The formation of the permafrost patterns results from gravity and a peculiar physical phenomenon
A curious property of permafrost can be partially explained using the physics of non-Newtonian fluids: this is "oobleck".
Researchers have used mathematical and physical models, as well as remote sensing technology, to explain the formation of solifluction features, also known as terraced or lobed patterns, found on Arctic hillslopes. These features are formed by the slow movement of thawing permafrost, which behaves like a non-Newtonian fluid. The team, led by Glade, found that the features are similar to waves formed in a fluid called Oobleck, a mixture of cornstarch and water.
The model has limitations, as it only reflects the rheological properties of the soil and does not account for factors such as topography and vegetation. The study was published in AGU Advances.
