A physical map of Europe is located in the link below. It seems that the most mountainous region of Europe is either Central Europe or Eastern Europe.
The second most mountainous country in Europe is Switzerland. It is known for its stunning Alps mountain range, which covers a significant portion of the country's landscape.
No, France is not the second most mountainous country in Europe. Countries like Norway, Switzerland, and Austria have higher average elevations and more prominent mountain ranges than France.
Norway
Most likely Portugal.
I'm not 100% percent sure but I'm pretty sure Spain is the 2nd most mountainous country in Europe
There are mountains in many countries in Europe, but Switzerland probably has the most.
The southern part of Eastern Europe, or Southeastern Europe, is the most mountainous part of Eastern Europe.
Germany has the most breweries on any European country and the second most in the world.
More people live in Russia than any other European country. The second most populated country in the continent of Europe is Germany.
Norway is the most mountainous Scandinavian country, with rugged terrain and numerous mountain ranges, including the Scandinavian Mountains and the Jotunheimen range.
Germany, after Russia, with 82,000,000. However Russia is not fully in Europe so Germany would be the most populated country fully in Europe, meaning France, 65,000,000, would be the second most populated country wholly in Europe. (not counting its territorial population.)
In the USA, there are several mountainous areas. For example, Nevada is known as the most mountainous state. In second place is the state of Alaska.
