Because he didnt have enough "scientific" eviedence
Because wegner didnt have proof to show what caused mountains.
Many scientists dismissed the theory because it flew in the face of conventional wisdom.
Test your hypothesis against the data
A hypothesis can be supported by checking it against your research to see if it is true, checking it against research done by others, and testing your hypothesis rapidity.
Test your hypothesis against the available data
A statistical hypothesis is anything that can be tested against observations. So the hypothesis can be that you can remember two numbers.
A theory is a hypothesis which has been tested (against "reality").
An army established by the Continental Congress to fight against Great Britain.
The Himalayas and the Tibetan Plateau are formed by a continental-continental boundary where the Indian continental plate is moving north against the Eurasian continental plate.
I've included 3 links on Alfred Wegener's life. He died at the age of 50 in 1930. His speciality was meteorology and well published in this area. The concept of continental drift began by the observation of the close fit between South America and Africa. Fossil evidence gave some support to the hypothesis. The concept of the continents drifting for hundreds of millions of years was criticized as too radical a departure and based on scant evidence. Also, in Wegener's hypothesis was the existence of Pangaea, where initially all continents were connected. George Gaylord Simpson was a well known scientist who was highly critical of continental drift. The view to the contrary was the continents had remained fixed and it was the plants and animals that had dispersed themselves on both continents. Per George Gaylord Simpson, his paper in 1939 seem to lay a solid foundation against continental drift. Antarctica as a faunal migration route. Proceedings, Sixth Pacific Congress, 1939, p. 755-768. First of Simpson's papers that directly addresses historical biogeography. He argues that land-bridges and continental drift are not necessary to explain disjunctive distributions. "In scientific theory the best-supported and most nearly self-sufficient hypothesis should be preferred and unnecessary additional hypotheses should be rejected or held in abeyance." (See "Evolution and Geography," 1953.) It is recognized today that Alfred Wegener was way ahead of his time.
The Continental System called for an embargo against British trade.
