Baltic Sea

The Conclave of Kaliningrad, also St Petersburg may be included

Between January and March covering an area of 218,000 square kilometers

Sweden, Finland. Russia, Germany. Estonia, Latvia, Lithuania, Poland and Denmark

It is about 1,325 miles away

The country that is south of Latvia and has a coastline on the Baltic Sea is Lithuania. Its capital is Vilnius.

Kiel

There are several notable port cities in Germany that are on or near the Baltic Sea, but Kiel is the largest and most profitable.

People do; there are several beach resorts on the North Sea coast in the UK - but it is cold!

Russia's entire northern coastline is on the Arctic Ocean. Russia's eastern coastline is on the Pacific ocean mostly comprising the Bering Sea, the Sea of Okhotsk and the Sea of Japan.

There is also access to the Baltic Sea via the Gulf of Finland at St. Petersburg, and access to the Baltic Sea at Kaliningrad, a small Russian enclave surrounded by Lithuania and Poland.

There are over 60 rivers that empty into the Baltic Sea, The German river Trave near Lubeck - In Poland, the Vistula, - In Lithuania the Neman. - In Latvia the Venta River, - In Estonia The Pirita, - In Russia the Neva, - In Sweden The Tommarpaan. There are many others

The Baltic Sea has a very complex system of replenishing itself. It discharges around 940km3 of brackish seawater into the North Sea, while a subsurface layer of more saline water flow brings back 475km3 , this happens because of the different salinity levels.
The deeper you go in the Baltic Sea, the more saltier the water is.
The shortfall is made up of fresh water from over 250 rivers and streams that discharge into the sea, including the rivers Oder and Vistula.

The Eastern Front stretched from the Baltic sea to the Black sea in WWI.

There are three countries in the region known as the Baltic States. They are Estonia, Latvia, and Lithuania. However, the Baltic Sea borders many more countries, such as Finland, Russia, Sweden and Poland.

The Black Sea is located between Asia Minor and southeastern Europe and has many port cities that include Istanbul, Constanta, Odessa, and Varna. Istanbul is a port city in Turkey on the Black Sea.

The the North Sea and Baltic Sea are separated by:

The Danish Straits (Great Belt, Little Belt, Oresund)

Kattegat

Skagerrak

I don't know? Possibly because the Dead Sea has no openings, and anything that goes in it, stays there. While the Baltic Sea has openings and water flows in an out of it giving it less salt because the salt flows out.

Simple, i think...Also, the Baltic Sea is much bigger than the Dead Sea. Maybe that's why aswell...

It is the Danube canal.

The Danube crosses Europe, but not connecting the Baltic to the North Sea, the answer is the Kiel Canal

This is a hard answer to pin down, because no-one really knows. So this answer is really speculation.

The first person to name it as the Baltic Sea (Mare Balticum) was the 11th century German chronicler Adam of Bremen.
Some claim it might be connected to the Germanic word belt, a name used for two of the Danish straits, the Belts, while others claim it to be derived from Latin balteus (belt). While others believe that it is derived from the Danish baelte, which also means belt.
All we know for certain is that Adam of Bremen describe it as 'Balticus, eo quod in modum baltei longo tractu per Scithicas regiones tendatur usque in Greciam', roughly translates as ' it stretches through the land as a belt.'

Finland, Estonia, Latvia, and Lithuania.

The last three are collectively known as the Baltic States.

(Poland, farther west, has also been occupied or controlled by Russia in the past. Belarus, farther east, was the Byelorussian Soviet Socialist Republic in the USSR.)
