In summer, the sky is early, and in winter, it is late

This is related to the hemisphere in which the sun is located, and in summer, the sun shines directly on the northern hemisphere.

Therefore, the days are longer and the daylight is early. In winter, it hits the southern hemisphere, so the day dawns late.

The reason why the sun is bright early in summer and late in winter is because there is an angle between the earth's axis of rotation and the plane of the earth's orbit around the sun, and the sun directly hits the earth at different positions in different seasons, so the sunshine duration and sunrise and sunset times are different in different seasons. In summer, when the sun shines directly near the Tropic of Capricorn, the days are longer and the nights are shorter in the northern hemisphere, and the days are short and the nights are longer in the southern hemisphere, so the days are earlier in summer and later in winter.

Such. The sun is at its highest in the summer, especially on the summer solstice (the direct point of the sun is the Tropic of Cancer in the Northern Hemisphere, so if you live in the Northern Hemisphere, your solar height is the highest. So that the days are longer.

And in winter, the winter solstice (the direct point of the sun is the Tropic of Cancer in the southern hemisphere, so that the days in the northern hemisphere are shorter. So the end of the rise. Also because the earth is autobiographed, this is also related, and in January, the earth's rotation speed is faster, and in summer, it is slower.

Because the earth itself revolves around the sun, in winter the sun is located on the south side of the earth, and the light hours are short, that is, the daylight will become shorter, the day will be late and the darkness will be early. In winter, the time of daylight varies depending on the region, but in most areas it is around half past six, and in the western region it will be a little later, not more than half past seven at the latest.

There are many factors that affect sunrise, mainly including longitude, latitude, and altitude. In winter, the higher the dimension, the later the dawn will be, which is why around the North Pole or the South Pole, there will be a polar day or a polar night. Similarly, the higher the altitude, the earlier you will see the sunrise.

The day starts a little earlier and the night starts to get a little later.

The winter solstice around December 21 is in the Northern Hemisphere.

The shortest day of the year and the longest night. After this day, the days become longer and the nights shorter throughout the Northern Hemisphere. The length of the day is divided into morning and afternoon at 12 o'clock. These two parts are equal in length. If the day gets longer, the afternoon will get longer.

Because the sun shines directly on the Tropic of Capricorn after the winter solstice.

So the sun moves southward, and the sun's light depends on the position of the sun. In winter, the northerly the sun moves, the northerly the direct point of the sun becomes. Therefore, China is in the northern hemisphere, so in winter the days are short and the nights are long.

Because of the Earth's axis. It is oblique, so the length of day and night is different in different places on the earth. In the polar regions of the Earth, the sun is skewed throughout the year, and the length of day and night varies the most.

in the Northern Hemisphere and the Southern Hemisphere.

At high latitudes, the sun does not set or rise all day. In other words, 24 hours a day is either day or night. In the polar regions, this is known as polar day.

and Polar Night. In the North and South Poles, there are six months of day and night.
