Transform boundaries happen when two plates move past eachother in different directions or in the same direction at different speeds. When one plate passes another it creates an earthquake. A Canadian geophysicist named Tizo Wilson found a new type of plate boundary called a fault. He also found out that divergent and convegent plates can stop and transform or change into faults. A fault is a place where rocks are broken up because of the crust's movements. A space between where the plates move past eachother is called a transform fault boundary.
