The Longest Coastlines in Asia

A list of Asian countries by the length of their coastlines.

A coastline is a thin piece of land that neighbors the sea along a continent or island. It keeps deforming and reshaping, meaning that its features are always different. There are continents with some of the longest coastlines, for example, Asia which is among the largest continents worldwide. It covers about a third of earth’s mass of land and is located to the north of the equator. Isthmus of Suez gives Asia a connection to Africa, and along the Ural Mountains, it borders Europe. Asia has coastlines in the north, east, and in the south. The coastline in the north is at the Arctic Ocean and to the east is at the Pacific Ocean, and finally, the coastline in the south is at the Indian Ocean. Here are some of the longest coastlines in Asia.

Effects of the Coastlines

Asia has been proved to have the biggest number of countries with long coastlines. Such countries include Indonesia, Russia, Philippines, Japan, and China. Coastlines have formed some culture, and economic benefit from activities such as trading, fishing, and shipping take place around them. As much as this is good for business and tourists, countries that have long coastlines may be facing threats. For instance, sea levels are increasing leading to effects of global warming. If the water levels of the sea start rising, it will be dangerous to the cities being hosted by the mentioned countries and ignorance will lead to disastrous effects.
