How Wegener proved his conjecture

Wegener did not directly prove the theory of continental drift. At the time, no one agreed with his hypothesis.

It has been proved by later generations in practice, mainly including, paleontology, palegeology, paleomagnetism and modern patchwork technology.

It was discovered while playing puzzles while in the hospital.

Continental drift. When he was hospitalized, he was so idle that he went to map the world, and then discovered that several continents could be put together to form a pan-continent.

Continental drift theory is a hypothesis that explains the distribution and evolution of land and sea. It was systematically proposed in 1912 by the German scientist Wegener. Based on the analysis of evidence from coastal topography, paleogeology, paleontology and paleoclimate, he believes that before the Jurassic period (about 200 million years ago), there was only one unified continent on the earth, called pancontinent (or joint paleocontinent), surrounded by a pan-ocean.

Since the Jurassic, the pancontinents began to disintegrate and drift apart, gradually forming the current pattern of sea and land distribution.

Wegener's main evidence for continental drift is as follows: first, the similarity of the shapes of the two sides of the Atlantic, which, if spliced together, can become a whole, indicating that they were once connected in the past; Second, the Permian folded mountain system in South Africa and South America have the same trend and similar geology, indicating that they were once the same land mass. Third, there are traces of Late Paleozoic glaciers in South America, South Africa, South Australia and southern India, and only by combining them together can the distribution of glaciers be explained. Moreover, on these moraines, there are generally coal-bearing strata of fossils of tongue sheep's tooth plants. Proof that these distant continents were originally connected.

The theory of continental drift, which advocates the existence of large-scale horizontal movement of the earth's crust, is a challenge to the traditional fixed theory, has a positive significance for promoting the development of geological science, and lays the foundation for the rise of the theory of seafloor expansion and plate tectonics. However, Wegener's failure to solve the problem of the dynamics and mechanisms of continental drift became a weakness of the hypothesis, and it was depressed for a time.

It's the German meteorologist.

Answer: Wegener's discoveries and hypotheses suggest that he was a scientist (fond of fantasy and adventure**).

Wegener was a German meteorologist, geophysicist, astronomer, and the founder of the theory of continental drift. Born in Berlin on November 1, 1880, he was killed in November 1930 while visiting the Icefield in Greenland. Proposed in 1910"Continental drift said", confirmed in 1912.
