Geography quiz: are you an expert on countries around the world?

Do you know which countries have the most islands and lakes? Are you unbeatable when it comes to the land borders of the different states? To find out, take our 100% geography quiz in pictures!

First of all, can you tell which state has the most border countries? Hint: it is a very big country.

Russia!

Russia shares a land border with no less than 14 countries: Norway, Finland, Estonia, Latvia, Belarus, and Ukraine on the European side, Georgia and Azerbaijan in the Caucasus, and Kazakhstan, Mongolia, China, and North Korea in Asia. Moreover, the enclave of Kaliningrad gives this country a common border with Poland and Lithuania.

And which country shares the longest land border with France? Spain, Italy? Germany? You are still not there.

Brazil!

The correct answer is Brazil, the giant of the South American continent which shares a 730-kilometer-long border with French Guiana.

Speaking of Brazil, you should also know which is the longest river in the world. There is some debate about whether it's the Nile or this one...

But we've sided with the Amazon in this debate.

Its length is estimated at more than 7,000 kilometers and it has given its name to the gigantic Amazon Forest, the lung of the world.

While some countries in the world are known for the length of their rivers, others are known for their lakes. Do you know which one has the most?

Canada!

Canada, the second largest state in the world after Russia, has as many lakes as the rest of the world combined. Geographers estimate that there are more than 30,000 lakes of at least 3 square kilometers in Canada.

But, by the way, do you know which is the largest lake in the world? Its name might mislead you…

The Caspian Sea!

Indeed, the Caspian Sea has long been considered a closed sea because its water is salty. But its lack of access to an ocean and the fact that its level is lower than that of the sea, have caused it to qualify as a lake. With 371,000 square kilometers, it's the largest in the world.

Which country has the most islands? Estimates vary from one source to another as it is difficult to measure an incredible number of islets, often very small and uninhabited.

Sweden!

According to Statista data cited by 'Sciencepost', the record is held by Sweden, with around 221,800 islands, followed by two other Scandinavian countries: Finland (188,000) and Norway (55,000).

Some countries like Indonesia or Japan are made up of huge archipelagos with many islands. However, one state consists mainly of the largest island in the world.

Australia!

Whether you consider it a continent on its own or a country, Australia is bordered completely by the ocean and measures 7,741,200 square kilometers.

The world is full of impressive caves. Do you know where the deepest cave is located?

Trick question: what is the largest country in Europe? Russia? No, because its territory is mainly in Asia. Ukraine, France, Germany, or Spain? Suspense...

Denmark!

It is actually Denmark because this state is sovereign over Greenland. With a total area of 2,210,000 square kilometers, the kingdom is the 12th largest state in the world.

Finally, can you say which is the only continent straddling the four hemispheres of the globe?

Africa!

Yep, that's Africa, which spans the northern, southern, eastern, and western hemispheres – even though most of the continent is north of the equator.

So, how many correct answers did you get out of 10?
