A ship crossed the 180 ° meridian in five minutes at 10:00 on March 22, Beijing time (120 ° e, District 8 East). What's the time of the ship's position Or more than three

A ship crossed the 180 ° meridian in five minutes at 10:00 on March 22, Beijing time (120 ° e, District 8 East). What's the time of the ship's position Or more than three


If the ship crosses the 180 degree longitude eastward near the Kamchatka Peninsula or in the low latitude waters of the southern hemisphere, it is still on the west side of the date line, and the time should be 14:05 on that day; otherwise, it is 14:05 on February 21
If it is 180 degrees to the west, the date should be added by one day (23rd or 22nd)



Knowing the time zones of two places and the time of one place, how to convert the time of another place


Do you want to know the time zones of the two places and the time of one place, how to convert the time of the other place?
This simple, with two places "time zone difference" plus or minus one time is another time



Example: when Washington is in West District 5 at 6:00 on February 2, Beijing time, Washington time is: 6:00 on February 2 - (5 + 8) = 17:00 on February 1
Can you tell me the meaning of 5 + 8 in brackets


Beijing is in the East eight districts, and Washington is in the west five districts. The time zone differences should be added. If they are both in the east or west time zones, they should be subtracted



1. It is known that 125 degrees west longitude is 20:30, a certain place is 5:20, and the longitude is inversely calculated
2. It is known that the district time of 122 degrees east longitude is 18:20, and the district time of 80 degrees east longitude and the local time of 86 degrees east longitude are calculated
3. It is known that the local time of 86 degrees west longitude is 18:20, the local time of five west districts, the local time of 125 degrees west longitude and the local time of 125 degrees west longitude


If we don't emphasize that 20:20 is the local time, we will think that this time is the local time of 120 degrees west longitude



How to calculate District time, local time and urgency,
How to calculate District time, local time and urgency,
For example, it's easy to understand,


If the area time of 110 degrees west longitude is 6:05, what is the area time of 110 degrees east longitude? What is the local time? (answer analysis: premise information: a. the whole earth is divided into 24 time zones, each time zone is 15 degrees, and each degree is 4 minutes; B. the area time of West Zone 12 and east zone 12 is 15 degrees, the area time of West Zone 12 is w180 degrees - w172.5 degrees, and the area time of East zone 12 is 15 degrees



On the algorithm of geographical area time in grade one of senior high school
There is a formula that is four minutes divided by one degree


First of all, we must understand the difference between local time and district time. Only when we calculate local time, we only use the algorithm of once four minutes. When we calculate District time, we only consider the time zone. There is a trick. If the question is given local time, the general answer will also ask local time. Similarly, if the question is given district time, the answer will definitely let you ask District time
Local time formula: one degree equals 4 minutes; algorithm: East plus West minus
Area time algorithm: one hour in one time zone; algorithm: East plus West minus

I know that the latitude line spans longitude 1 degree = 111 * cos a km, where a is latitude
But the mathematics is too bad to know exactly how to calculate cos? Is there any specific value?


Just remember cos 60 = 1 / 2, because the latitude is the longest at the equator, and the others become shorter toward the poles



The great confusion of geography learning in Senior High School
Why does the Eurasian continent seem to have nothing to do with the three circle circulation?
Why does the Eurasian continent not be affected by the three circle circulation, but blow the monsoon? What about spring and autumn?
What conditions does the Eurasian continent not meet without the influence of the three circle circulation? The book says that the distribution of land and sea alternates, which only causes the pressure difference at the same latitude, which can blow the monsoon. For the equator, it is still low pressure. Why is it only three circle circulation!


One of the most important reasons for the formation of circulation is that there is geostrophic bias, which will form circulation between smaller latitudes. The Eurasian continent is the largest continent, and the Pacific Ocean is the largest ocean. The sea land relationship between the two is more obvious, which is embodied in the temperature difference caused by the specific heat difference between the land and the sea

What is the apparent motion of the sun? What do you think? There are also related questions about sunrise and sunset
2. The calculation of solar energy and building spacing, with examples


The "seeing" movement of the sun is the movement of the sun we see in our life, including the sun's Sunday seeing movement and the sun's annual seeing movement. The sun's Sunday seeing movement is that we see the sun rising and setting in the east every day, which reflects the earth's rotation from West to East
