Norway comprises the western part of Scandinavia in Northern Europe. The rugged coastline, broken by huge fjords and thousands of islands, stretches over 2,500 km as the crow flies and over 83,000 km including the fjords and islands. Norway shares a 2,542 km land border with Sweden, Finland, and Russia to the east. To the west and south, Norway is bordered by the Norwegian Sea, the North Sea, and Skagerak. The Barents Sea washes on Norway’s northern coasts.

At 385,252 km² (including Jan Mayen, Svalbard), Norway is much of the country  dominated by mountainous or high terrain, with a great variety of natural features caused by prehistoric glaciers and varied topography. The most noticeable of these are the fjords: deep grooves cut into the land flooded by the sea following the end of the Ice Age. The longest is Sognefjorden. Norway also contains many glaciers and waterfalls.

The land is mostly made of hard granite and gneiss rock, but slate, sandstone and limestone are also common, and the lowest elevations have marine deposits. Due to the Gulf Stream and prevailing westerlies, Norway experiences warmer temperatures and more precipitation than expected at such northern latitudes, especially along the coast. The mainland experiences four distinct seasons, with colder winters and less precipitation inland. The northernmost part has a mostly maritime Subarctic climate, while Svalbard has an Arctic tundra climate.
