How the Earth s temperature rises, the snow and ice melt, the sea level rises, and the speed of the

The moment of inertia of the earth will become larger and the speed of rotation will be slower. Moment of inertia refers to the measure of the rotational inertia of a rigid body about its axis. Also known as distance of inertia and moment of inertia (commonly known as distance of inertia and moment of inertia) Its value is J = Mi*ri 2, where mi represents the mass of a certain particle of the rigid body, and ri represents the vertical distance from the particle to the axis of rotation.

That is, the moment of inertia of the Earth is the sum of the mass of each mass on the Earth multiplied by the square of the distance from that particle to the axis of rotation of the Earth. As the Earth's temperature rises, icebergs near the North and South Poles will turn into water and distribute equally among the Earth's oceans. The particles near the north and south poles are very close to the earth's axis of rotation, that is, the radius of rotation is very small, so the moment of inertia of each particle is very small.

When these particles (which become water) move away from the poles, their radius of rotation increases, especially when they reach the point near the equator, where the radius of rotation is the largest, so their moment of inertia also increases. When a large number of icebergs melt into water and flow to other regions, the moment of inertia of the earth will increase significantly. The rotation of the earth is a fixed axis rotation, and the axis of rotation is the line between two poles.

Fixed axis moment of inertia of the mass = mr 2. If it is not a particle, it should be integrated by position using the above formula. Obviously, objects at the two levels are close to the shaft, and objects in other areas are far from the shaft.

The melting of glaciers is equivalent to transferring the mass of the two stages to other parts of the earth, so it will cause r to become larger, so the total integrated amount will become larger, that is, the moment of inertia will become larger. To put it simply, it is due to the change in the mass distribution, which leads to an increase in the moment of inertia. The Earth's inertia increases, and the rotation speed slows down according to the conservation of angular momentum.

This is also the reason why the legend says that the Spring Festival will affect the rotation of the earth. Imagine that the north and south poles are in the axis position, then the glaciers on them are near the axis, and if they melt, the ice water will be dispersed from the poles to all parts of the country, and the centrifugal force will increase while the sea level rises! If you don't understand, make a big rotating disc and you stand in the center and you stand on the side to see which position can throw you out, and if you stand on the measuring side, the disc will become less unstable.

The increase in the temperature of the earth leads to the melting of snow and ice, which leads to a rise in sea levels. In addition, the Earth's rotation speed is also affected.

The increase in the Earth's temperature causes the snow and ice to melt, which makes the Earth's mass distribution more uneven, affecting the Earth's rotation speed. Specifically, melting snow and ice will cause the Earth's mass distribution to be more equator-skewed, which will lead to an increase in the Earth's rotation.

Therefore, an increase in the Earth's temperature causes the Earth's rotation speed to increase.

Assuming conditions, the land is all sunk and the earth is left with only the ocean.

1.Wind: Solar radiation.

As a result, the surface is heated unevenly, that is, the heating at low latitudes is large, and the heating at high latitudes is small. Plus the rotation of the Earth.

The monsoon circulation is formed.

2.Currents. Because there is no land to block it, the ocean current naturally does not have as many twists and turns. And because the wind blows the water, the direction of the current is about the same as the wind in the figure above. The North and South Poles may freeze due to temperature, and there is no widespread ocean current.

3.Climate: Also because of the different solar radiation received by the earth's surface, according to the above reasoning, it can be divided into three climatic zones, tropical marine climate.

Temperate oceanic climate, polar alpine climate.

Temperature: The specific heat capacity of water.

If the total global heat remains unchanged, the global temperature will drop. In other words, if we are still living in our current area, we will feel cooler than before, and the temperature difference between winter and summer will be smaller, and the daily temperature difference between day and night will be smaller.

Precipitation: It will be more frequent than before, because it is all oceans and the sun, and evaporation takes away a lot of water vapor, and the water vapor rises and condenses precipitation.

The climate will become very simple, the monsoon climate will disappear completely, leaving the climate related to the seasonal oscillation of the barometric wind belt.

In terms of ocean currents, the cold currents are all gone, and only warm currents that blow from the equator to the poles by wind (ocean currents sink after cooling at high latitudes and return to the tropical ocean in the deep sea). What is certain, however, is that the currents are significantly weaker in terms of intensity than in the present environment, and there are two super-strong circulations (westerly drifting and equatorial drifting--- and of course, there is still an equatorial countercurrent between the north and south equatorial drifts. ）

Global temperatures tend to get colder, but the equator is hotter and the poles are colder.

Because the temperature exchange between the global poles and the equator is blocked, the number of icebergs at the poles increases. Icebergs have a higher albedo rate. But at the same time, the oceans have much lower albetars than land, so tropical ocean surface temperatures will be much higher than they are now.

Considering that marine biological carbon emissions are not on the same order of magnitude as terrestrial organisms. So the other greenhouse gas CO is drastically reduced. As a result, the overall terrestrial temperature tends to decrease (the decrease in temperature objectively reduces the evaporation of HO, so the conclusion is that both greenhouse gases are less).

Greenhouse gases are rising, leading to global warming, and global warming is causing icebergs to melt. The melting of glaciers will lead to the emergence of viruses in ancient times, and it is conceivable that these viruses that have been deposited for hundreds of millions of years have radiated out, and their vitality is very strong, and the viruses have swept the world with seawater, and the harm is immeasurable. Of course, there is no land, there is no human being, and these are all chain reactions.

So we need to protect the planet and protect our home.

If all the land sinks, it means that all the surface of the earth is water, and the level of the earth is raised, and all the ground disappears and goes underwater.

The surface of the water acts like a mirror, reflecting back the light and heat from the sun.

The Earth's temperature will drop dramatically and the temperature will get colder.

If all the land sinks, I think the global temperature will be colder, and now a large part of the earth's warming is due to human factors, and the chance of the existence of silent people on land will be much smaller, at least carbon emissions will be greatly reduced, and the earth will only get cold without human activities.

The cause should be a smaller temperature difference. Because the Sebironone of the water is comparatively larger. If.

The Earth's atmosphere has not changed in the case. There is only one situation, that is, the summer is not very hot, and the winter is not very cold, and the temperature difference gradually becomes an oceanic climate. There will be no extreme heat and cold.

Of course, the North and South Poles are finished.

It will get cold, evaporate, cold snap, circulate ......Without vegetation, mountains, and rivers, it's only getting colder.

The ocean will be more likely to absorb the energy emitted by the sun, and the temperature difference between morning and evening will be smaller, and the temperature will be a little milder!

The total sinking of land and the melting of glaciers will increase the global sea level by a lot!

Since there is no land block, the current will flow more regularly!

If all the land sinks, how will carbon dioxide be consumed? The Earth should be hotter, carbon dioxide concentrations will rise dramatically, and the Earth will be raining heavy rain and hurricanes.

How can all the land be silent, the whole earth becomes an ocean climate, and how will the ocean currents change? Will global temperatures get colder or hotter? It's going to get colder, and the earth will disappear in the future, right? Definitely.

The climate is rising, the ocean currents are getting bigger, and the temperature is getting hotter.

The water level rises first, the glacier melts, then cools down, and then cools down slowly.

<> due to global climate change.

, rising global temperatures can cause glaciers to melt, which could lead to the Earth's rotation.

A slight slowdown. The driving force behind the slight but noticeable change in Earth's rotation measured by satellite and astronomical measurements is the flow of glacial meltwater into the oceans, causing global sea level rise.

This study observes that with global warming in the 20th century.

The Earth's rotation and axis of rotation are rising at global sea level.

Earth, Sun, and Moon.

The gravitational interaction between them is slowing down the Earth's rotation, but studies have shown that the Earth's rotation may accelerate or slow down in a short period of time due to various factors. Melting glaciers and rising sea levels are thought to be one of them. As glaciers melt, the Earth's mass shifts from the poles towards the equator, slowing down the Earth's rotation.

Since the melting of glaciers is irregular (water flows), it is believed that the earth is massive.

The irregular changes cause a slight shaking of the Earth's axis.

If we analyze the Earth carefully, we will see that the Earth revolves around the Sun and the Moon revolves around the Earth. The mass of the Moon should be less than that of the Earth. Although its gravitational pull is much lower than that of the Sun, it will play a role in the Earth and will still rely on gravity.

Some scholars speculate that this is related to the melting of glaciers in the Antarctic and Arctic. Over the past few decades, a large number of glaciers and ice caps have melted because of global warming. The Antarctic and the Arctic have a large number of glaciers and ice sheets, especially the Antarctic, which is the largest single ice on Earth.

The researchers analyzed the Earth's rotation and changes in the Earth's axis, both caused by rising global temperatures, from the perspective of global sea level rise in the 20th century. Melting ice sheets and rising sea levels have shifted the Earth's axis of rotation, with the North Humu pole shifting at a rate of 1 centimeter per year. The Earth is not a perfect sphere because it is in a rotating state and its structure is flat.

If it moves in the polar regions, the Earth will become flatter.

Without the system, the melting of glaciers in the Arctic and Antarctic only causes the temperature of the earth to become higher, and the mass of the earth itself is very large, and there is a great inertia when it is rotated, and it is not a glacier that can be changed.

It doesn't matter, the melting of glaciers in the North and South Poles will only affect the temperature and humidity of the earth, and will not affect the speed of rotation.

The slower the rotation speed of the earth, the faster the ice state of the North and South Poles will melt, so there is still a relationship between the two, and the two are also cause and effect.

The temperature on our planet is getting higher and higher, and in some areas, the maximum temperature has been exceeded this year, and this area is the Death Valley of the United States, which is also one of the warmest regions in the world. At such a temperature, it is still very difficult for us humans to live, because the temperature is too high, which will cause a large amount of water in our body, and a little carelessness will cause serious dehydration. So how much will the sea level rise if the global average temperature rises by one degree?

According to the study of the study meters. There are several reasons for this. <>

1. Global temperatures, which are now warming due to large amounts of human emissions. First of all, the first point is that the cause of global warming is that people are deforesting and emitting a lot of gases. Behind the cause is the loss of the temperature regulation function of plants, and the vegetation cover is also large, people use this part of the trees for housing construction, various wood products processing, or these originally forested areas for cultivation and agriculture.

After all, a large number of greenhouse gas emissions, the earth has not had time to digest these greenhouse gases in time, so it will lead to the important reason for the temperature rise caused by these gases. <>

Second, there are a large number of glaciers in the global Antarctic region. Secondly, there is another point about why a rise in global temperature will cause a rise in sea level of about meters. This is because there are a large number of glaciers in the Antarctic and Antarctic regions of the world, and all of these glaciers are water that was stored during the ice age.

If all of these glaciers melted, many of the islands would be submerged. <>

Third, human beings are also facing serious pressure to survive. The last point is that we human beings are also facing these serious existential pressures, we don't know when the earth will be destroyed, and what will be the impact of destruction on our human beings? I, the human race, have lost the land we live on now, so what should we do for the human race?

For every degree of rise, the sea level will rise by 6 meters, and many cities in coastal areas will be obscured, which is very scary, and I hope that human beings can control the temperature well and not damage the environment.

For every degree of rise in the Earth's average temperature, the sea level rises by 2 meters, as the increase in temperature leads to the thermal expansion of sea water and the melting of glaciers, resulting in a rise in sea water.

There are a large number of glaciers in the Antarctic region of the world, and the average temperature of the earth will rise, many glaciers will melt, and the average temperature of the earth will rise by about one meter.

A change in the speed of the Earth's rotation causes a change in the temperature of the sea water. （）

a.That's right. b.Mistake.

Correct answer: B

Summary. Soil erosion is a disaster that causes the duration of rainfall on the earth's surface to be prolonged, the intensity of rainfall increases, and the melting of ice and snow in the ocean is accelerated.
