How do the changes in the seasons affect us and the things around us?

The seasons have different effects on us and the things around us.

Spring: The wind and the sun are beautiful, comfortable and pleasant, refreshing, people are lightly dressed and outing, and farmers are busy with spring ploughing.

Summer: Busy wheat harvest and summer planting, fruit ripening, lotus blooming, and gradually unbearable heat.

Autumn: Autumn is crisp, ripe and golden, rice is fragrant, winter wheat is sown, leaves are yellowing and falling, and frost is everywhere.

Winter: cold wind, thousands of miles of snow drifting, thousands of miles of frozen rivers up and down, only plum blossoms proud of snow.

People drink nature as a whole, the so-called unity of heaven and man. In other words, we are part of nature, so nature affects our bodies and the things around us throughout the year.

For example: generally people with a little common sense know that the best time to take tonic is in winter, the so-called winter storage in Chinese medicine, do you see someone drinking angelica ginger mutton soup in summer? Winter thickening is a manifestation of nature.

It depends on the temperature zone in which it is located, and it cannot be generalized. The four seasons of the cold and tropical zones are the same, and the temperate zone has four distinct seasons.

Most plants and animals in nature are affected by temperature, for example, peach blossoms bloom and bear fruit in spring, fruits ripen in summer, fall leaves in autumn, and do not grow in winter, while chrysanthemums bloom in autumn.

Animals such as frogs catch pests in summer and hibernate in winter, and some birds, their feathers change with the change of climate, gray in summer, white when it snows in winter, geese fly south, and fish migration are affected by the four seasons.

Seasonal transitions cover climate change, phenology.

The characteristics of change, such as the emergence of spring, the growth of summer, the harvest of autumn, and the storage of winter, mark the development process of things. In the division of the four seasons, the apparent position of the sun on the ecliptic is used as the basis, and the equinox, solstice, or four days are used as the boundary; However, the boundaries used by Eastern and Western countries to divide the seasons are not identical.

The gradual change of the seasons is not uniform across the globe in the Northern Hemisphere.

It's summer, the Southern Hemisphere.

It's winter; The Northern Hemisphere changes from warm to cold, and the Southern Hemisphere changes from cold to hot. Day and night length and sun altitude.

There are periodic changes in different seasons. When the earth is in different positions of the orbit at different times of the year, different places on the earth receive different sunlight and receive different heat from the sun.

Produce seasonal changes and differences in hot and cold. The seasons on Earth are not only periodic changes in temperature, but also in the length of day and night and the height of the sun. It influences or determines the rhythm of movement of many things in the Earth's environment.

In particular, biological adaptation is most obvious. The seasonal transition covers many characteristics such as climate change and phenological changes. The cycle of the four seasons also marks the development of things, which sprouts in spring, grows in summer, harvests in autumn, and stores in winter.

The autobiography of the earth, which leads to the cycle of day and night. When it is daytime in our country, it is night in the United States, and that is because the rotation of the earth creates different time zones. The Earth is divided into 24 time zones, with an average of 15° one time zone.

China and the United States are in different time zones, so when it is daytime in China, it is night in the United States, which is a phenomenon caused by the rotation of the earth.

The rotation of the earth leads to the alternation of the seasons. When it is summer in our country, it is also summer in the United States; When it is winter in our country, it is also winter in the United States, and in this respect, there is actually no difference between our country and the United States. This is because both our country and the United States are in the northern hemisphere.

The opposite of China's climate is generally the countries of the southern hemisphere, such as Argentina.

So why is there a cycle of spring, summer, autumn and winter, and the alternation of day and night?

The reason for the alternation of the seasons is that the Earth's axis of rotation is at an angle to its orbit. Therefore, the seasons in the Northern and Southern Hemispheres are opposite.

But the United States and China in the Northern Hemisphere have the same four seasons. Generally, June, July and August are the warmest times in the Arctic every year, and the temperature may be a few degrees below zero or even a few degrees above zero. Every year in December, January and February are the coldest times in the Arctic, with temperatures of minus tens of degrees.

The Antarctic and the North Pole are located at high latitudes and lack direct sunlight, so it is winter all year round, in fact, it cannot be completely said that there are no changes in the four seasons, but only that the changes in the four seasons are not obvious, because, regardless of summer and winter, they are both cold anyway, but the degree of cold is different. But there will be changes in polar day and polar night.

The Earth's orbit around the Sun is elliptical and has an angle to the plane of its rotation. When the earth is in different positions of the orbit at different times of the year, different places on the earth receive different solar rays and receive different heat from the sun, so there are seasonal changes and differences in cold and heat.

Climatically, the four seasons are distinguished by temperature. In the Northern Hemisphere, generally speaking, March and May are spring, June and August are summer, September and November are autumn, and December and February are winter.

In the Southern Hemisphere, the seasons are at exactly the opposite time of day in the Northern Hemisphere. When it's summer in the Southern Hemisphere, it's winter in the Northern Hemisphere; It is winter in the Southern Hemisphere and summer in the Northern Hemisphere. There are no clear boundaries between the seasons, and the transition of the seasons is gradual.

The four seasons on Earth manifest first and foremost as an astronomical phenomenon, not only periodic changes in temperature, but also in the length of day and night and the height of the sun. Of course, the length of day and night and the change in the height of the sun at noon determine the change in temperature.

The gradual change of the seasons is not uniform across the globe, with summer in the northern hemisphere and winter in the southern hemisphere; The Northern Hemisphere changes from warm to cold, and the Southern Hemisphere changes from cold to hot. The length of day and night and the height of the sun change periodically in different seasons.

The four seasons are formed by the revolution of the earth around the sun, and in our country, the closest time the earth's revolution is to the sun, summer is the opposite, and vice versa, and spring and autumn are not far away. Because the Earth is elliptical and the equator is closest to the Sun, it is the hottest all year round, and the two North and South Poles are the farthest from the Sun, and it is winter all year round.

"The earth has four seasons because there is an angle between the earth's orbit around the sun and the axis of the earth's rotation, so when the earth is in different positions on the earth's orbit, the angle of sunlight on the earth will be different, and this difference will reach the maximum when the sun is about the day, and basically in the middle when the sun is about the day. Different locations on Earth absorb different amounts of heat in the same place, thus.

This is because of the rotation of the sun.

Throughout the year, from spring to autumn, there will be many obvious changes in the world, and generally speaking, the most direct change may be the date on the calendar.

So in addition to looking at the calendar, what other changes in life reflect the changes of the seasons? The most intuitive change is the change of greenery in the natural landscape.

1. Spring goes to autumn, the four seasons change, and the intuitive change is in the green plants Generally speaking, spring goes to autumn, and the changes of the four seasons are more obvious, which lies in the natural landscape.

We should be able to observe in our lives that in spring and summer, the leaves of most plants are generally green.

And in autumn, the leaves of the green plants turn yellow. In winter, the leaves on the trees fall off, leaving only bare branches. The four seasons have the scenery of the four seasons, and there is also the beauty of the four seasons, it depends on how we appreciate it.

2. The "rain" of the four seasons also changes for the rain in spring, we have a word to describe it, "as thin as a cow's hair". In other words, the spring rain is very fine and fine, and this fine spring rain will wake up all things that have been sleeping for a winter.

We also have a word to describe the summer rain, which is "pouring rain". That is to say, in the summer, the rain is the same as soybeans, and even the same as the scoop, not as gentle as spring, but with the "heroic" of summer.

To say that the rain in autumn is not as warm as in summer, but it is not as gentle as in spring. At the same time, the weather is relatively dry in autumn, and there will be less rain than in spring and summer.

In winter, there is a special type of rain related to rain, that is, sleet, when the rain will have something like a small ice cube in it, which is also a unique winter landscape.

3. To summarize the above changes in the four seasons of the year, as well as weather changes, most of them occur in areas with distinct seasons, such as Hainan, may not be able to experience the four seasons, in Hainan, may be longer in summer, as for winter, maybe it is the same as the spring in Wuhan, which is good in Hainan and bad in Hainan. Straight to the point.

The four seasons change, some things in our lives change, pay close attention, we may be able to find a different beauty. So for the change of the seasons, what are the beautiful changes in your life?

The causes of the changes in the seasons are: the rotation of the earth, the revolution of the earth, and the tilt axis of the earth.

1. The Earth's rotation refers to the time it takes for the Earth to rotate around its axis, that is, the length of a day. The effect of the Earth's rotation is responsible for the alternation of day and night that we see.

2. The Earth's Revolution refers to the time it takes for the Earth to revolve around the Sun in an elliptical orbit, which is the length of a year. The effect of the Earth's rotation is to cause changes in the distance and angle between the Earth and the Sun.

3. The axis of inclination of the earth: The axis tilt of the earth refers to the angle of inclination between the axis of rotation of the earth and the plane of rotation of the earth. The tilt axis of the earth leads to the change of seasons.

The Earth's axis of inclination makes it possible for the Earth to receive different levels of sunlight at different times during its rotation. Relative to the orbital plane, the Earth tilts at different angles in different seasons, which leads to seasonal variations in different regions.

The revolution of the Earth is counterclockwise

From the North Star of the North Pole towards the Earth, the Earth appears to be rotating around the Sun in a counterclockwise direction. This is also why, in the Northern Hemisphere, the sun rises in the east, moves southward, and finally sets in the west, passing through the southern trajectory every day. In the Southern Hemisphere, on the contrary, the sun rises in the east, moves north of Spike, and finally sets in the west, passing through the northern trajectory every day.

The time it takes for the earth to make one revolution is about days. This is what we often call the length of a year. However, since the Earth's axis of rotation is not exactly perpendicular to the Earth's orbital plane, and there are other factors, such as tides and gravity, the Gregorian calendar year is generally defined as 365 days, with a leap year added every four years to compensate for this difference.

February in leap years has 29 days, while other years have 28 days. Therefore, there are an average of days per year, which is to keep the Gregorian calendar in good sync with the earth's orbital cycle.

The Earth and the Moon are a system of planets that revolve around the Sun.

The sun is the center of the solar system, the earth is a planet in the solar system, and the moon is a natural satellite of the earth.

In the Earth-Moon planetary system, the Moon revolves around the Earth, and the Earth rotates constantly, creating a difference between day and night.

The phases of the moon change. Since the moon itself does not emit light or is transparent, the half of the sphere facing the sun is a bright area, and the other half of the sphere is a dark area (blocked by itself) under the sun's rays. As the position of the Moon changes relative to the Earth and the Sun, the illuminated side of the Moon is sometimes facing the Earth and sometimes facing away from the Earth; Sometimes the shiny part facing the Earth is larger, sometimes it is smaller, so that different phases of the moon appear.

It can be simply summarized into two things:

1. The moon does not emit light and is opaque.

2. It is related to the relative position of the moon, earth and sun.
