# What type of plate boundary is Indo Australian plate?

## What type of plate boundary is Indo Australian 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.

Why does Continental Drift occur?

Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. As the seafloor grows wider, the continents on opposite sides of the ridge move away from each other.

What occurring in the mantle are thought to be the force behind plate tectonics?

The cycle of heating, rising, cooling, and sinking is called a convection current. 2. A version of this same process, occurring in the mantle, is thought to be the force behind plate tectonics.

### 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.

Is Australia moving towards India?

Plate movements The eastern part (Australia) is moving northward at the rate of 5.6 cm (2.2 in) per year while the western part (India) is moving only at the rate of 3.7 cm (1.5 in) per year due to the impediment of the Himalayas.

How is new seafloor formed?

Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed.

#### Where is seafloor destroyed?

subduction zones
You are correct that the seafloor is destroyed at subduction zones, but it is simultaneously being created at mid-ocean ridges. see figure 1 . Figure 1: Seafloor spreading at a mid-ocean ridge(where new crust is being created) and it’s destruction at a subduction zone.

When did the Indian and Eurasian Plates collide?

About 50 million years ago, the Indian Plate and Eurasian Plate began colliding into each other lifting the Himalayan mountain range. To this day, these convergent plate boundaries are still uplifting building new mountain.

How did the Indo-Australian Plate get formed?

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.

## Where was the division of the Indian and Australian plates?

This differential movement has resulted in the compression of the former plate near its centre at Sumatra and the division into the Indian and Australian Plates.

How is the eastern part of the Australian Plate moving?

Plate movements. The eastern part (Australia) is moving northward at the rate of 5.6 cm (2.2 in) per year while the western part (India) is moving only at the rate of 3.7 cm (1.5 in) per year due to the impediment of the Himalayas. This differential movement has resulted in the compression of the former plate near its centre at Sumatra and…
