TRIPLE JUNCTION OF PLATES
HISTORICAL BACKGROUND
A Triple Junction is a joint in which three plates meet i.e. the constructive, destructive and conservative plates meet at a point is called Triple Junction. The concept of Triple Junction was first used by W.J.Morgan,Dan McKenzie and Tanya Atwater.
CONCEPT:
A Triple junction is a place in which point three plates meet together.the movement of the three plates are in such ways i.e spreading each other (ridge) ,pushing each other ( trench) and sliding each other( fault).three plates meet at the inter section in their own motion.there are 100 triple junction of 50 plates.
TYPE OF TRIPLE JUNCTION OF PLATES:
There are three type of plate existed i.e. RRR ( all plates are moving away each other) , TTT ( plates lined up at 90 degree angle,pushing together) , FFF ( all plates are sliding each other which is impossible almost).RTF is lined up correctly.Most of the cases junction formed in these manner such as RFF,TTF,TFF,RTT etc.

STABLE JUNCTION AND UNSTABLE JUNCTION:
Stable junction which is maintained its form always whereas Unstable junction which don't remain in same form and changing always occurs.
EXAMPLE
AFAR TRIPLE JUNCTION: The junction of the Red sea, The Gulf of Aden and The East African Rift joint together . This is a RRR triple junction .

| MENDOCINO TRIPLE JUNCTION |
The North sea is located at an old triple junction where three continental plates meet during The Paleozoic era: Avalonia,Laurentia and Baltica.
