whats a good statement of the wegeners theory?

Answer 1

It's not the wegener's theory. Wegener is a person:Alfred Wegener. He was the first person to publish the theory of Continental Drift that states that the Earth's continents had at one time been all connected in a supercontinent that he named Pangea and then had drifted apart. It was based on observations that the continents seemed to fit together like a puzzle if you pushed them back together and that similar fossils and plants were found on both sides of the Atlantic.

Wikipedia has a good summary too if you look under continental drift and/or Wegener

Answer 2

Continental drift was hotly debated off and on for decades following Wegener's death before it was largely dismissed as being eccentric, preposterous, and improbable. However, beginning in the 1950s, a wealth of new evidence emerged to revive the debate about Wegener's provocative ideas and their implications. In particular, four major scientific developments spurred the formulation of the plate-tectonics theory: (1) demonstration of the ruggedness and youth of the ocean floor; (2) confirmation of repeated reversals of the Earth magnetic field in the geologic past; (3) emergence of the seafloor-spreading hypothesis and associated recycling of oceanic crust; and (4) precise documentation that the world's earthquake and volcanic activity is concentrated along oceanic trenches and submarine mountain ranges.

Answer 3

Gator was right, but the main gest is not that part, as it is shared by other theory(ie, the seafloor spreading theory) but rather that continents moves on the ocean floor, which they don't according to the seafloor spreading theory(ie, the one we are using today)
