What does this evidence suggest about the geologic history of the two mountain ranges?

Question

The mountain ranges were shaped by the same glacial movement.
Both mountain ranges formed simultaneously from separate volcanic eruptions.
The climate and weather conditions of the regions have remained identical over millions of years.
The two mountain ranges were once connected and part of a larger landmass that later split apart.

Answer 1

The evidence suggests that the two mountain ranges were once connected and part of a larger landmass that later split apart. This explanation is consistent with geological principles such as plate tectonics and the concept of continental drift, which indicate that landmasses can separate over time. If there are similarities in rock types, fossil records, or geological features between the two ranges, it would support the idea of a shared history before their separation.
