The boundaries of the three plates which meet at the Rodrigues Triple Junction are :

  • A.African, Indo-Australian, Antarctic
  • B.Eurasian, Indo-Australian, North American
  • C.Australian, North American, Pacific
  • D.African, Antarctic, Eurasian

Answer: A

The plates are the African, Indo-Australian and Antarctic.

The Rodrigues Triple Junction in the southern Indian Ocean, east of Madagascar, is where three spreading ridges meet: the Central Indian Ridge, the Southwest Indian Ridge and the Southeast Indian Ridge. They separate the African (Somalian) plate, the Indo-Australian (Capricorn and Australian) plates and the Antarctic plate, making it a ridge-ridge-ridge triple junction.

The North American, Pacific and Eurasian plates do not reach the southern Indian Ocean, so the other options are wrong.
