Due to the fact that many of the lakes, which now exist in nature, erroneously referred to as the seas, people often confuse these two terms.In order to be able to accurately attributed to one of the categories a particular body of water, you need to know what the lake is different from the sea with the scientific, geographical and geological point of view.So now we look at the main features of both, and then compare them.
Brief definition
lake So the lake is called a closed land on all sides of education is a deep trough.It is filled with water and is not related to any other planet's reservoirs (rivers, seas, glaciers, etc.).Lake relate to internal waters, which may have different origins and characteristics.For example, the largest lake is Caspian (often called the sea), filled with salt water.The deepest reservoir of the world is Lake Baikal - fresh-water sources in the area of the cleanest air.
Tectonic lake
To understand how different the lake from the sea, it is important to know the history of the origin of the water body.We will consider them on a visual example to compare.Break tectonic plate or strain - a recipe for deepening the appearance that can be filled with water.It was during these tectonic changes formed the well-known Baikal and the Caspian Sea.For a number of tectonic lakes can be attributed to the Aral Sea, which today is almost completely dried up.Some, like a lake traced on every continent.In Africa, the gap tectonic plates gave rise to ponds named Edward, Albert, Malawi and others.On the territory of Israel, is also located the giant tectonic salty lake - the Dead Sea.
Lake mountainous areas
easier to understand than the lake is different from the sea, it is possible, considering this body of water in mountainous regions.In these regions, the so-called popular dammed lakes formed by landslides of rocks and large stones.Thus the path of rivers and other bodies of water waste in the valley stops and forms a closed blind lake.Find these wonders can be in every area of the mountain ranges.They are there in Canada and in the United States and Russia, and the greatest number of them are concentrated in Asia, between multiple elevations.This topic also note that there are restricted bathing lakes, which are located in the craters of volcanoes.They have unearthly beauty, but the water contains a lot of gases and acids.
Determination sea
to completely comprehend what the lake is characterized by the sea, look at the second encoding.Sea - a part of one of the planet's oceans.It can only be salt water, it is directly connected to the "fatherly" big waters.It separates the sea from the ocean islands that rise above the level of his or underwater ridges.The sea can be different from ocean currents, flora and fauna, as well as climate.Seas are divided into internal and external.First tightly clamped mainland, have access to the ocean just across the strait.This is the Sea of Azov, the Black Sea, the Mediterranean Sea.The second is located on the map as one of the bays of the ocean, surrounded by islands.It Okhotsk, the Caribbean, the Andaman.
summarize
So the main difference between the lake from the sea is that the first belongs to the waters of the land, the second - the waters of the oceans.You can also note that in the seas we find extremely salty water of the lake can also be as a source of fresh and saline.Well, another difference is the number.Today there are 63 sea on the planet, but as there are the lakes - is still unknown.
