The island of Java lies on a convergent plate boundary where the Australian plate subducts beneath the Sunda plate at the Java Trench at a rate of approximately 67 mm/yr.
What type of convergent plate boundary is the Indonesian island?
Indonesian archipelago was formed due to convergence between Sunda oceanic plate (part of the Eurasian plate) and Indo-Australian plate whereas Philippine archipelago was formed due to convergence between Sunda oceanic plate and Philippine Sea plate. In ocean-ocean convergence, two oceanic plates converge or collide.
What is the type of plate movement which formed the islands of Indonesia?
Studies of seismic and geologic profiles across the Sumatra, Java and Timor arc—trench systems reveal that large islands of the inner volcanic arc with silicic and intermediate volcanism, such as Java and Sumatra, were formed due to subduction of oceanic plate under a thick and old continental crust.
Which is the best example of a convergent plate boundary?
Answer: The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate.
