List The Countries With The Longest Coastline In The World
Three in four of the world are covered with waters and 97% of all the waters in the world are composed of sea and oceans. How much information do we have about the coasts, or the longest coastline country, sea, sand, sunshine, or the country with the largest coastline in the world? How many coastlines are there in total?
This page discusses the top 10 countries with the longest coastline in the world and the longest coastline in the world. Also, we will go through the interesting facts on coastlines and on the longest coastline country as well.
Below, you will find the longest coastlines in the world stated in sequential order:

Now, we will go through the amazing facts and information on the longest coastlines in the world.
Coastlines in the World - Facts and Information
Below, you will find the latest facts and information about the coastlines in the world:
Did you know that the total length of land where the coastline meets water is estimated to be around 502,000km (312,000 miles) of coastline around the world?
Coasts have various features, like caves, cliffs, beaches, and mudflats. Tides, waves, and water flow shape the land to form these coastal features.
The list of popular coastlines is as follows:
Do you know that there is no clear definition for coastline is adopted yet, as we generally consider it the synonym of shorelines; that’s why we distinguish it from the term shoreline in the following criteria:
Giving a representative estimate of patterns in coastal erosion or coastal accretion, or
The precision with which the area of the coastline not really settled;
Strength (repeatability) of the relating measuring technique (for example not impacted by tide or wave run-up);
The work needed to decide the coastline position;
Deciding if mediation is important if the coastline retreats (considering account assets and interests at stake).
There is a list of the most astonishing coastlines in the world, which is as follows:
Halong Bay, Vietnam
Rio de Janeiro, Brazil
Lofoten Islands, Norway
Great Ocean Road, Australia
Big Sur, California, USA
Legzira Beach, Morocco
Sub-Antarctic South Georgia Island
Cinque Terre, Italy
Na Pali Coast State Wilderness Park, Hawaii
Cape Town, South Africa
Skeleton Coast National Park, Namibia
Antrim Coast, Northern Ireland
We consider the coast as a point where the ocean meets the land. The 193,000 miles of coast around the world keep on varying continuously. The wind and waves lead to coast erosion causing the reshaping of the shoreline and cliffs and arches as well. Sediment also deposits along the coasts helping to reform the coastlines.
Do you know that coastlines are never straight? So, how does it happen?
Well! When waves move ahead, they drag the particles back and forth, thereby rubbing the bedrock along the coast and each other, slowly wearing pebbles into sand. This type of motion happens under the effect of high wave energy, thus leading to an irregular coastline.
FAQs on Countries With the Longest Coastline
1. What Is A Coastline In Geography?
A coastline is a line where land meets water is continuously changing and reshaping. It is a narrow strip of land that borders the sea along an island or a continent. It is an ideal place to see an invariantly changing landscape. Generally, we consider shoreline the synonym of coastline, but it is more preferable to define the shoreline as the physical transition between land and water, while the coastline is a proxy of the shoreline position that represents the boundary between land and sea for use in shoreline management.
2. How are coastlines formed?
Coastlines are formed with the help of the three following things:
Waves, Tides, and Water currents, So, when waves crash onto the shore, they become sporadic and erode the land. However, moving forward, they leave behind little parts of the sea, like shells, sand dollars, seaweeds, and hermit crabs, etc. The way coasts are shaped relies upon a lot on what type of components/materials are there in the land and water.
