    According to geological investigations, as early as 2 billion years ago, the vast area of the current Himalayas is a vast ocean, called the ancient Mediterranean, it has experienced a long geological period, and has lasted until the end of the Cenozoic early Tertiary period 30 million years ago, when the crustal movement in this area, the general trend is continuous decline, in the process of decline, the ocean basin has accumulated marine sedimentary rock layers up to 30,000 meters thick. By the end of the Early Tertiary period, a strong orogeny in the earth's crust, known geologically as the "Himalayan Movement", caused the region to gradually uplift and form the most majestic mountain range in the world. Geological expeditions have shown that the tectonic movement of the Himalayas has not yet ended, and only after the Quaternary glaciation, it has risen by another 1300 to 1500 meters.

    It's still slowly rising.

    The Himalayas are part of a chain of Eurasian mountain ranges from the Alps to the Southeast Asian mountain ranges, all of which were formed over the past 65 million years by global plate tectonic forces that caused the massive uplift of the Earth's crust.

    Your statement is wrong! The reason for the formation of the Himalayas is: according to the research of geologists, 70 million years ago, it was still a vast ocean, and 30 million years ago, due to orogeny, the Indian Ocean plate in the south and the Eurasian plate in the north collided with each other, overlapping and squeezing, so that the Himalayas continued to rise.

    By 3 million years ago, it had risen to 3,500 meters, and in the last 100,000 years, it has risen even faster, with an average height of more than 6,000 meters today, and it continues to rise. The Himalayas suddenly uplifted, forming a volley barrier that blocked the northward movement of warm and humid air currents from the Indian Ocean, resulting in a cold and arid climate in Qinghai-Tibet, which affected the northwest of the country.

    Between the tectonic plates, the Himalayas are rising in elevation.

    The Himalayas are located at the junction of the extrusion and collision of the Eurasian plate and the Indian Ocean ridge plate, and the plate is in constant motion, and the extrusion and collision of the plate makes the Indian Ocean plate subduct under the Eurasian plate, so that the altitude of the Himalayas continues to rise.

    The Tibetan Plateau is the highest plateau in the world, with an average altitude of more than 4,500 meters, and is known as the "Roof of the World". There is the world's highest mountain, Mount Everest, and there are 14 peaks above 8,000 meters above sea level in the world, all of which are located on the Qinghai-Tibet Plateau. It is also the youngest plateau in the world.

    It is hard to imagine that the Tibetan Plateau was once buried deep under the sea, and the Himalayas have not stopped rising, with an average of millimeters per year. In the layers of rock formations, geologists have unearthed a large number of dinosaur fossils, terrestrial plant fossils, three-toed horse fossils and many ancient sea creatures fossils. Faced with these fossils, geologists' minds go back to distant geological time.

    Two or three hundred million years ago, the Qinghai-Tibet Plateau used to be a vast ocean, and then due to the strong crustal movement, the folded Zou mountain system of the Paleozoic Era was formed, and the ocean disappeared, and the ancient Qilian Mountains and ancient Kunlun Mountains were produced. During the Mesozoic Era, long-term weathering leveled these mountains during the Mesozoic Era. After the Cenozoic, the earth's crust became active again, and those ancient mountains rose violently and became high mountains again.

    More than 40 million years ago, the Himalayas were a vast sea of descent, where creatures of all ages were buried in sedimentary rock formations. As the Indian Ocean plate moved northward and collided with the Eurasian plate, the ancient sea in this region was squeezed, and the Himalayas gradually rose from the bottom of the sea, with a large uplift of the plateau, becoming the "roof of the world". Fossilized sea shells in the Himalayas are evidence of tectonic changes.

    Summary. The Himalayas are related to Tibet, it stands on the southern edge of the Qinghai-Tibet Plateau, from the Nanga Parbat Peak in the northwest of the Qinghai-Tibet Plateau in the west, to the Nanga Bhava Peak at the sharp bend of the Brahmaputra River in the east, and the peak of Zui is Mount Everest. The remnants of the sea water are about 600 meters deep underground, and after hundreds of millions of years of extrusion and high temperature, the minerals in the ground are combined with sea salt to form salt fossils, which are Himalayan mineral salts, which are what we call Himalayan pink salt, Himalayan pink salt or Himalayan crystal salt.

    Geological expeditions have confirmed that as early as 2 billion years ago, the vast area of what is now the Himalayas was a vast ocean, part of the ancient Mediterranean. The Himalayan region has experienced a long geological period until the end of the early Tertiary period of the Cenozoic Era, 30 million years ago, when the earth's crustal movement in this region was generally characterized by a continuous decline, in which the basin was filled with marine sedimentary rocks more than 30,000 meters thick.

    Fossils of ancient marine flora and fauna have been found on the steep cliffs of the Himalayas or in the deep valleys. These include: trilobites, pencils, gastropods, brachiopods, nautilus, ammonites, flap gills, corals, bryozoans, sea urchins, sea lilies, mesozoans, foraminifera, seaweeds and ichthyosaurs.

    These fossils illustrate that the Himalayan region was once a vast ocean. It emerged from the ancient sea, and the result of the rising crust caused all this. Fossils of alpine oak and felt oak that grew millions of years ago have been found at an altitude of 5,700 to 5,900 meters on the north face of Mount Everest.

    These plants still grow in many places in the south-west of the country at an altitude of 2,200 to 3,000 meters. Although the climatic conditions of a million years ago, the environment in which these plants grew and the height were not exactly the same as they are today, it can still be roughly estimated that the Himalayas have risen about 3,000 meters in millions of years, an average of about 30 meters per 10,000 years.

    It is not that the Himalayan region was an ocean, but according to geological studies, the Himalayan region was once an ocean.

    A large number of fossils of ancient marine life have been found in the Himalayan region, proving that it was once a sea. It was crustal movements and tectonic plate drifts that turned the Himalayas into land and uplifted into what is now the highest mountain range in the world.

    According to the "continental drift theory", the layers of rock on the earth's surface are not a single piece, but are divided into several large pieces, called plates. These plates are like "rafts" suspended over the mantle asthenosphere, drifting with changes in the mantle asthenosphere. Eurasia is a tectonic plate, as is the South Asian subcontinent, dominated by India.

    More than 200 million years ago, the Himalayas were an ocean, and the South Asian subcontinent was far away in what is now Africa. Since then, the South Asian subcontinental plate has separated from the African plate and drifted rapidly northeastward, colliding with the Eurasian plate 60 million years ago. The ancient Himalayan sea, between these two tectonic plates, was squeezed and violently uplifted, turning the sea into land.

    In geological history, this intense orogeny of the earth's crust is called the Himalayan movement.

    The Himalayas were not high at the beginning of their formation, but because the power of these two plates was too strong, it took more than 60 million years for the Himalayas to rise to a height of 3,500 meters, and in the last 100,000 years, the geological movement has become more and more intense, and the Himalayas have instantly increased by more than 2,000 meters. The world's highest peak has reached more than 8,000 meters and is still rising.

    The Himalayas have been lifted from below sea level by the combined action of the Eurasian and Indian Ocean plates, and are still growing taller

    Now the geological department has found a large number of fossils of marine life in the Himalayas, which proves the scientists' speculation about the movement of the earth's crustal plates.

    The Himalayas were formed by the collision of the Indian and Eurasian tectonic plates. The Indian Plate was originally made up of the Indian continent and the ocean that surrounds it, and the Indian Plate gradually subducted below the Eurasian Plate due to its continuous movement towards the Eurasian Plate. Over time, the oceans became smaller and smaller, and eventually the Indian continent met the Eurasian continent, thus forming the Himalayas, so there are remnants of the lost ocean in the Himalayas.

    This is evidence found in strata.

    The stratigraphic sediments of each age will show the geological and climatic characteristics of the time, and scientists have found marine fish fossils in a certain group of strata, so it can be inferred that the corresponding period of the strata is the ocean.
