What would happen to the earth if all the sea froze?

The sea water is all frozen, the first direct impact is the organisms in the ocean, the oxygen contained in the water in the ocean, a large part is integrated by the sea water when it is in contact with the air, a small part is produced by marine plants, after the sea water freezes, the sea water can not be in contact with the air, the oxygen content is inevitable, without sufficient oxygen, the death of marine animals is difficult to avoid, whales and other animals that breathe by the lungs are dead faster, the death of a large number of marine animals will definitely cause marine pollution, the ocean will become a pool of stagnant water, A pool of stagnant water that spans the globe. Marine animals that do not die of lack of oxygen may eventually die of starvation, because when the sea freezes, the activity of ocean currents will inevitably weaken, and without the surge of ocean currents, microorganisms, plankton and other bait will not be able to float in the water, and fish may starve to death without food.

This is all more terrifying. It is hard to imagine how long it will take for the Earth to freeze seawater at depths such as the Mariana Trench. It is imagined that the sea water is more difficult to freeze because of its higher salinity.

Then it depends on how much the temperature is reduced. If slow freezing is long enough, more fresh water may freeze on land, while the atmosphere with higher water content will also snowfall heavily. Causes land to freeze.

The sea level rises because of the buoyancy of the sea on the ice, and the entire ocean freezes. Then the squeeze of each land plate is smaller. With the temperature set lower, it should indeed cause a squeeze on the continent.

It may resemble the uplift of new mountain ranges caused by the collision of the Eurasian plates.

If all the sea freezes, the earth will become a big ice rink, and there will be severe cold everywhere, and the cold winter will make people unable to survive, and people will all go extinct.

If all the sea freezes, the earth may become an ice rink, because there are still many cities with seas, and the sea occupies a large area of the earth.

Because the area of Shanghai is not very large, even if the sea water is all frozen, then the land area can still live, and the earth will not change much.

The land area on the earth is not very large, more than half of it is seawater, and if all the sea water freezes, the earth will become a large ice rink.

The earth will also freeze over, because more than half of the earth is seawater, and the continents are very small, and if all the water on the earth freezes, the earth will become an ice hockey ball.

If all the sea freezes, the sea level will drop, and in some places it will be very dry, the drought will be severe, the crops will not be harvested, and people will go hungry.

If all the sea water freezes, then there will be a shortage of many marine life on the earth, and some human food will also cause shortages, and the food chain will cause a certain shortage.

I think that when the sea freezes completely, the earth will become barren and lifeless, because the sea is an indispensable part of the earth, and we humans and all kinds of animals will no longer exist.

I don't know, it should be frozen, and then thousands of years later, the earth will be resurrected, new species will appear, and then dominate the earth and create a new civilization.

The world will be very starved of water, and it will be difficult for people to survive, not only humans, but also animals, and the earth will dry up.

It is estimated that the end of the world is not far away, the ecology is seriously damaged, and the earth is destroyed.

Hello subject! In that case, the global climate will change dramatically, the natural environment will change, and it will become a veritable ice hockey puck.

If you still sleep and take screenshots, most of the earth will turn white, and if we look at the earth in the universe, it won't be blue and it will become white.

That would be a catastrophe, and if the sea freezes, the global temperature will no longer be suitable for human habitation.

When the world gets cold, the whole world will be very cold, which is not a good phenomenon, and people will become much lazier in winter.

The earth will enter an extremely cold state, a large part of the earth is water, and all of it will freeze into ice, and we humans will not be able to survive.

What if all the earth's waters were turned into fresh water? The scientist's explanation came as a surprise.

If all the oceans on Earth froze, the Earth's water cycle would be very problematic and rainfall would decrease, making drought a very common natural disaster.

I think the world will go back to the Ice Age, because it is impossible to freeze only the oceans and not the land.

Then all living things will face food shortages and calorie shortages, leading to the extinction and death of a large number of species.

Seawater can freeze, of course, but the situation is more complicated than freshwater. The density of pure water increases with the decrease of temperature, but decreases with the decrease of temperature when it reaches below 4. When the air temperature decreases, the surface water temperature drops, the density increases, and it sinks, causing convection.

Until the total water temperature is reduced to 4, the convection stops, and the surface continues to cool until 0 begins to freeze.

When the salinity is lower than the salt content, the seawater behaves similarly to freshwater, convection, reaches the maximum density temperature, the convection stops, and the upper layer freezes;When salinity happens to be, the maximum density temperature and freezing point are;When the salinity is greater than the salinity of the sea water in the open ocean, which is usually around 30), the sea water will continue to convection before the whole reaches the freezing point, so it is difficult to freeze. However, in the nearshore area, due to the shallow water depth and the small scale of convection, the sea can freeze quickly when the temperature drops dramatically, such as during a strong cold wave.

1) The existence of monsoons and ocean currents enables the sea water to exchange heat energy, from the equator to the poles or from the poles to the equator, the ocean is generally connected, the four oceans they are a whole, and there is a certain balance of heat transfer. 2) The salinity of seawater is very high, which lowers the freezing point of seawater. Freshwater freezes at 0 degrees Celsius, with a freezing point of water with 10 salinity, while water with 35 salinity has a freezing point.

The average salinity of the seawater in the oceans of the earth is, therefore, the freezing point of the seawater is around the limit. 3) The maximum density of seawater is not at 4, but decreases with increasing salinity. It decreases faster than the freezing point decreases with increasing salinity.

As you can see from the graph below, the two descending lines intersect at the coordinates of salinity. Because the average salinity of seawater is much exceeded, when the seawater reaches the freezing point, it has not yet reached the maximum density of seawater, so the convective mixing of seawater does not stop, which greatly hinders the freezing of seawater.
