The largest lake on Earth… What is it? Agree that the word “lake” seems a quiet and peaceful pond, overgrown with reeds. In it, closing her eyes, we see white water-lilies, and to the other side just the same hand.
However, few people think about the fact that there are such lakes, which will give odds to some of the seas, both in size and depth and strength of storms occur periodically.
Today I propose to talk about them.
The largest lake on Earth. Its characteristic features
Oddly enough, but the largest lake on Earth we used to call the sea, or the Caspian sea. In fact, taking into account its features, call it the sea is simply impossible. Why? Yes, because according to the definition, the last should fall any river, but located at the crossroads of Europe and Asia the Caspian sea is endorheic.
If you look closely at pictures taken from space, you can immediately note one undeniably important feature. – the Caspian sea has a rather complex shape resembling the letter S from the Latin alphabet.
Its dimensions are really impressive: the length from North to South is approximately 1,200 km, but the distance from the East to the West coast differs Continue reading
Sometimes it happens that we colloquially confuse “sea” and “lake”, meanwhile you can find a number of fundamental differences.
Sea – into the land or isolated shores of the mainland, the rapids or the Islands of the ocean. Sea there are internal (inland), marginal, and inter-island imaterialise.
Internal – this is the sea, located on the land surface. As a rule, they communicate with the ocean by one or several Straits. These are the Black, Azov, Baltic sea. Marginal seas, unlike the mainland, adjacent to the mainland or separated from the ocean by Islands, for example, the Chukchi and the Barents sea. Imaterialise sea located between the continents: Red and Mediterranean seas. Inter-island sea are usually located between the major Islands. This is the Java sea. It happens that the water basin is completely isolated from the World ocean, respectively, that lake, but it is called the sea because of the large size (Caspian sea).
Kilogram of seawater contains 35 grams of various salts: 27.2 grams of sodium chloride, 3.8 grams of magnesium chloride, 1.7 grams of magnesium sulfate and a little less grams of calcium sulfate.
Edible salt is produced by evaporation of sea water. The first precipitates salt because Continue reading
Volcanoes for many of the uninitiated seem to be something fantastic and inconceivably terrible. In order to get a better idea about these objects we quote the interesting facts about volcanoes.
Only volcanic stone floating on the water’s surface is volcanic pumice. It is characterized by grey color, this stone is riddled with hollow holes formed during the cooling of the stone. This process was accompanied by the release of gases that are formed holes.
volcanic pumice, Interesting facts about volcanoes
The eruption of huge volcanoes, supervolcanoes called, often cause dire consequences. It is fire and rain, shed for miles around the volcano itself, and global climate change caused by ingress of ash into the atmosphere. Fortunately, these volcanoes erupt on the average several times in 100,000 years. One of them, located on the territory of Yellowstone national Park, scientists say that, in all likelihood, ready for another eruption.
the eruption of a SUPERVOLCANO,
The largest of the observed eruptions is considered to be the activity of the volcano of Tambora on the Indonesian island of Sumbawa. The eruption killed 100,000 people. According to researchers in Indonesia is home to the largest number of historically active Continue reading
