Question

Which theory suggested that the earth was once a single “supercontinent” that gradually broke up into the continents that we know today?

Answer 1

When you put the continents next to each other (on a map, of course) in a certain way, they put together almost perfectly. To add to that, there are fossils of the same land species on two different continents, suggesting that they used to be able to cross back and forth between the two land masses. This would make the most sense if the two continents were once part of the same continent.

Answer 2

A. continental drift theory

B. plate tectonics

C. subduction

D. seafloor spreading
