What is the name of the sea in this image? I was reading in Wikipedia about the Indian Ocean and I saw there an image of the part of the globe with a "closed sea" (it's marked by a red arrow in the attached picture). What is the name of this sea?
That's the Caspian sea, considered the largest enclosed inland body of water on Earth by area. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the west, Iran to the south, and Turkmenistan to the southeast.
