Mainland Norway has a long, indented Atlantic coast backed by mountain terrain. In western Norway, fjords extend far inland and divide the coast into peninsulas and islands. The southeastern region around Oslo has a different mixture of lowland, forests, and settled valleys.
Fjords along a mountainous mainland
Trace Sognefjord from the coast into the mountains. Compare its branching outline with the less deeply cut coast around Oslo. This overview excludes Svalbard.

Glaciated coasts also occur in Chile and New Zealand. A single branching inlet cannot settle the country. Use several coastal features and their orientation, then compare the surrounding terrain.
