Question

Which of the following is a river in Europe?
a. Thames
b. Rhine
c. Danube
d. All of these

Answer 1

Hint:
 Europe is situated entirely in the Northern Hemisphere and partly in the Eastern Hemisphere as a continent. Europe occupies about 10,180,000 square kilometres, or 2% of the surface of the Planet, making it the second-smallest continent.

Complete solution:
 Europe is a vast region, with many major rivers linking its many nations. In Europe, there are five major rivers: the Danube, the Thames, the Volga, the Loire, the Rhine and the Elbe.
The River Thames, otherwise referred to as the River Isis in parts, is a river that runs through London and southern England. At 215 miles, it is the longest river in England and after the Severn River, the second-longest in the United Kingdom. The Thames drains Greater London as a whole.

After the Volga, the Danube is Europe's second-longest river. It is situated in Eastern and Central Europe. The Danube was once the Roman Empire's long-standing border and flows through 10 countries today. The river flows across the world's largest number of countries. Originating in Germany, the Danube flows southeast before draining into the Black Sea. Its drainage basin extends into nine more countries.

The Rhine is one of the main European rivers, which has its origins in Switzerland and flows through Germany and the Netherlands in a more northerly direction, emptying into the North Sea. It flows through the German Rhineland and the Netherlands and finally empties into the North Sea.

Hence, the correct answer is option D.

Note:
Europe lies mostly in the temperate climate zones, where dominant westerlies are exposed to them. Owing to the influence of the Gulf Stream, the atmosphere is milder relative to other regions of the same latitude across the globe.
