What is the frozen soil of the tundra called? permafrost savanna canopy understory

Permafrost is like Mother Nature’s icebox, a thick layer of permanently frozen soil found in the tundra regions. This unique phenomenon occurs in areas where the ground has stayed frozen for at least two consecutive years, making it essential for understanding the challenges of climate change—because when it thaws, it can release greenhouse gases like methane into the atmosphere. In real-world applications, permafrost impacts infrastructure in Arctic regions. Buildings, roads, and pipelines often face issues due to the shifting ground as it thaws and refreezes. Engineers have to adopt special construction techniques to ensure safety and longevity, turning permafrost from a mere curiosity into a logistical puzzle in life up north!
