There is no difference. The definition of fault is precisely: a crack in the Earth's crust.
A volcanic vent or fissure is a crack in the Earth's crust where volcanic material such as lava, gases, and ash can escape to the surface. These vents can form as a result of tectonic activity along plate boundaries or within volcanic regions.
A vent is an opening in the Earth's surface where gas or magma can escape, while a rift is a crack or fissure in the Earth's crust where tectonic plates are pulling apart. Vents are typically associated with volcanic activity, while rifts are formed by the movement of tectonic plates.
crust
The mantle is located directly beneath the Earth's crust and is approximately 1,800 miles (2,900 kilometers) thick. The boundary between the crust and the mantle is known as the Mohorovičić discontinuity or Moho.
Cracks in the Earth's crust are faults.
Fault
Tectonic Plate.
A *fault* is a slip or crack in the earths crust.

magma
A crack in the Earth's crust that can lead to an earthquake is called a fault.
The focus is the point in the earths crust where the earthquake originates and the epicentre is the point in the earths surface directly above the focus.
crack in earths crust where two plates are sliding past each other
A crack in Earths's crust along which rocks move. It is created by a transform boundary.
