i dont know lol sorry

When rocks grind and squeeze past each other due to tectonic forces, dynamic metamorphism can occur. This process can lead to the formation of mylonites, which are fine-grained rocks with a strong foliation formed from the intense deformation.
When rocks grind against each other, it is called "abrasion." This process occurs when rocks are carried by wind, water, or glaciers, causing them to collide and wear down over time. Abrasion is one of the key processes responsible for the erosion and shaping of Earth's surface.

Stress becomes so great that the rocks of a fault suddenly grind past each other
At these boundaries, the rocks grind and slide against each other, causing earthquakes.
where people grind each other while dancing
Water, Wind or Glacier could make rocks hit and grind each other. This process is termed Attrition.
The abraision of rocks can happen when one rock hits another, when river rocks tumble in the riverbed by fast moving water, by blowing sand particles hitting the rock, and when rocks grind against each other.
tetoic plates grind the grind a slip past each other
At transform boundaries, you will typically find rocks such as fault gouge, mylonite, and cataclasite. These rocks are formed due to intense shearing and fracturing processes that occur at transform boundaries as plates slide past each other horizontally.
