There are some small islands in the Pacific Ocean, why do those islands have the names of countries

No one is independent! Just belonging! Not a colony!

It shows that it is still a British colony and has not yet become independent! Become an independent state.

Probably a colony, because there is no strength to be independent.

The Great Plain Ocean has the Northern Mariana Islands.

The Pacific Ocean is surrounded by Polynesia. The three major archipelagos of Micronesia and Melanesia can be divided into three categories: mainland islands, volcanic islands and coral islands.

The Pacific Islands are composed of more than 10,000 islands of different sizes, which can be divided into two categories: continental islands and ocean islands, and ocean islands can be divided into two types: volcanic islands and coral islands. Mainland islands are similar or connected with the mainland in terms of geological structure, generally located near the mainland, originally part of the continent, and later separated from the mainland due to crustal subsidence or sea level rise, such as Irian Island, New Zealand's South Island, North Island, etc. Such islands are generally larger in size and higher in terrain.

Volcanic islands are formed by the accumulation of volcanic eruptions on the ocean floor, mainly lava, such as the Hawaiian Islands in the Polynesian archipelago, which are still active today, and are characterized by high altitudes and steep terrain. Coral islands are islands formed by coral reefs outcropping out of the sea, or sand islands formed on coral reefs.

Most of the three archipelagos in the Pacific Ocean are coral islands, which are characterized by their small size, low terrain, and many ring-shaped shapes. In the middle is the lagoon, there is a gap to communicate with the ocean, the lake is calm and calm, is an excellent haven for ships. Coral reefs are formed by the accumulation of the remains of polyps.

The polyp is a coelenterate that lives in shallow tropical seas with an average water temperature of 25° 30 and high salt content and transparency, and after death the calcareous bones form limestone. At first, coral grows around the island to form a fringing reef, but as the island sinks, the coral reef continues to grow outward and upward, forming a barrier reef, and when the island continues to sink and submerge into the sea, the coral reef around the island grows upwards to form an atoll, and the top of the island is submerged by the sea to become a lagoon.

The Pacific Ocean remains an unconquered sea. It is larger than all the landmasses on Earth combined, and is dotted with more than 25,000 islands, large and small, half of which are still uninhabited.

There are many islands that do not have names, and there are many cases where there are more than one island.

Therefore, it is not possible to count the names of the ].
