Слайд 3 “Sacred sea”, “sacred lake”, “sacred water”

– these names have been given to Lake Baikal

since time immemorial by the indigenous population, by Russians who came to these shores in the 17th century, and by foreign travelers in their admiration for its beauty.

But is it really a lake ? Or, may be, it is a sea? We shall try to answer this question.

Слайд 5 The Baikal as a lake:
It may

be called a lake because its water is fresh

and it is surrounded by a land.
So, as a lake, the Baikal is the world's deepest lake. The water in it is so clear that if you look down you can count the stones on the bottom (through 60 metres of water!).
It is the same type of lake as Tanganyika in Africa.

Слайд 6 It is much smaller than the

Baltic Sea, but there is much more water in

it than in the Baltic Sea. Its depth – the depth of a sea or even
an ocean!

The Baikal as a sea:

The Baikal has not only separate islands (Olkhon is the biggest of them) but also some “archipelagoes” (Ushkanyi Islands, for example).

Слайд 7 The kind of storm, known as

the sarma, can tear the roofs off the houses

in the shoreline villages, to overturn launches and to throw sheep down the cliffs into the roaring waters. The sarma reaches a speed of forty or more metres a second.

The Baikal, as a sea, has different kinds of winds – almost from every river’s valley. The most famous of them are called after the rivers – the barguzin, the sarma, the kultuk.

Слайд 8 As a

sea, the Baikal has a great variety of

living creatures. It hosts 1,085 species of plants and 1,550 species and varieties of animals.

More than 80% of the animals are endemic.
Among them there are such animals (usually known in seas) as sponges (the Baikal sponge), seals (Nerpa), crustaceans (the Baikal epishura) etc.
