Why won t the island sink? Why doesn t the island sink?

The island is originally connected to the bottom of the sea, and it is only possible to be submerged because of the sea level, how can it sink.

It turns out that since it is not floating, it naturally doesn't matter if it sinks.

The islands are not floating on the water at all

Rather, it has its own foundation, which grows on the crust of the sea. (Of course, how long is another question, Hussen).

Therefore, the islands cannot be explained by floating and sinking, and they are not next to each other at all. You might as well imagine a situation where there is a basin, and you fill it with water, and you put a stone higher than the basin in the basin, and the stone is sinking in the water, but now it is exposed, and this is what it feels like.

As we all know, although Japan has a strong economy and is currently the third largest economy in the world, its development potential has been greatly limited because it is an island country with an area of only more than 300,000 square kilometers. In addition, because Japan is an island country, it is often threatened by various natural disasters such as tsunamis**, so it can be said that Japan is a country with frequent natural disasters.

There are even many people who believe that Japan may even sink in the future, is this true?

In this regard, some experts said: for this reason, the future will be inevitable! What is it that makes Japan's sinking future inevitable? That is, Japan's continental plate is very close to the Mariana Trench, the deepest in the world, and Japan's continental plate moves slowly every year.

However, it is inevitable that if Japan's continental plate breaks or continues to move towards the Mariana Trench, it will lead to the sinking of part of Japan's territory in the future. After all, Japan is only an island country, not a continental country with a huge continental shelf like China and Russia.

In addition to this, there is a very important reason, and that is the rise in sea levels due to global warming.

As the global climate continues to warm, the Antarctic and Arctic ice melts and sea levels are rising. As an island nation, Japan will be affected more than its landlocked counterparts, and if the trend of global warming does not change in the future, sooner or later, part of Japan's territory will be submerged by sea level.

At that time, Japan will be much smaller.

This shows how much of an island nation is disadvantaged, not only because of the limited land area, which affects economic development, but also because of the danger of being submerged by rising sea levels.

However, it will be at least a long time before such a situation comes, so there is still time for humans to change this, and as long as the environment is well protected, it is not impossible to change this trend in the future.

The archipelago may sink because of tectonic plate movements, but it won't happen anytime soon.

Japan does not sink, but continues to grow and rise, and in the process of the overall uplift, there are only a few small subsidence faults, but they will soon be filled.

China is a large-scale regional subsidence! Because the marginal sea, which is located on the inner side of the continental island arc, is constantly passively compressing and sinking. The Changbai Mountains, Shandong Peninsula, Taihang Mountains and the Korean Mountains are the rising zone, and the corresponding Liaohe Plain, Songnen Plain, North China Plain, Yellow Sea, East China Sea and Fenwei Plain are all subsidence zones.

China is one of the countries with the most serious land subsidence. The proportion of population and GDP living in lowlands below 10 meters above sea level is much higher than that of most of Japan's Pearl River Delta, the coastal plains around the Bohai Sea, most of Jiangsu, and most of Shanghai and northern Zhejiang.

More than 200 million people live in the lowlands! Note: The coast is not equal to the lowlands, look at the land below 10 meters above sea level in Japan, except for the reclaimed part, which is basically a piled plain near the sea, and the densely populated parts of major cities are basically above 10 meters above sea level; In New York, USA, only a small part of the lower city and the reclaimed part of the sea are less than 10 meters above sea level, and most of the entire main urban area of New York is above 30 meters above sea level.

China's major cities such as Shanghai, Tianjin, and Guangzhou are almost all below 10 meters above sea level, extending hundreds of kilometers from the coast to the interior. Ten meters above sea level is the limit of storm surges, tides, etc., and is about the limit of susceptibility to salty tides. Without continuous replenishment of sediment material, these lowlands will sink to the bottom of the ocean in the near future (within a few hundred years) as the ground subsides gradually.

In the period of global warming and rising temperatures, human beings are paying a lot of attention to glaciers in Antarctica, the Arctic and other regions. Recently, the scientific community announced that it will investigate and maintain the world's most dangerous glacier in the southwest corner of Antarctica.

According to scientific sources, scientists from the United States and the United Kingdom have officially launched a project to investigate the Thwaites Glacier, to find out whether the collapse of the glacier will bring catastrophic questions to mankind in the future, the glacier is melting at an accelerated rate while global warming, and the rise in sea level is also a major threat to human islands and coastal areas.

According to the British scientific community, the Thwaites glacier is melting at a rate of about 40 centimeters per year, and sea levels are expected to rise by about 4% over a 25-year period. It seems that the data is small, but compared to 4% of the sea level, there will be more one after another, which is what scientists are most worried about, this is only a preliminary ** result, and more unknown factors still exist.

Scientists say that if a more serious situation occurs, the estimates will be even larger. The projected result is 25 years, and sea levels could rise by 2 to 10 feet (60 to 300 centimeters), warnings say. The highest case is the case that reaches 3 meters.

According to the latest scientific data, more than 1,000 low-lying tropical islands in the world, Roi-Namur and surrounding islands are only meters above sea level, and some of these islands will disappear completely.

The glacier survey of the project is the largest Antarctic cooperation in decades, involving more than 100 scientists and consuming more than $55 million.

The scientific community is paying more and more attention to environmental changes, and we have to admit that there are indeed changes in our global environment, and in time to put aside the problem of glacier melting caused by global warming, there are more problems such as heavy rain, high temperature, drought, etc., which are one of the environmental problems caused by natural changes, so protecting the environment is the most serious problem in the current scientific community.

Rising sea levels can sink islands completely, as rising sea levels will cause them to get lower and lower, and eventually the sea will flood the entire island.

If the sea level is always rising, the island will be completely submerged. Because in this case, a lot of things on the island will be flooded by the sea, and the ground will continue to sink.

Rising sea levels can completely sink some of the Earth's islands, such as the Maldives archipelago.

But there are also some islands at higher elevations that will not sink completely, such as Madagascar.
