From Quiz Peggy Louisa Visits: Moscow
Answer:
Moscow
No, I didn't invent the Moscow (Moskva in Russian) River to trick you! It is actually the city's main river, although one of its tributaries, the River Yauza, also runs through the north east part of the city. The Moscow River is a tributary of the Oka River (which is in turn a tributary of the Volga) and is 503km (312 miles) long.
The Volga is the best known of Russia's rivers and is actually Europe's longest river at nearly 3,700km (2,300 miles). It empties into the Caspian Sea.
The Neva is St Petersburg's river and the Don is another of Russia's main rivers. At nearly 2,000km (1,200miles) in length, it rises to the south east of Moscow and empties into the Sea of Azov.
