Menu and nodes

Hello,

If I have a menu like this:

-World
--Europe
---Germany
---Romania
---France
--America
---USA
---Canada

It is possible to have a site structure like this:

-World ---> node/world
--Europe ---> node/world/europe
---Germany ---> node/world/europe/germany
---Romania ---> node/world/europe/romania
---France ---> node/world/europe/france
--America ---> node/world/america
---USA ---> node/world/america/usa
---Canada ---> node/world/america/canada
?
(if your country isn't in your list, please don't be angry)

Thank you for your help!!
