The position of the Earth in relation to the Sun and the seasons

Of course it is true, the perihelion of the Earth is at the beginning of January, and the aphelion is at the beginning of July. But to be precise, the Earth is "our" winter when it is at perihelion, because our winter is summer in the Southern Hemisphere, and the seasons in the Northern and Southern Hemispheres are reversed.

From this alone, it should be seen that the distance between the earth and the sun is not the main cause of seasonal changes, but the periodic changes in the height of the sun and the length of sunshine.

The distance between the sun and the earth affects the amount of solar energy obtained by the world, but the share of these energy distributed on the earth is different from place to place, and the area with high sun altitude and long sunshine can distribute more, which is summer.

Winter is near; Summer is far ..There is a certain inclination, so that the solar energy that can be absorbed per unit area is greatly reduced! In contrast, in summer, the earth is at aphelion, but the earth absorbs solar energy at a high rate, so the temperature is also high.

The straight line of the two focal points and the two focal points of the ellipse correspond to the perihelion and aphelion respectively, as the name suggests

In winter, the earth goes around perihelion, and in summer, it reaches aphelion

on the world map.

Find the Tropic of Capricorn and the Tropic of Cancer.

In winter, the sun's rays shine directly on the Tropic of Capricorn, and because China is in the northern hemisphere, it is oblique to move away from the sun. In summer, the sun shines directly on the Tropic of Capricorn, which is closer to the sun because China is in the northern hemisphere

Almost straight shots .

So on the ground, when the rise is highest, it will be a little higher in the summer.

Summer is around the beginning of July – aphelion, when the Earth is far from the Sun.

Winter is around the beginning of January – perihelion, when the Earth is close to the Sun.

This is the theory. It can be seen that summer and winter are divided according to the solar heat obtained by the earth, and not according to the "distance of the earth from the sun".

It's not that it's close to the sun and gets hot; It is getting colder away from the sun.

Early January – perihelion – Northern Hemisphere winter.

Southern Hemisphere summer.

Early July – aphelion – Northern Hemisphere summer.

Southern Hemisphere Winter.

Summary. It has something to do with the movement of the earth around the sun.

Because the change of the seasons is related to the co-rotation of the earth.

The alternation of day and night is related to the rotation of the earth.

Is there a relationship between the angle of sunlight in the four seasons and the movement of the earth around the sun?

It has something to do with the movement of the earth around the sun. Because the change of the seasons is related to the co-rotation of the earth. The alternation of day and night is related to the rotation of the earth.

The Earth's motion around the Sun is its revolution. Therefore, the change of the 4 seasons is related to the movement of the earth around the sun.

The rotation of the earth forms day and night, and the rotation of the earth forms the four seasons of spring, summer, autumn and winter. The absence of four seasons means that the Earth's orbit around the Sun is perfectly circular.

For the earth, Taiyou Jimiyang is the only energy source to obtain the land of filial piety.

If the Earth's orbit around the Sun is perfectly circular, then the northern and southern hemispheres will produce different constant temperature zones, and unless the Sun's energy fluctuates regularly or irregularly, it is possible to cause regular or irregular changes in the temperature of the different constant temperature zones on the Earth.

It is precisely because of this relationship that whether the Earth's orbit around the Sun is perfectly circular or not, it is concluded that solar illumination affects seasonal changes, and only when the temperature front of sunlight is changed back to a certain temperature can the Earth return to a certain season.

So, energy can be conserved or not, but if you need it to come back to a certain interval, you have to make the energy change in different properties.

Energy is the root cause of any change.

The angle of inclination of the earth to the orbit is that the rotation of the earth produces four seasons, and if the earth is not tilted, it will not produce four seasons

Winter. The Earth's orbit around the Sun is an ellipse that is not much different from its long and short diameters, and can be approximated as a perfect circle. The sun is at one of the focal points of this ellipse, and the focus is not in the center of the ellipse, so the distance between the earth and the sun is sometimes a little closer, sometimes a little farther away.

At the beginning of January, the Earth is closest to the Sun at 147,100,000 kilometers, which is called perihelion. At the beginning of July, the Earth is farthest from the Sun, at 152,100,000 km, which is called aphelion.

In fact, when the Earth is at perihelion, it is winter in the Northern Hemisphere and the Southern Hemisphere.

It is summer, at aphelion, summer in the northern hemisphere and winter in the southern hemisphere. At perihelion, the Earth revolves.

Faster and slower at aphelion. At perihelion, the Earth receives solar radiation.

Stronger (closer), the average temperature of the Earth's entire atmosphere reached the highest of the year in January; But the lowest temperature is not at aphelion, but in October (and occasionally in September).

In winter, the Earth reaches the perihelion of the Sun during the winter solstice.
