What tectonic plate is Australia on?
What tectonic plate is Australia on?
Indo-Australian plate
Australia doesn’t sit on the edge of a tectonic plate. However, the Indo-Australian plate, at the centre of which our continent lies, is being pushed to the north-east at about 7cm per year. It’s colliding with the Eurasian, Philippine and Pacific plates, causing stress to build up in the 25km-thick upper crust.
How many tectonic plates does Australia have?
However, recent studies suggest that the two plates have once again split apart and have been separate plates for at least 3 million years and likely longer. The Australian Plate includes the continent of Australia, including Tasmania, as well as portions of New Guinea, New Zealand, and the Indian Ocean basin.
What type of boundary is between Australia and African plate?
divergent boundaries
The African plate is bounded by divergent boundaries, where the plates are moving apart, and convergent boundaries, where the plates are colliding.
Where is the Indian Australian tectonic plate moving?
Plate movements The eastern part (Australian Plate) is moving northward at the rate of 5.6 cm (2.2 in) per year while the western part (Indian Plate) is moving only at the rate of 3.7 cm (1.5 in) per year due to the impediment of the Himalayas.
Is Australian Plate oceanic or continental?
The Australian plate is a continental plate and the Pacific plate is an oceanic plate. At this boundary, the Pacific plate is slowly moving under the Australian plate.
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.
Are Australia and New Zealand on the same tectonic plate?
New Zealand lies at the edge of both the Australian and Pacific tectonic plates. To the south of New Zealand, and underneath Fiordland, the two plates are also moving toward each other but here the Australian Plate is being subducted under the Pacific Plate.
Is the Australian plate convergent or divergent?
The Hikurangi tectonic plate boundary is a convergent boundary. This means that the Australian and Pacific plates are pushing against each other.
Is the African Plate convergent or divergent?
Boundaries. The western edge of the African Plate is a divergent boundary with the North American Plate to the north and the South American Plate to the south which forms the central and southern part of the Mid-Atlantic Ridge.
How India got separated from Africa?
India was still a part of the supercontinent called Gondwana some 140 million years ago. When this supercontinent split up, a tectonic plate composed of India and modern Madagascar started to drift away. Then, India split from Madagascar and drifted north-eastward with a velocity of about 20 cm/year.
