While Sweden and Finland have mountains, Norway is dominated by the Scandinavian Mountains, which stretch along the western border and include the highest peak in Scandinavia, Galdhøpiggen (2,469 meters).
Here's a quick comparison:
* Norway: Dominated by mountains, covering almost half the country.
* Sweden: Has a smaller mountain range in the north, known as the Scandinavian Mountains, but also has rolling hills and plains.
* Finland: Mostly flat with a few low-lying hills and a small mountain range in the north (Lapland).
