What are joints and faults?
Joints and faults are types of fractures. A joint is a fracture along which no movement has taken place, usually caused by tensional forces. A fault is a fracture or break in the rock along which movement has taken place. One might expect more earthquakes to occur near faults.
What is a joint fault?
- Joint: A break in a rock (crack) in which there is no relative movement of either side across the break. Fault: A break in the Earth in which the rocks on either side of the break have been displaced (vertically and/or horizontally) relative to each other (see pictures below).
What is the difference between a fracture and a joint?
- As nouns the difference between fracture and joint. is that fracture is the act of breaking, or something that has broken, especially that in bone or cartilage while joint is the point where two components of a structure join, but are still able to rotate.
What is the difference between a plate and a fault?
- Plate boundaries can be faults and faults can be plate boundaries. Not all faults are plate boundaries. If rock on both sides of the fault is part of the same plate, i.e. rotating about essentially the same pole, the fault is not a plate boundary. Not all plate boundaries are faults.
