Why did most scientists of the 1920’s reject
Wegener’s theory?
1.
2.
3.
4.
The concentration of
continents in the Northern
Hemisphere
Lack of a mechanism for
continents to plow through
oceanic crust
The Earth was thought to be
too young for such
movements
Wegener was not a geologist
by training and so his ideas
were ignored
