What is the time of sunrise each day? When is sunrise

Different places and different times.

Every day is different.

1. In local time, the sun "rises in the east and sets in the west" as the standard, and in the same latitude, the adjacent location to the east will see the sun before the location to the west.

It's early. Students should pay attention to three points: (1) The concept of local time - the clock and clock time that varies according to longitude are called local time. （2）

At the same moment, different times around the world with different longitudes are different. (3) According to the difference between the local time of the two places, the longitude difference between the two places is converted.

Local time and calculation.

1) The understanding of graticule: longitude, longitude and the division standard of the eastern and western hemispheres; Latitude, latitude and northern and southern hemispheres, middle and low high latitudes, five belts.

Criteria for the division of the country. The length of the longitude of 1° latitude is 111 km, and the length of the latitude of 1° is 111·cos km ( is the local latitude.

degrees). 2) The concept of local time: the moment that varies according to longitude (at the same time on the same line). Time calculations are essentially local time calculations.

3) The nature of local time:

Determine the time of this meridian in strict accordance with the relationship between a meridian and the sun's illumination, such as 12 noon and 0 midnight;

In strict accordance with the "east morning and west evening, east plus west minus, after calculation, every second must be calculated" for time conversion;

Because local time is always for a certain meridian, there is no flat two-dimensional space (region), and there is a variability between east and west, so it often causes time.

It brings a lot of inconvenience to traffic and communication.

4) Calculation of local time: clear spatial positioning and geographical analysis in place and accurate mathematical calculation.

Spatial positioning: the longitude of the two points is used to clearly and accurately reflect the spatial relationship;

Geographical analysis: the relationship between the known, the unknown and the east-west, the conversion of longitude difference and time difference;

Mathematical calculations: Calculate carefully and check carefully.

Calculation formula: the local time sought = known local time + - longitude difference) 150

Winter solstice: Sunrise: 07:30, Sunset: 16:30, Summer Solstice: Sunrise: 4:30, Sunset: 19:30;

Spring and autumn equinox days: Sunrise: 6:00, Sunset: 18:00.

Sunrise**. The time of sunrise varies depending on the season and the latitude of each place. Traditionally, the winter solstice is believed to be the latest in the Northern Hemisphere, but in fact the latest sunrise is in early January.

By the same token, the earliest time of sunrise is not on the summer solstice, but in mid-June. Even in the equatorial region, the sunrise and sunset times change slightly throughout the year.

Extended: The time of sunrise and sunset: in the summer half of the year, the sunrise is before 6 o'clock, and the sunset is after 18 o'clock; In winter, the sun rises after 6 o'clock and sets before 6 p.m. Spring and autumn equinox, sunrise at 6 o'clock, sunset at 6 o'clock.

Brother Fang Qi's pants at sunrise and sunset: In addition to the polar day and polar night, when the sun shines directly in the northern hemisphere, the sunrise in the northeast and the sunset in the northwest are everywhere. When the sun shines directly in the southern hemisphere, the sunrise in the southeast and the sunset in the southwest are. Spring and autumn are equinoxes, rising in the east and falling in the west.

Sunset**. Sunrise time 12 days long; Sunset time is 12 days long.

On the contrary, the length of the day and the length of the night can be calculated according to the sunrise and sunset time of a certain day, and the method is: the length of the day in a certain place, the sunset time, the sunrise time (12 noon sunrise time) 2 (the sunset time 12 noon) 2. The length of the night somewhere (24 o'clock at midnight and sunset time) 2 (at 0 o'clock at midnight at sunrise) 2.

Sunrise is the summer half of the year, sunrise before 6 o'clock, sunset after 18 o'clock; In winter, the sun rises after 6 o'clock and sets before 6 p.m. Spring and autumn equinox, sunrise at 6 o'clock, sunset at 6 o'clock.

Orientation of sunrise and sunset: except for the polar day.

Outside the polar night, when the sun shines directly in the northern hemisphere, the sun rises in the northeast and sets in the northwest. When the sun shines directly on the point.

In the southern hemisphere it is, around the sunrise southeast, sunset southwest. Spring and autumn are equinoxes, rising in the east and falling in the west.

Sunrise time. 12 days long; Sunset time is 12 days long.

On the contrary, the length of the day and the length of the night can be calculated according to the sunrise and sunset time of a certain day in a certain place, and the method is as follows:

Day length at a certain place Sunset time Sunrise time (12 noon sunrise time) 2 (Sunset time 12 noon) 2.

Somewhere the night is long (midnight.

24 o'clock (sunset time) 2 (sunrise time 0:00 midnight) 2.

Generally speaking, the sunrise time is not earlier than 4:40 at the earliest, and no more than 7:40 at the latest, if it is Xinjiang, it should be calculated according to their time, which is two hours slower than Beijing, for example, Beijing is 10:27, and Xinjiang is 8:27

The time of sunrise varies with the season and the latitude of each place, which is uncertain. According to Beijing time, the sunrise time in China.

Mostly at 5 to 7 points. In addition, the latest time for sunrise is early January, and the earliest time for sunrise is in mid-June. The sunrise on the winter solstice is at 07:30, and the summer solstice.

The sunrise is at 4:30 and the sunrise on the spring and autumn equinoxes is at 6:00.

The time of sunrise varies with the season and the latitude of each place, which is uncertain. According to Beijing time, the sunrise time in China is mostly at 5 7 o'clock. In addition, the latest time for sunrise is early January, and the earliest time for sunrise is in mid-June.

The sunrise is at 07:30 on the winter solstice, 4:30 on the summer solstice, and 6:00 on the spring and autumn equinoxes.

Sunrise is between half past four and half past six。Sunrise is the fourth hour of the 12 o'clock in the day, which refers to 4:30 to 6:30 in the morning, and the earthly branch is named after the hour. The time of sunrise varies depending on the season and the latitude of each place.

Traditionally considered in the Northern Hemisphere.

The winter solstice is the latest time to sunrise, but in fact the latest time to sunrise is in early January.

Difference Between Sunset and Sunrise

Sunrise refers to the sun's first rise over the horizon.

Or the appearance of the sun as first seen. Generally refers to the time when the sun rises slowly over the horizon in the east, but it is indeed defined as the moment when the sun surface just rises above the horizon, rather than the entire sun surface leaving the horizon. Sunset is an important dividing point between the earth's ecological environment cycle and biological activities.

There is an ancient agricultural proverb that says, "The sunrise is good and pure, and the sunset is resting."

When the sun sets over the horizon, the flow of molecules in the air decreases, the temperature begins to decrease, and most animals become less active and enter a state of rest. At the same time, the plant stops photosynthesis.

Consumes oxygen from the outside of the base of the socks. Sunset marks the beginning of the night and is the end of a day's work life.
