All of the following are examples of how geographical boundaries can limit cultural interaction except  rivers

Explanation:

Rivers have historically been the reason of a lot of cultural exchange and not barriers to it due to many reasons.

The primary reason is that there is more chance of civilizations and settlements to happen near a river because of its rich nutrient soil and ready supply of fresh water to drink.

The other is the human ability to cross the water easily making it easy for the people to navigate it and meet people across.

The third reason is that the navigation downstream is how civilizations have historically expanded territory.
