What term is given to the border between the Central Alps and the Southern Limestone Alps?




Periadriatic Seam.

 The border between the Central Alps and the Southern Limestone Alps is the Periadriatic Seam.
The Periadriatic Seam (or fault) is a distinct geologic fault in Southern Europe, running S-shaped about 1000 km from the Tyrrhenian Sea through the whole Southern Alps as far as Hungary. It forms the division between the Adriatic plate and the European plate. The term Insubric line is sometimes used to address the whole Periadriatic Seam, but it is more commonly used to mean just a western part of it




Hint:

In sewing, a seam is the join where two or more layers of fabric, leather, or other materials are held together with stitches. Prior to the invention of the sewing machine, all sewing was done by hand.
