Permafrost and Periglacial Processes (journal)

Permafrost is permanently frozen ground, typically found in polar regions and high mountains. It remains below zero degrees Celsius for at least two consecutive years. Periglacial processes involve the physical changes and features that occur in areas surrounding permafrost, such as frost heave, which pushes soil upwards, and solifluction, where saturated soil flows downhill. These processes shape landscapes, create patterns in the ground, and influence ecosystems. Understanding permafrost and periglacial processes is crucial, especially as climate change threatens to thaw permafrost, releasing greenhouse gases and impacting global environments.
