Norway The Gulf Stream has this effect only on the northern parts of Norway, not in the south, despite what is commonly believed. The northern coast of Norway would thus be ice-covered if not for the Gulf Stream. As a side-effect, the Scandinavian Mountains prevent continental winds from reaching the coastline, causing very cool summers throughout Atlantic Norway. Oslo has more of a continental climate, similar to Sweden's. The mountain ranges have subarctic and tundra climates. There is also very high rainfall in areas exposed to the Atlantic, such as Bergen. Oslo, in comparison, is dry, being in a rain shadow.
Geology of Norway is interpreted to be a precursor to the break-up of the North Atlantic. Little is known of the then elevation of what would be the area of current day Norway. Geology of Norway The geology of Norway encompasses the history of earth that can be interpreted by rock types found in Norway, and the associated sedimentological history of soils and rock types. The Norwegian mountains were formed around 400 million years ago (Ma) during the Caledonian orogeny. Rocks of Archean age in Norway are confined to a few 10 km-scale areas within younger metamorphic belts exposed on islands off the
