What type of boundary is the Australian and Pacific Plate?

What type of boundary is the Australian and Pacific Plate?

convergent boundary
The Hikurangi tectonic plate boundary is a convergent boundary. This means that the Australian and Pacific plates are pushing against each other. There are two kinds of plates – oceanic and continental plates.

What kind of plate boundary is found between Australian and Pacific over New Zealand?

The Alpine Fault is the dominant structure defining the Australian-Pacific plate boundary in the South Island of New Zealand. It runs as a single structure for over 500 km between the Puysegur Trench in the south and the Marlborough Fault System in the northeast.

What type of plate boundary is the Pacific Plate?

transform plate boundary
A transform plate boundary developed where the Pacific Plate was in contact with the North American Plate and the volcanism ceased in central California.

What plate boundary is Australia on?

Because plate tectonic boundaries contain both oceanic and continental crust, the Indo-Australia plate contains the following features: Both countries of India and Australia are situated on the Indo-Australia plate.

Which type of boundary is between Pacific Plate and Antarctic Plate?

The southern side is a divergent boundary with the Antarctic Plate forming the Pacific–Antarctic Ridge.

Is Australia on a tectonic plate?

The Indo-Australian Plate is a major tectonic plate that includes the continent of Australia and surrounding ocean, and extends northwest to include the Indian subcontinent and adjacent waters. It was formed by the fusion of Indian and Australian plates approximately 43 million years ago.

What type of plate boundary occurs between the North American and Eurasian plates?

Mid Atlantic Ridge
The Mid Atlantic Ridge, like other ocean ridge systems, has developed as a consequence of the divergent motion between the Eurasian and North American, and African and South American Plates.

Is the Antarctic Plate oceanic or continental?

The Antarctic Plate includes continental crust making up Antarctica and its continental shelf, along with oceanic crust beneath the seas surrounding Antarctica.

Is the Pacific Plate convergent?

The Western part of the Pacific Plate is subducting under the Philippine Sea Plate, forming a convergent boundary. Forming a mostly convergent boundary, it subducts under the other, just north of New Zealand, forming underwater trenches.

What type of plate boundary is in the Pacific Northwest?

subduction zone
For about 200 million years the Pacific Northwest region has been at an active plate boundary, specifically an ocean-continent convergent plate boundary with a subduction zone. Subduction has created most of the volcanoes and mountain ranges of the Northwest.

What type of boundary is between Indian Australian and Antarctic plates?

divergent boundary
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.

Is Australian plate a primary plate?

These divisions are inevitably somewhat arbitrary, but by convention we recognise seven main or “primary” tectonic plates: these are the African Plate: Antarctic Plate, Eurasian Plate, Indo-Australian Plate, North American Plate, Pacific Plate, and South American Plate.

What type of plate boundary is the Pacific Plate and Australian Plate?

The boundary between the Pacific Plate and Australian Plate is marked by volcanism, earthquakes, and different and unique topography. The border of these two plates is composed of a mix of transform and convergent boundaries along the Eastern edge of the Australian plate, with both divergent and convergent boundaries along the Northern edge.

What type of plate boundary is the Alpine Fault?

The Alpine Fault marks a transform boundary between the two plates, and further south the Indo-Australian Plate subducts under the Pacific Plate forming the Puysegur Trench. The southern part of Zealandia, which is to the east of this boundary, is the plate’s largest block of continental crust.

What direction is the Australian Plate moving?

The Australian Plate is moving in a North to Northeastern direction at a speed of approximately 7 cm /year (although the continent of Australia only shifts by approximately 5.6 cm/year). Meanwhile, the Pacific Plate moves towards the Northwest at a speed of also approximately 7 cm/year (at least the speed of the movement of Hawaii).

What type of plate boundary is the TVZ?

The TVZ occurs because of New Zealand’s position on top of the plate boundary between the Pacific plate and the Indo-Australian plate. This forms part of the so-called ‘ring of fire’, which is a series of volcanoes around the edges of the Pacific Plate.
