The NE boundary of the Indo-Australian Plate exhibits a uniquely complex and laterally varying set of convergent tectonic styles . Continental collision is occurring along the Himalayan, New Guinea and New Zealand segments of the plate boundary (Fig. 1).
What type of boundary is between Indian Australian and Antarctic plates?
The Indo-Australian Plate and Antarctic Plate Boundary is an active divergent boundary known as the Southeast Indian Ridge. The Southeast Indian Ridge ranges approximately 2000 kilometers across the southern region of the Indian Ocean.
What type of plate boundary is the Indo Australian plate and Pacific plate?
The Hikurangi tectonic plate boundary is a convergent boundary . This means that the Australian and Pacific plates are pushing against each other.
What is happening at the plate boundary where the Australian Plate and the Pacific Plate meet?
New Zealand is on the boundary between the Australian and Pacific tectonic plates. These two plates are being pushed towards each other, but with different results in different parts of New Zealand. To the east of the North Island is a subduction zone, where the Pacific plate plunges down under the Australian plate.
What type of boundary is the Pacific Plate?
The transform plate boundary is a broad zone forming as the Pacific Plate slides northwestward past the North American Plate. It includes many lesser faults in addition to the San Andreas Fault.
What type of boundary is the Eurasian Plate?
The boundary between the North America Plate and the Eurasian Plate is an example of a divergent boundary at a mid-ocean ridge .
Which plate is mostly under an ocean?
Some plates are large enough to consist of both continental and oceanic crustal portions (e.g. the African or South American plates) whilst the Pacific Plate is almost entirely oceanic.
What is causing the Australian plate to move?
Australia's movement is caused by the shifting tectonic plates that make up the earth's surface . The North American plate, by contrast, travels roughly one inch per year.
What is the movement of the Australian plate?
And the plate that Australia sits on has been moving relatively fast, about 2.7 inches a year (northward and with a slight clockwise rotation) . In contrast, the North American plate has been moving roughly one inch a year, though the Pacific plate moves three to four inches a year.
What is the type of boundary between Australian Plate and African plate?
The African plate is bounded by divergent boundaries , where the plates are moving apart, and convergent boundaries, where the plates are colliding.
What evidence shows that the Pacific Plate moving?
The evidence for this motion is pretty convincing: earthquakes : earthquakes occur on the boundaries of the plates as they rub past each other. The motion observed during these earthquakes agrees well with the expected motion.
What kind of plate boundary separates the Caroline plate from the Pacific Plate?
The Caroline Plate is a minor tectonic plate that straddles the Equator in the eastern hemisphere located north of New Guinea. It forms a subduction zone along the border with the Bird's Head Plate and the Woodlark Plate to the south. A transform boundary forms the northern border with the Pacific Plate.
Does Australia sit on a tectonic plate?
Since Australia sits on top of a very stable because geologically old continental landmass in the middle of a tectonic plate (the Australian Plate) with no major active faults, it has far fewer quakes than areas near plate boundaries or major fault lines. Where do earthquakes occur in Australia?
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.
What are the 4 plate boundaries?
Plate Boundaries: Convergent, Divergent, Transform .
Where is the Pacific Plate boundary?
| Pacific Plate | Movement 1 north-west | Speed 1 56–102 mm (2.2–4.0 in)/year |
