The correct answer is the Adriatic Sea- it's more to the north than Greece and it ends around Albania, which borders Greece to the North,

The answer is "Delta"
Delta is a flat triangular shaped land formed when a river carries and deposits
sediment at its mouth.
This usually happens where a river is entering an ocean, sea,
lake, reservoir,
and another river that cannot carry away the sediment supplied by the river.
The last one happens very rarely (Entering a river).
