, and Greenland. Permafrost plays a critical role in shaping the landscape and preserving ancient organic matter.

permafrost
Permafrost is a layer of soil, rock, or sediment that remains frozen for at least two consecutive years. It is found in areas with very cold climates, such as polar regions, and prevents the ground from thawing completely even during the summer months.

An area with frozen subsoil is known as permafrost. Permafrost is permanently frozen soil, rock, or sediment that remains below 0°C for at least two consecutive years. It is typically found in polar regions and high mountainous areas.
