Geography. Before the last ice age ended about 10,000 years ago, Norway was covered by a thick ice sheet. When that ice finally retreated (or melted) its movement across the land formed islands, lakes, rivers and mountains. It also etched-out deep valleys that then filled with sea water forming Norway's fjords. Norway is one of Europe's most mountainous countries, and dominated north to south by the many ranges of the Scandinavian Mountains.
The geography of Norway is dominated by vast mountain ranges broken up by valleys and fjords. Less than 10% of the country's area is arable, and the rest is mountainous. Glaciers are the major cause for erosion, so terrain in Norwegian mountains consists of plateaus and lakes with peaks.he treeline is also lower near the coast and higher on the eastern part of the mountains. Mountain ranges also form the main boundaries among Norway's districts. They typically run north-south.
