Why can t the earth be inseparable from the sun Is the earth inseparable from the sun?

Because the mass of the sun is huge, much larger than the mass of the earth, the distance between the earth and the sun is within the gravitational range of the sun, and the kinetic energy of the earth has not reached the escape speed of the earth's gravity. So the earth cannot do without the sun.

On the other hand, most of the energy for life on earth and the movement of all things comes from the sun. That is, without the sun, the earth would be as silent as death.

Objective is because of gravity.

Subjective because the life of the earth needs sunlight to survive.

Because of the effect of gravity, and the acceleration of the earth not breaking free from the gravitational pull of the sun, let's stay honest. Without the sun, none of us would want to live.

It's because of gravity, I haven't learned it yet, what grade are you in?

If you're young, I'll give you an analogy"It's like a child can't live without his mother"Now you can understand it this way, and you will know it when you go to middle school and study physics.

There is a gravitational cause, but more importantly, do you know how hot the Earth will drop once you leave the sun?

I don't dare to say absolute zero, but it must be an environment where humans cannot live.

Plants need the sun for photosynthesis, and people also rely on the sun to kill bacteria, if there is no sun, the world is dark, and no living things grow.

The Earth is part of the solar system, and without the Earth, the internal gravitational system of the entire solar system would have changed, and it might not be what it is now.

The sun is the vast majority of the earth's energy, and it's over if you leave.

The earth needs gravity and heat.

Without the sun, we would know how to die, and the world would be plunged into darkness.

There are many more, but there is no information for the time being.

Can you leave Earth? A truth.

In addition to plants that cannot do without the sun, we humans cannot do without the sun.

During a week of losing sunlight, the Earth's average surface temperature will drop to low. The sea will freeze.

But because the ice on the surface of the ocean forms a well-functioning insulator, the deep water below the shallow zone will not freeze for millennia. A million years later.

The Earth on which the organisms depend will reach a relatively stable minus 240 degrees Celsius. This is because the heat emitted by the temperature from the Earth's core is equal to the radiation from space.

Plants that rely on photosynthesis will lose energy**, and most plants will die within a few weeks. Most of the living beings will disappear because of the disappearance of sunlight, and everything will be dead and silent.

Inseparable from. Due to the presence of gravitational force, the earth is confined to its orbit by the gravitational force of the sun and cannot leave.

1. The original balance of forces will be disrupted, which will cause a change in the motion of the earth, depending on the state and direction when it is just away from the sun.

2. It is possible to move to a more massive black hole, or to re-form a new equilibrium state. 3. The natural world on Earth will be destroyed and rebuilt, and new natural world and its corresponding acrylic ecosystem may emerge. 4. The old oak may perish and disappear.

Because the sun brings light and heat to everything on earth. Without sunlight, there would be no animals, plants, microorganisms, and all life activities on the earth, including human beings. Without the sun, photovoltaic, wind power, tidal power on Earth would not be able to be manufactured.

Without the sun, there would be nothing on earth.

In order to survive, human beings must find new alternative energy sources, and solar energy is inexhaustible, and the life span of the sun is estimated by scientists to be hundreds of millions of years, so there is plenty of time to find new energy sources that can meet the needs of survival.

The function of the sun

The sun does not produce spring blind exhaust gases, and can be ...... with solar energy, solar cars, and solar watchesThese save electricity, water, and the environment.

Sunlight shining on ** will dilate the subcutaneous blood vessels, increase blood flow, increase the excretion and resistance of toxic substances, and the nuclear branch will also increase the secretion of saliva and gastric juice, strengthen gastrointestinal peristalsis, and promote appetite and digestion.

**It can also produce vitamin D from some chemicals, such as ergosol and cholesterol, when exposed to sunlight. This vitamin, calcium and phosphorus, which are important components of bones, can lead to cartilage sensitization.

The sun is an important energy source for life on Earth**, and many organisms rely on the sun for productive activities such as photosynthesis, heat regulation, and more. Here are some examples of creatures that can't do without the sun:

Plants: Plants convert solar energy into chemical energy through photosynthesis to produce the nutrients they need. The sun, light, and temperature also control the growth and flowering time of the plants.

Without the sun, plants cannot photosynthesize, survive, reproduce, and provide food for other organisms.

Marine life: Most of the food chain of marine life is based on exponential photosynthesis. Plankton and seaweed need sunlight for photosynthesis and food for other marine organisms.

Some marine organisms are also sensitive to the photoperiodicity of the sun, such as certain sea turtles, starfish, corals, etc.

To sum up, the sun is very important for the reproduction and survival of life on earth, and many living things are inseparable from the light energy and heat of the sun.

Our solar system will soon collapse,Because the gravitational field of the Sun will disappear, all the planets and stars will be thrown out of the solar system by inertia, and eight minutes after the Sun disappears, the Earth will appear in the same state. Without the sun, the temperature of the Earth's surface would drop rapidly, the average temperature would continue to drop, and almost all surface water would freeze, including the vast oceans.

Most creatures die quickly. Only those resilient creatures will survive for a while, but the temperature on the Earth's surface will eventually drop above minus 200 degrees, and there is no doubt that what awaits them will be the end of death.

Relevant knowledge

If there is no sun, not to mention the human beings on the earth, even the earth has no support, because the earth will lose the powerful force that can pull it to run, and the earth's orbit will lose its center, that is to say, the earth will break away from the existing orbit and fly forward in a straight line, the temperature above will quickly cool, and the sky will quickly darken, a complete apocalyptic scene.

Not only the Earth, but if the Sun didn't exist, everything in the solar system would fall apart, and like a big planet like Jupiter and Saturn, if the Earth were lucky enough to run into one of the four giant planets of Jupiter, Saturn, Uranus, and Neptune.

Then it will become their satellites and begin to orbit them, which means that the earth will change masters, but these "masters" will not shine, and the earth will be downgraded from the level of a planet to a satellite.

If the Earth doesn't touch anything, then it will keep flying forward and become a lonely dark planet in space, and it will go through space for a long time, until one day it meets a larger body that can take it in, and it will orbit around that body, and if the other party is a star like the sun, then it may be a new beginning for the Earth.
