Which type of convergent plate boundary formed 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 type of plate boundary is common in Indonesia?

Sumatra is at the boundary between two tectonic plates. The ocean floor southwest of Sumatra is part of the Indian/Australian plate, while Sumatra and the other islands of Indonesia and Thailand are part of the Eurasian plate (see Figure 1).

How was Indonesia islands formed?

The Indonesian archipel- ago formed over the past 300 million years by reassembly of fragments rifted from the Gondwana supercontinent that arrived at the Eurasian subduction margin. The present-day geology of Indonesia is broadly the result of Cenozoic subduction and collision at this margin.

Which convergent boundary may form an island?

As the sinking plate moves deeper into the mantle, fluids are released from the rock causing the overlying mantle to partially melt. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.

Is Indonesia on a convergent plate boundary?

Indonesia sits along the “Pacific Ring of Fire” where several tectonic plates collide and many volcanic eruptions and earthquakes occur.

Covering an area of roughly 287,000 square miles, Borneo is the third-largest island in the world. It is divided into four political regions: Kalimantan belongs to Indonesia; Sabah and Sarawak are part of Malaysia; a small remaining region comprises the sultanate of Brunei.

What are three examples of convergent plate boundaries?

Three types of convergent boundaries are recognized: continent‐continent, ocean‐continent, and ocean‐ocean.

  • Continent‐continent convergence results when two continents collide. …
  • Ocean‐continent convergence occurs when oceanic crust is subducted under continental crust.
