why is Norway’s coastline so long?

Norway’s coastline is incredibly long due to its unique geography, which is characterized by a vast number of fjords, islands, and peninsulas. Here are several factors that contribute to the length of Norway’s coastline:

  1. Fjords: Norway is known for its stunning fjords, which are deep, narrow inlets of the sea between cliffs or other steep sides. Fjords carve out long strips of coastline as they extend inland. The country has numerous fjords, and their combined length adds significantly to the total coastline.
  2. Islands: Norway has a high number of islands along its coast. These islands, many of which are mountainous and rugged, also add to the length of the coastline. The Norwegian coast is dotted with thousands of islands, and the numerous bays, coves, and inlets between them contribute additional mileage.
  3. Peninsulas: There are several large peninsulas along the Norwegian coast, which are extensions of land that protrude into the sea. These peninsulas, with their indented coastlines, further increase the overall length.
  4. Mountainous Terrain: Norway’s terrain is mountainous, with the mountains often running parallel to the coast. This results in a highly indented coastline as the mountains prevent the sea from advancing inland in a straight line.
  5. Rocky Shores and Cliffs: Much of the Norwegian coast is characterized by rocky shores and cliffs, which add to the coastline measurement as they are counted along their entire length, including any overhangs or sea stacks.

According to the Guinness Book of World Records, Norway has the longest coastline in the world, with a total length of approximately 195,000 kilometers (121,000 miles), when measured using the dog-leg method, which counts each individual indentation. If measured using the direct line method, the coastline would be shorter, at around 69,000 kilometers (43,000 miles). either way, the coastline of Norway is a remarkable feature of its topography, offering a stunning array of natural beauty and a significant contribution to its unique geography.
