Friktionsytorna

Friktionsytorna is a geological phenomenon that occurs when a glacier or ice sheet slides over a surface of stationary ice, creating a rotational motion. The term "friktionsytorna" is Swedish, and can be translated to "friction moors" in English.

This process is a type of glacial movement, where the stress between the sliding ice mass and the stationary ice results in a rotational motion. Friktionsytorna is often observed in areas where glaciers have retreated significantly, leaving large, stone-filled depressions, also known as moraines, behind.

When a glacier slides over a stationary ice surface, it creates a frictional force between the two ice masses. If the stress from this friction is large enough, it can cause the glacier to begin rotating around a central point. As the rotation continues, more and more ice is drawn into the rotating motion, resulting in a larger and larger mass of ice moving in a rotational pattern.

Friktionsytorna is often studied by geologists and glaciologists, who use it to understand the movement patterns and behavior of glaciers. It provides valuable insights into the mechanics of glacial movement and can help scientists better understand the effects of climate change on glaciers and ice sheets.
