As the Indian plate is moving northward relative to the Eurasian plate and collides with it, a convergent boundary is created. On the opposite side, the Indo-African boundary is divergent. The western Indo-Arabian boundary is lateral relative to each other giving rise to a transform boundary. It was previously thought that the Indian and the Australian plates formed one single plate as there is no clear type of boundary but recent seismologic evidence suggests that the two plates will have a transform boundary as the drift velocities of these two plates are different even if the general direction of motion of the two plates is similar.
