Asia or Europe so both

The first ocean the Caspian lost connection with was the Pacific Ocean.

Black Sea

The Volga River.

It goes to the Mediterranean Sea.

The Caspian Sea is mild in the north The Caspian Sea is warm in the south

Along the western and southern shores of the Caspian Sea, there are mountains (specifically the Caucasus, Alish, and Elburz Mountain Ranges going counterclockwise), but on the northern and eastern shores of the Caspian Sea, there are lowlands, some which are below sea-level.

the highest temp in caspian sea is 65 degrees

The Caspian sea does not have connection to the World Ocean, so it is not real sea (like Black sea, that ultimately connected to the Atlantic ocean via the Mediterranen sea).

The Caspian Sea is linked by canals to the Black Sea and via the Volga River and canals to the Baltic.

No. The South China Sea covers an area of 3,500,000 square kilometres (1,350,000 sq mi), while the Mediterranean Sea covers an area of 2.5 million km² (965,000 sq mi). So the South China Sea is the bigger.

The Caspian Sea is located in northwest Asia, landlocked between Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan. Since the breakup of the Soviet Union in 1991, the Caspian Sea well as the region surrounding has became the focus of much international attention due to its huge oil and natural gas reserves. The Sea, which is 700 miles long, contains six separate hydrocarbon basins, although most of its oil and natural gas reserves have not been developed yet. Although the littoral states of the Caspian Sea already are major energy producers, many areas of the Sea and the surrounding area remain unexplored.

The world's largest lake is the Caspian Sea at 371,000 sq km which is completely enclosed by Russia, Iran, Kazakhstan, Turkmenistan and Azerbaijan. The Caspian Sea is completely land locked and is 28 metres below sea level. The Romans thought it was a sea rather than a lake due to its huge size and the fact that the water was slightly salty to taste.

The Caspian Sea lies on the borders of Europe and Asia

Lake Superior is on the North American continent, Canada to the north, the US to the south.

Lake Victoria is located on the African continent, surrounded by Kenya, Uganda and Tanzania

Caspian Sea - Western Europe, Eastern Asia Lake Superior - North America Lake Victoria - Africa

Principally it's the Volga, there are many others.

This is just one of the most important ones :)

The only Middle Eastern country is Iran.

The countries that border the Caspian Sea are Russia, Kazakhstan, Turkmenistan, Azerbaijan, and Iran.

There is no such thing as the "Chadian Sea".

The Elburz mountain range is directly south of the Caspian Sea.

Aral Sea

Yes. Iran is the only country that borders both the Caspian Sea and the Persian Gulf.
