Asia-Africa: political: Egypt/Israel and Gaza/Egypt boundary.
Or for a nicer physical line, the suez canal which leaves Sinai in Asia.
Or seeing Sinai is so symmetric, a nice biscting line N-S down it.


N&S America.
Political <1903: Colombia-Costarica
>1903 Panama-Colombia

Physical line: Panama canal.

I like the Panama-Colombia line as it hasn't been crossed by a road (yet).

The crest of the Urals and caucuses make a nice phusical line for europe,
but we might want to put Armenia, if not Azerbaijan in Europe culturally.
Thus there are near-overlapping but not quite coincident definitions of the
continent: physical, cultural, linguistic, political, ecological etc.

Remember the Wallace line in Indonesia!
