What grows all year round?

The characteristics of the four seasons of the year are:

Spring is the first season of the year, when the snow and ice begin to melt and everything recovers. In this warm and cold season, everything has just begun, everything is so fresh, full of vitality, and flowers are red and willow green everywhere.

Summer is the second season of the year, with the scorching sun and the enthusiasm of worship. Heavy rain often turned the whole city upside down, and after a while, the sun dried up the rain, and it was so duffy that people were drowsy all day.

Autumn is the third season of the year, with cool breezes and crisp autumn air. Autumn is always cool, and the autumn breeze blows through it with a chilling feeling. The dry air loses the stuffiness of summer, and a deep breath of clean and cool air makes you feel refreshed.

Winter is the last season of the year, with thousands of miles of ice and snow. Every day when winter comes, everyone is so cold that they want to hide under the covers all the time. Flowers, trees, fish, insects, birds and beasts have all disappeared.

Changes in the Seasons:

From the summer solstice through the autumn equinox to the winter solstice, the northern hemisphere changes from summer to winter, and the southern hemisphere changes from winter to summer. During this period, the days in the Northern Hemisphere became shorter, the nights became longer, and the polar diurnal zone gradually shrank. In the Southern Hemisphere, the days are getting longer, the nights are getting shorter, and the polar night zone is shrinking.

The height of the Sun decreases north of the Tropic of Cancer and increases south of the Tropic of Capricorn. North of the Tropic of Capricorn, the rising direction of the sun changes from northeast to southeast, and the direction of falling changes from northwest to southwest. The autumnal equinox rises due east and sets due west.

From the winter solstice through the spring equinox to the summer solstice, the northern hemisphere changes from winter to summer, and the southern hemisphere changes from summer to winter. The variations in the length of day and night, polar day and night, and solar altitude in the northern and southern hemispheres are reversed. North of the Tropic of Capricorn, the direction of the sun rises from southeast to northeast, and the direction of setting changes from southwest to northwest.

From the winter solstice to the vernal equinox and from the summer solstice to the autumnal equinox, the length of the day is approaching the average (12 hours) around the world, and the range of polar day and night is gradually decreasing. The height of the Sun north of the Tropic of Cancer and south of the Tropic of Cancer is approaching the mean. North of the Tropic of Capricorn, the sun rises in a direction that gradually approaches due east and sets in a direction that is close to due west.

The scope of the questions is too broad and too broad. Many things are used all year round, such as water, air, food, houses, beds, chairs, sofas, clothes, shoes, 、......In detail, it's really impossible to count.

There are two basic motions of the Earth's gaze ball, one is called rotation – the rotation of the Earth itself, and the other is called revolution – the rotation around the Sun. The rotation is carried out around the Earth's axis that passes through the north and south poles, and the direction is from west to east, and the farther away from the poles, the faster the transcoding speed. The circle equidistant from the poles is called the equator.

The time of one rotation of the Earth is one day, which is 24 hours. The Earth's orbit around the Sun is 30 kilometers per second, and it takes 365 days, 5 hours, 48 minutes and 46 seconds to orbit the Sun. That is, a year, which is called a return year in astronomy.

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 summer in the southern hemisphere, and summer in the northern hemisphere and winter in the southern hemisphere at aphelion. This shows that the change of the seasons is independent of perihelion and aphelion.

So how did the change of seasons come about? It is related to the revolution, but the decisive condition is that the earth must revolve diagonally around the sun; If the Earth rotates vertically around the Sun, the Sun's rays will always shine directly near the Earth's equator, while elsewhere the ground level and the Sun's rays will grind later.

is a natural formation.

It's about sunshine and so on.

Isn't it naturally formed? I often hear that God manages it and eats from the sky.

Not necessarily every place has four seasons of the year For example, near the equator, the equator is the hottest in the spring equinox and the autumn equinox, and the summer solstice is the coldest after the winter solstice, for example, in the Arctic Circle, the autumn equinox to the spring equinox is eternal night, and the spring equinox to the autumn equinox is eternal day Taiwan is located in the subtropics Winter is not too cold in comparison The four seasons are the temperate zone For example, Europe In simple terms, the earth revolves around the sun, but the angle of inclination of the earth's axis remains the same, so if the northern hemisphere is now far away from the sun (winter), it will become close to the sun (summer after half a year) to**Playing the four seasons**Oh.

Everything is a fixed law, and the specifics have not been understood.

Since the rotation plane is the ecliptic plane, the rotation plane equatorial plane forms a yellow-red intersection angle with an angle of 23 degrees 26 minutes. As a result, the direct point of the sun moves, and the direct point moves between the two lines of cancer within a year, and the heat received in a year is inadvertently unacceptable, and then the four seasons are formed.

The direct sun area is between the Tropic of Capricorn and the Tropic of Capricorn, so the sun in this area is always nearly direct, so the energy obtained from the sun in a year is higher and late, resulting in a higher temperature in the region, which does not change much in a year, and the region is called the tropics. In the tropics, there are no changes in the four seasons, and it is summer. It usually refers to the four seasons of the year, which are mainly expressed in the temperate zone, that is, the area between the Tropic of Cancer and the Tropic of Cancer and the Antarctic Circle from the Tropic of Cancer to the Antarctic Circle.

The Antarctic Circle is the southernmost line of latitude that the Sun can illuminate when it hits the Tropic of Capricorn, that is, the southern latitude (the latitude of latitude and the latitude of the Tropic of Capricorn are mutually congruent). Similarly, the Arctic Circle is located at northern latitudes. In the polar circles, there will be polar night and polar day.

Obviously, in the summer in the Northern Hemisphere, there is a polar day phenomenon in the Arctic Circle and a polar night phenomenon in the Antarctic Circle. Conversely, when it is summer in the Southern Hemisphere, the polar night phenomenon occurs in the Arctic Circle and the polar day phenomenon occurs in the Antarctic Circle.

1. The four judgments know that the seasons are due to the earth's rotational movement. The Earth revolves around the Sun. Rotate in one circle, and this motion is called the earth's rotational motion. The Earth's orbital motion causes the Earth's surface to receive more or less sunlight and heat.

2. Areas with latitude below degrees. The year-round heat has become the tropics of the earth. The area above the latitude of the digging is cold all year round and becomes the cold zone.

A reed crossing again to the area between degrees. It came into being as the Earth revolves around the Sun. There may be little calorie.

Thus the earth's slashing spring, summer, autumn and winter are formed.
