Caucasus is a Mountain range between Europe and Asia , between the Black Sea and the Caspian Sea. The range consists of two smaller ranges: the Greater-Caucasus, which includes Elbrus, the highest mountain of Europe, and Lesser-Caucasus, which lies to the south.
The Greater-Caucasus range is the dividing line between Russia and countries of Georgia and Azerbaijan. The Lesser-Caucasus extends from the south part of Georgia, through Armenia, to the southwestern section of Azerbaijan. This smaller range is adjacent to Turkey and Iran as well.
