Mechanical weathering (physical weathering) is weathering by physical means. Some types of physical weathering are:-Ice- frost action, ice weathering: Water will fill a crack and expand when frozen.-Abrasion- the grinding and wearing away of rock surfaces through the mechanical action of other rock or sand particles.HOPE THIS HELPS! :)

The dropping off of rocks after erosion occurs.

Hmmm...So if you can't cut your hair, maybe try to put it in a messy ponytail and see if that is cute. Or you can braid two braids and have pigtails. It all depends on how long your hair is.
