What type of boundary movement occurred at the Indo-Australian plate 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.
Is the Indo-Australian plate divergent or convergent?
convergent
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.
What type of tectonic plate is the Australian plate?
The Australian plate later fused with the adjacent Indian Plate beneath the Indian Ocean to form a single Indo-Australian Plate.

What are the 4 types of tectonic movements?
What are the major plate tectonic boundaries?
- Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
- Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building.
- Transform: shearing; plates slide past each other. Strike-slip motion.
Where is the Indo-Australian plate moving?
Scientists believe that it split from the Indo-Australian plate approximately three million years ago, and today, it is moving 7 centimeters (2.8 inches) northwards and slightly eastwards every year, colliding into the Pacific Plate on its journey.
What happens when Indo-Australian plate collided with Eurasian plate?
About 250 million years ago, India was part of the landmass called the Gondwana land. Eventually, the Indo-Australian plate collided with the Eurasian Plate. This led to the formation of the Himalayas.
What happens when Indo-Australian plate collided with Eurasian Plate?
How is the Australian plate moving?
All of the Earth’s continents float on tectonic plates, which glide slowly over a plastic-like layer of the upper mantle. 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).
What are the 3 main types of plate boundaries?
Divergent boundaries — where new crust is generated as the plates pull away from each other. Convergent boundaries — where crust is destroyed as one plate dives under another. Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other.
What are the 4 different types of plate boundaries?
There are four main types of plate boundary. These are constructive, destructive, conservative and collision margins.
Is Indian Plate still moving?
The Indian Plate is currently moving north-east at five centimetres (2.0 in) per year, while the Eurasian Plate is moving north at only two centimetres (0.79 in) per year.
What happens when Indo-Australian Plate collided with Eurasian Plate?
Where is the Indo-Australian Plate moving?
What direction is the Australian plate moving?
northward
All of the Earth’s continents float on tectonic plates, which glide slowly over a plastic-like layer of the upper mantle. 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 which direction is Australia moved?
north
The continent is moving north by about 7 centimetres each year, colliding with the Pacific Plate, which is moving west about 11 centimetres each year.
What are the 3 mechanisms of plate movement?
The forces that drive Plate Tectonics include: Convection in the Mantle (heat driven) Ridge push (gravitational force at the spreading ridges) Slab pull (gravitational force in subduction zones)
What are 3 types of convergent boundaries?
Convergent boundaries , where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary — oceanic or continental . The types are ocean-ocean, ocean-continent, and continent-continent.
How many types of plate movements are there?
three kinds
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries.
Which direction is the Indo-Australian 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.
Are India and Australia on the same tectonic plate?
But they are widely considered to be two separate plates. The Indo-Australia plate stretches from Australia to India. It also includes the oceanic crust of the Indian Ocean. The northeast side of the Australian plate converges with the Pacific Plate.
How many tectonic plates are there in Australia?
There are a total of seven major tectonic plates which cover nearly 95% of the Earth’s surface.

How many tectonic plates does Australia have?
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.
Is the Indo-Australian Plate oceanic or continental?
Ocean Drilling Program results
…rifting history of the Indian-Australian Plate from East Antarctica and revealed that this submerged plateau—the world’s largest such feature—is of oceanic origin and not a continental fragment, as had been previously thought.
What are the 4 driving forces that influence the movement of plates?
Lithospheric plates are part of a planetary scale thermal convection system.
The forces that drive Plate Tectonics include:
- Convection in the Mantle (heat driven)
- Ridge push (gravitational force at the spreading ridges)
- Slab pull (gravitational force in subduction zones)
What is the movement of tectonic plates called?
The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.
