Qual foi o motivo pelo qual a hipótese de Wegener foi rejeitada?
Porque os cientistas da época já tinham provado que os continentes eram fixos.
Porque não havia um registo fóssil suficientemente extenso para sustentar a hipótese de Wegener.
Porque Wegener não conseguiu explicar, de forma plausível, quais eram os mecanismos responsáveis pelo movimento dos continentes.
Porque Wegener não apresentou nenhuma evidência para fundamentar a sua hipótese.
Porque é que a hipótese de Wegener é considerada importante, apesar de ter sido rejeitada?
Porque Wegener provou que o movimento dos continentes ocorre devido à
força de rotação da Terra e à atração do Sol e da Lua.
Porque Wegener provou que os continentes nunca mudaram de posição.
Porque Wegener era um geólogo reconhecido na comunidade científica.
Porque contribuiu para o desenvolvimento de teorias posteriores na área da Geologia.

What happens at a transform boundary?
the plates move away from each other, creating a mid ocean ridge
they aren't dense enough to subduct, so they fold into each other, creating a mountain range
the oceanic plate subducts underneath the continental plate because it is much denser, creating an ocean trench and a volcanic arc
the plates slide past each other, creating a fault line and causing earth quakes

the plates move away from each other, creating a rift valley
