No one has ever questioned the United Ancient Continent before the drift?

1620 Englishman FBacon raised the possibility that the Western Hemisphere was once connected to Europe and Africa. In 1668, the French Platsey argued that the Americas were not separate from the rest of the earth before the Flood.

By the end of the 19th century, the Austrian geologist Hughes, ENoting that the rock formations on the continents of the Southern Hemisphere were very homogeneous, they were fitted into a single continent, known as Gondwana. In 1912, Wegener formally proposed the theory of continental drift, which was demonstrated in his book The Origin of Land and Sea published in 1915.

The mechanism of drift could not be better explained, and it was opposed by geophysicists at the time. From the mid-50s to the 60s of the 20th century, with the development of paleomagnetism, science and astronautical observation, the once dormant theory of continental drift was reborn and laid the foundation for the development of plate tectonics. In fact, there is no need to care about the united ancient continents before the drift, the question is how did the oceans form?

Because if there is no ocean, where is the theory of continental drift? In the early days, there was no water on the earth, and naturally there would be no oceans, but how the oceans were formed is still a mystery.

Addendum: Sorry, I didn't make it clear, I mean if there is no water on the earth, how can you tell how many continents there are on the earth? Doesn't the whole earth look like a whole continent? Because of the presence of water, people will find the phenomenon of continental drift.

Humans are the experimental product of other higher organisms.

The Moon is a camouflaged spacecraft. Right.

It appeared during the period between the formation of the earth's crust and the end of the dinosaur era.

The seafloor spreading theory holds that the ridge is the birthplace of the new oceanic crust, and the rocks closer to the ridge are younger, farther and older, and are symmetrically distributed on both sides. Mantle material emerges from the top of the ridge and condenses coldly, forming a new oceanic crust. Go on.

Rising magma pushes the old oceanic crust to both sides, when the oceanic crust that is pushed farther and farther meets the continental crust.

It subducts into the mantle beneath the continental crust, where it gradually melts and dies, allowing the seafloor to renew and expand.

Sheet. The theory of plate tectonics holds that the Earth's lithosphere is not a whole, but can be divided into six plates: the Eurasian plate, the African plate, and the Americas.

Plates, Pacific Plates, Indian Ocean Plates, Antarctic Plates. The theory of seafloor expansion is a theory of the growth and movement expansion of the seafloor crust, which is a further development of the theory of continental drift. It was proposed in the 60s of the 20th century by the American scientists H. H. Hess and R. S. Dietz respectively.

Plate tectonics (also known as global tectonics): This theory was proposed by the French scientist Lebison in 1968. The theory of plate tectonics is based on the theory of continental drift and seafloor expansion, and is based on a large number of marine geology, geophysics, seabed geomorphology and other data, and is put forward after comprehensive analysis.

In 1910, Wegener, a German meteorologist who was sick and bedridden, looked intently at a map of the world on the wall. He suddenly discovered that the topography on both sides of the Atlantic, especially between the east coast of South America and the west coast of Africa, corresponded to each other, and he proposed the theory of continental drift in 1912 by consulting various sources. The theory of continental drift holds that 250 million years ago, the continents that are currently divided into continents were connected, and there were no oceans at that time, and later, the complete pan-continents began to break up, gradually forming the current seven continents.

It was proposed in 1912 by the young German scientist Wegener. Through investigation and research, he found evidence of the similarity and continuity of paleontological fossils, stratigraphic structures, and lithofacies on both sides of the Atlantic. About 200 million years ago, due to the long-term action of the centrifugal force generated by the Earth's rotation and the gravitational force of celestial bodies.

Cracks began to appear in this joint ancient continent, and gradually separated and drifted. The lighter silicon-aluminum layer of land, like ice floating on the surface of the water, drifts on the heavier silicon-magnesium layer, and gradually forms the distribution of sea and land that people see today after a long geological time.

It won't be until hundreds of years from now!

It has been moving, but it is very slow, it is not felt, and there is no fast movement, because there is no power support, and it is believed that a strong volcano** is more likely.

The Himalayas were an ocean n years ago, and the two continents approached each other at about 2cm per year, and then slowly got higher and higher, and finally formed the Himalayas, which will take hundreds of millions of years.

The theory of continental drift is only a hypothesis and has not yet been conclusive. Even if it's true, it will take that long to drift back, so don't worry, there are still hundreds of millions of years left!

It will take at least 60 years to drift back.

Whether the drift theory is entirely correct is still being questioned.

[Plate theory, continental drift is an out-and-out shocking **].

The formation of land by the sedimentation of water completely negates the continental drift, the formation of new land is related to the sedimentation of water areas into new land, the formation of water by land is also related to water, water covers a large area of land, and land becomes water, which is the transformation of water and land, and continental drift has nothing to do with it, the change and redistribution of land and water in the landform is related to water, in the final analysis, it is the action of water that changes the distribution structure of land and water on the earth, and the emergence of new land is the water retreating, the land is gone, it is the water covering, It's not land drifting.

If the continents are drifting and the plates are moving, for the Himalayas, under the huge force of plate movement, the Himalayas will also move on a large scale, but all the geological textbooks, materials, and data do not have a little bit of information, and the Himalayas ** drift? Like which direction to drift? How far has it drifted? In the process of drifting, is there a landslide?

Again, regarding the order of lakes and basins, the two disciplines give two answers.

Geography: first there are lakes, then there are basins. Objective facts and experiments lead to the conclusion of geology: first there are basins, then there are lakes, which is based on the theory of plates.

In order to lie the "plate theory", structural geology has fabricated various types of basin formation, but however, there is only one kind of basin formation, that is, there is sedimentation in lakes and waters, as long as there is a sedimentation rate, the bottom of lakes and waters will rise over time, and eventually form marshland, land, and then transform into basins. This sentence is the key ***

Such a ridiculous answer came as no one expected. Errors in basic cognition will inevitably involve the correctness of various theories that follow. Well, the occurrence of this blind spot is extremely serious.

Next, the uplift and subsidence of the earth's crust can only form negative topography, not basins, uplift and subsidence can not form a sedimentary structure, and the sedimentary layer is a process formed over hundreds of thousands of years, and the uplift and subsidence of the earth's crust cannot complete the sedimentary process.

In addition, there are a large number of fish fossils, turtles and turtle egg fossils in the basin, then, before the formation of the basin must belong to the waters, otherwise, there will not be a large number of fish fossils, from the above aspects, it is concluded that the basin before the formation, is the water, not the crust is too subsidence can be completed, the cognition of structural geology is completely wrong, and it is also contrary to the view of geography.

Coupled with a strong evidence, there is a huge "gap" in the basic knowledge of all geology at home and abroad, that is, what kind of connection and transformation relationship exist between lakes and basins? It is quite dangerous and serious for a discipline to have a "gap" in knowledge that has ever existed.

The errors of structural geology caused the continental drift to be untenable, and the plate theory was not valid.

Focus: There is a huge "gap" in the basic knowledge of all geology at home and abroad, that is, what kind of relationship and transformation relationship exist between lakes and basins? It is quite dangerous and serious for a discipline to have a historical "blind spot" in knowledge.

Answering the cross-strait tectonics: North America, Africa, and Europe echo each other in stratigraphy, rocks, and tectonics. For example, the folded mountain system in Newfoundland in North America corresponds to the folded mountain system in Scandinavia in northwest Europe, both of which belong to the Early Paleozoic orogenic belt, and the southern tip of Africa and the southern part of Argentina in South America have the same Late Paleozoic tectonic direction, and the rock sequence is consistent with the fossils contained.

"Continental drift said" That's how it came about, let's explore it together.

Here's the evidence

Evidence 1 – Example of Indian plate drift. The Indian plate is a large plate that is moving rapidly from south to north.

Evidence 2 – Example of the New Caledonian Drift. New Caledonia, located northwest of Australia, is a long island, a typical island drifting in the ocean.

Evidence 3 – An example of a batfish-like mass located in the Northwest Siberian region that gave rise to the Hawaiian Island Chain.

Evidence 4 – Examples such as Madagascar and Iceland. Madagascar, located in the eastern part of the South African Plate, is a large land mass.

Proposer of the Continental Drift Doctrine:

The theory of continental drift was proposed by Alfred Wegener (1880-1930) in an important academic article in 1912.

It was developed and refined in a monograph published a few years later (1915).

The potentially revolutionary nature of this hypothesis was almost immediately recognized, as it required a revision of the entire foundations of geography.

In the 20s and 30s of the twentieth century, geographers discussed the idea of continental movement extensively, and as a result, the opposition was almost unanimous. Thus, Wegener's theory of earth drift was in what I call a theoretical revolution for a long time, and it was not until the mid-50s that new evidence was constantly discovered that became more and more favorable to the hypothesis of possible continental motion. But it wasn't until the 60s of this century (20th century) that a revolution in earth science really took place.
