WebFractures most often happen when more force is applied to the bone than the bone can take. Bones are weakest when they are twisted. Bone fractures can be caused by falls, trauma, or as a result of a direct blow or kick to the body. Overuse or repetitive motions can tire muscles and put more pressure on the bone. This causes stress fractures.

WebSep 4, 2024 · Cleavage is a profound property that results from a mineral's molecular structure, and cleavage is present even when the mineral doesn't form good crystals. Cleavage can also be described as perfect, good, or poor.
