It has massive waves, salty water and depths exceeding 3,000 feet 🤯 But despite its name, the Caspian Sea is geographically classified as a lake because it has no natural connection to the ocean. Unlike the Black Sea, which connects to the Atlantic Ocean through the Mediterranean Sea and the Strait of Gibraltar, the Caspian Sea is completely landlocked. 🌍 But why is its water salty? Millions of years ago, the Caspian was part of a much larger body of water called the Paratethys. As land rose and water levels changed, this ancient sea split into separate basins, leaving salt behind. Rivers continue to bring more salt into the lake 🧂 To ancient people, this enormous body of salty water looked like a sea, which is why we still call it the Caspian Sea today. #caspiansea #caspianlake #largestlake #landlockedsea #atlanticocean #lakes #seas #learn #maps #learning #history #geography Sun, 18 Oct 2026 02:29:11 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://tube.blueben.net https://tube.blueben.net/client/assets/images/icons/icon-96x96.png https://tube.blueben.net/videos/watch/75a92905-accf-40e0-b5a6-5217228d29c8 All rights reserved, unless otherwise specified in the terms specified at https://tube.blueben.net/about and potential licenses granted by each content's rightholder.
