Anonymous users2024-02-06The reason is that there is space isolation and atmospheric protection on the surface of the earth. As we all know, the closer you are to a heat source, the hotter you will get. The farther you go, the heat transfer is blocked by the distance.
The distance between the Earth and the Sun is just right. It can absorb heat sources without getting too hot. This, combined with atmospheric protection like a protective film, will allow the Earth to store heat and sequester excess heat.
In addition, there are many heat carriers on Earth, such as water and hydrogen, which are excellent thermal insulation measures.
First, let's talk about the temperature of the sun. Because Hengyang is a luminous body, it can emit light and heat on its own。Its surface temperature is as high as 5.8 million, and the core temperature is as high as 20 million, which shows how hot the sun is!
When the Earth's surface temperature exceeds 30 degrees Celsius, people feel hot and dry. When the temperature rises to 40 degrees Celsius, the feeling of dry heat becomes more indescribable. Many people have been killed or injured in India this summer due to high temperatures above 50 degrees.
So where does the Earth's temperature come from? Nature comes from the sun!
However, the space between the Earth and the Sun is in a complete vacuum。There is no carrier to store heat in a vacuum environment, which makes the space colder. The heat that remains in a vacuum environment is not lacking, but penetrates it directly.
Just as the astronaut's spacesuit not only guarantees the best of oxygen, but also guarantees that it will not be affected by a vacuum environment. Thus, the sun transfers temperature to the earth, but the space between the sun and the earth is cold!
According to relevant data, the Sun is about 100 million years old, while the Earth is about 4 billion years old. For 4 billion years, the sun's rays have nurtured countless life on Earth, which is why the Earth gets its temperature from the sun at the same time as it has its temperature.

Anonymous users2024-02-05Because there is a vacuum between the Earth and the Sun, there is no medium between them that can propagate temperature, so there is no temperature in space.

Anonymous users2024-02-04Because there is no air, no water and no soil in space, it cannot absorb the heat transferred by the sun.

Anonymous users2024-02-03That's because the space between the earth and the sun is vacuum, and the vacuum environment cannot store any heat, and the light and heat are directly transmitted to the earth through the vacuum. So it's very cold in space, without the slightest temperature.

High solar temperature: It depends on the weather and the degree of water. Generally, the maximum temperature of solar water heaters is 98 degrees Celsius in an environment with little water on sunny days (low water level). >>>More
In fact, when the universe was first born, it was not cold, not only was it not cold, but it was also extremely hot, but the skyrocketing space quickly caused the temperature of the universe to drop to the level of matter formation! Of course, the skyrocketing has not stopped, and the universe is gradually cooling down, until now the cosmic microwave background radiation is about 3k. >>>More
As we all know, the earth has undergone many geological activities since its inception, and the eruption of volcanoes has made us understand that the interior of the earth is hot。After geologists surveyed, we also know that under the land we walk, not only is there hot magma flowing, but also a large amount of radioactive elements that are decaying. >>>More
We often say that Jupiter is the patron saint of life on Earth, but what about our nearest celestial body, the Moon? In fact, it is also our patron saint. Jupiter is also 100 million kilometers away when it is closest to us, much farther than the Sun. >>>More
