There are three faults. Normal faults originate from the divergent boundary. Reverse faults originate from the convergent boundary. Strike-slip fault originate from transforming boundary.
What are the three types of fault?
We can differenciate three types of faults,
- Normal fault ⇒ originate from divergent movement
- Reverse fault ⇒ originate from convergent movement
- Stricke-slip fault ⇒ originate from transforming movement
What are the boundary types?
I. Divergent:
This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.
The hot material creates a new seabed between the separating plates, expanding the sea bottom.
II. Convergent.
Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one.
In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices.
The thicker and older plate subduces under the other plate.
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate.
No rocky material is either destroyed or formed.
When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.
The movement breaks the crust and originates pronounced fractures.
