![]() ![]() Oceanic plates are colder and denser than the mantle beneath them, so they sink downward into it at subduction zones.Ī few rock core samples, with the sample orientation line marked on their sides. Tectonic plates make up the surface of Earth, and they're constantly in motion-drifting at the imperceptibly slow pace of just a few centimeters each year. By decoding the magnetic records preserved inside them, we hoped to reconstruct the geography of ancient landmasses-and revise the story of the creation of the Himalayas. Our team of geologists traveled here to collect rocks that erupted as lava more than 60 million years ago. It marks the boundary where two tectonic plates fused together and an ancient ocean disappeared. Known as a suture zone, it's only a few kilometers wide and consists of slivers of different types of rocks all sliced together by fault zones. This area also contains a different type of boundary, a narrow sinuous geological structure that stretches along the length of the Himalayan mountain range. It's a reminder how close we are to the long-disputed borders between India, Pakistan and China which lie on the ridgelines just a few miles away. It does not store any personal data.The muffled soundscape of the spectacular Himalayan wilderness is punctuated by a military convoy roaring along the Khardung-La road below.

Plate boundaries are commonly associated with geological events such as earthquakes and the creation of topographic features such as mountains, volcanoes, mid-ocean ridges, and oceanic trenches. The location where two plates meet is called a plate boundary. This movement started about 70 million years ago and has been going on up to the present day. They were formed when the Indian subcontinent, which was originally a part of the southern landmass, drifted to the north and crashed into Asia. The Himalayas belong to the youngest mountain ranges in the world. The Himalayan mountain range and Tibetan plateau have formed as a result of the collision between the Indian Plate and Eurasian Plate which began 50 million years ago and continues today. The formation of the Andaman and Nicobar Islands in the Bay of Bengal and the Arakan Yoma highlands in Myanmar is also the result of this continental collision. The formation of the great Himalayas is basically the result of a continental collision called orogeny along the convergent wall of the Eurasian Plate as well as Indo-Australian plate. What caused the formation of the Himalayas? They cover approximately 1,500 mi (2,400 km) and pass through the nations of India, Pakistan, Afghanistan, China, Bhutan and Nepal. The Himalayas stretch across the northeastern portion of India. 225 million years ago (Ma) India was a large island situated off the Australian coast and separated from Asia by the Tethys Ocean. ![]() There are some sub-varieties but these are the main ones. Are the Himalayas an example of a divergent plate boundary?ĭivergent (Mid-Atlantic ridge, The Rift Valley), Convergent (The Andes, The Himalayas) and Transform (San Andreas fault, Dead Sea Transform). The northerly side of the Plate is a convergent boundary with the Eurasian Plate forming the Himalaya and Hindu Kush mountains, called the Main Himalayan Thrust. What kind of plate boundary is the Indian Plate boundary with the Himalayan mountains? 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. What type of plate boundary exists in the Himalayas? 2 Are the Himalayas an example of a divergent plate boundary?.1 What type of plate boundary exists in the Himalayas?. ![]()
