What plate movement forms trenches?

What plate movement forms trenches?

subduction
In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.

What types of boundaries does the Indian plate have?

As the Indian plate is moving northward relative to the Eurasian plate and collides with it, a convergent boundary is created. On the opposite side, the Indo-African boundary is divergent. The western Indo-Arabian boundary is lateral relative to each other giving rise to a transform boundary.

Is the Indian Plate oceanic or continental?

The Indian plate is both an oceanic and continental plate. The Indian plate used to be connected to the ancient continent of Gondwana, it fractured…

What are the type of boundaries formed between Indian plate and Eurasian plate?

Typically, a convergent plate boundary—such as the one between the Indian Plate and the Eurasian Plate—forms towering mountain ranges, like the Himalaya, as Earth’s crust is crumpled and pushed upward. In some cases, however, a convergent plate boundary can result in one tectonic plate diving underneath another.

How did the Indian Plate form?

This immense mountain range began to form between 40 and 50 million years ago, when two large landmasses, India and Eurasia, driven by plate movement, collided. Artist’s conception of the 6,000-km-plus northward journey of the “India” landmass (Indian Plate) before its collision with Asia (Eurasian Plate).

What type of plate boundary is the Arabian Plate?

transform fault boundary
The Arabian Plate is bounded from the northwest by a left-lateral transform fault boundary, called the Dead Sea Rift, that extends from the northern end of the Red Sea to the Taurus Mountains in southern Turkey through the Dead Sea.

Is the Indian Ocean growing or shrinking?

Since 1880, sea level in the world’s oceans has risen about nine inches. The Arabian Sea and the Bay of Bengal rose four inches more than the world’s oceans — a total of 13 inches to date. The north Indian Ocean is creeping up its coastlines.

How was the Indian Plate formed?

Gondwana broke up as these continents drifted apart at different velocities, a process which led to the opening of the Indian Ocean. In the late Cretaceous, approximately 100 million years ago and subsequent to the splitting off from Gondwana of conjoined Madagascar and India, the Indian Plate split from Madagascar.

How is India formed?

How many tectonic plates are there in India?

Indian plate The Indian tectonic plate is located in the north east hemisphere. It is bounded by 4 major tectonic plates. About 140 million years ago the main landmass on Earth was concentrated together in a super continent called Gondwana which started to break up in four tectonic plates; African, Antarctic, Australian and Indian plates.

Is the Indian Plate underthrusting?

The Indian plate is underthrusting, albeit obliquely, and the Burmese (Myanmar) microplate, the rates of sliding movement varying from sector to sector. This fact implies that the margin of the Indian plate is segmented (Khan, 2004 ).

What caused the rifting of the Indian Plate?

The rifting is thought to be caused by the rising of a mantle plume which caused the Indian plate to drift northwards and resulted in the opening of the Indian Ocean. The velocity of the drifting of the Indian plate northwards was surprisingly high, 18 to 20 cm per year prior to the collision with the Eurasian plate.

Which plate separated the Indian Plate and the Eurasian Plate?

The Tethys Sea separated the Indian plate and the Eurasian plate. The Tibetan block was a part of the Asiatic landmass. India collided with Asia about 40-50 million years ago causing rapid uplift of the Himalayas (the Indian plate and the Eurasian plate were close to the equator back then).
