Answer to Question 1

A mountain range forms under the same geological conditions along its length. This means that the
same or nearly the same rock types are found along the range's length in the same or nearly the same
sequence. The processes that form mountain ranges tend to create somewhat linear elevated features.
So a mountain range that has been split, even if it has been separated by an ocean, is fairly easy to
recognize.



Answer to Question 2

The glaciations on the Gondwana continents could only have occurred if the continents were joined,
since the centers of the glaciers would have been in the ocean if they were not. Also, the continents,
such as South America and Africa, match like a jigsaw puzzle. Fossil plant and animals are separated
by oceans, when the organisms must have lived in adjacent regions when they were alive. Finally,
similar rock sequences and mountain ranges could be connected across oceans.
