Which evidence did wegener make use of to develop the theory of continental drift?

there is no evidence of glaciers anywhere in south america.

the rocky mountains are taller than the appalachian mountains.

mountains in north america appear to be part of the same chain of mountains as those in northern europe.

the climate of siberia has always been the same.

C they're on different continents but in pangaea they were together and the continents split apart due to plate tectonics - definitely continental drift

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
