The Caspian Sea is a inland sea locked and locate between Asia and e are many countries around it as Russia,Iran,Turkmenistan middle-asia surround the north&east of it.
裡海位於亞洲與歐洲之間，是一個被陸地封鎖了的內陸海。環繞裡海的國家有：俄羅斯 (達吉斯坦、卡爾梅亞, 阿斯特拉罕)、亞塞拜然、伊朗 (馬贊德蘭省)、土庫曼及哈薩克斯坦, 中亞大草原環繞著裡海北部和東部。
The Caspian Sea is one of the smallest sea in the the fact it is a sea and it's the largest inland body of water in the world and have a area of 371.000 .
裡海是世界上最小的海之一。實際上，根據科學家的定義，裡海同時具有海和湖的特徵。裡海是世界上最大的內陸水體。裡海面積371,000 平方公里 (143000 平方英里).
The Caspian holds a great amount of sturgeon, which yield eggs that are processed into caviar. Overfishing threatens the sturgeon population, to the point that environmentalists advocate banning sturgeon fishing completely until the population recovers.
裡海生產大量的鱘魚，這些鱘魚可以加工成魚子醬。因為過度的捕撈鱘魚威脅到這種魚類的數量，所以環保工作者們提倡禁止捕撈鱘魚直到鱘魚數量回升。
Potentially huge oil fields also lie underneath the Caspian Sea. The main problem is the status of the Caspian Sea and the establishment of the water boundaries between the five riparian countries. The level of the Caspian has fallen and risen many times over the centuries. Some Russian historians claim that a medieval rising of the Caspian caused the coastal towns of Khazaria, such as Atil, to flood. The Volga River and the Ural River discharge into the Caspian Sea.
在裡海的底部存在了巨大的石油能源。主要的問題就是裡海的位置和五個繞裡海國家的水分界線的劃分。在過去的時間裡海的水位不斷的增長和下降，一些俄羅斯的歷史學家提出了一箇中世紀的導致裡海水位增長的原因。伏爾加河以及烏拉爾河都有流入裡海。
一萬多年前，裡海曾與黑海、地中海相連，海水彼此溝通。後經地殼運動，地形發生了明顯的變化，高加索山和厄爾布林土山的崛起，把裡海與海洋分離開了，從而形成今日這個內陸湖。裡海是鹹水湖，平均鹽度為千分之11至13。
