In what ways has poland suffered because of its lack of natural barriers

The correct answer for: In what ways has poland suffered because of its lack of natural barriers Is: Invasions, conquests and natural disasters.

Explanation:

First of all, we need to understand why some countries in eastern Europe are called the Iron curtain while Poland is not included in them. Normally, rivers, mountains, and desserts have been natural barriers or frontiers for humans and floods. However, Poland's terrain is highly open. It does have rivers, but they are not as big as many other countries' rivers. And even though it has a certain acceptable number of mountains in the south the west and east are open, as well as its coast with are majority made of beaches. This has turned Poland over the years to a passage over west and east. Invasions and armies have crossed over it hundreds of times.
