3.Climate.
Climate in Eurasia is very different, because the continent is very large and occupies all the climatic belts of the northern hemisphere. Winter is very cold in the north and hot in the south. The amount of rainfalls changes from 50 mm a year in central Asia to 5 000 mm a year at the foot of Himalayas.
The Arctic Polar Circle crosses the northern part of the continent; the southern part comes close to the equator. Large part of the continent lies in the temperate climatic belt, where western winds blow. Trade winds influence on the southern part of Eurasia and monsoons – on the eastern part of the continent.
The size of the continent also influences the climate of it. The coastal regions receive many rains from the oceans. The cold air masses from the Arctic Ocean spread far southward. The continental climate with cold winter and hot summer is in Central Asia. The Atlantic Ocean brings warm and wet air to the western part of the continent. On the shores of the Mediterranean Sea forms the Mediterranean climate.
Relief is among the chief factors influencing on the climate of Eurasia. The Alps, the Caucasus and the Himalayas block the way to the cold arctic air masses and to the warm and wet equatorial air masses.

4.Inland Waters.
Many large rivers are situated in Eurasia. They have their sources in the mountains and flow into the four oceans. The largest rivers of Russia flow into the Arctic Ocean. They are the Ob (5 410 km), the Irtysh (4 248 km), the Yenisei (4 102 km), the Angara (1 779 km) and the Lena (4 400km).
Almost all rivers in foreign Europe flow into the Atlantic Ocean. They rise in the mountains. They are the Seine (776 km), the Vistula (1 047 km), the Oder (854 km), the Elbe (1 165 km), the Danube (2 850 km), the Rhine (1 320 km), the Don (1 870 km), the Dnieper. The longest river here is the Danube. The second largest river is the Don.
The rivers of Eastern Asia empty their waters into the seas of the Pacific Ocean. They rise in the high mountains. They are: the Amur (4 440 km), the Hwang Ho (4 845 km), the Yangtze (5800 km). The rivers of the Indian Ocean basin are: the Indus (3 180 km), the Ganges (2 700 km), the Tigris (1 850 km), the Euphrates (3 065 km), the Mekong (4 500). They are rain-fed and snow-fed.
The Volga (3 531 km) is the longest river in Europe falls into the inner sea – the Caspian Sea, which is sometimes called the greatest salt lake.
There are some lakes in Eurasia. They are: Lake Baikal ( 1620 m deep) – the deepest lake in the world, Lake Geneva ( in the Alps; 310 m deep), Lake Balhash (26 m deep), Lake Issyk-Kul (668 m deep), Lake Onega (127 m deep), Lake Ladoga (230 m deep).
