Sensible boundaries for dividing continents? Do the Rocky Mountains count as dividing North America into east and west subcontinents? Does the Baltic Sea partition the Nordic countries into their own continent? Are you really expecting that logic to work even a little bit?

The east part would be a bit small, but after a bit more seismic activity that may be sensible.

Could be a subcontinent border yeah, it is a common division in Europe.

Yeah, there are multiple aspects of continents and topology is one part. Others are cultural and political and I think there the division is even more clear.
