Since the Earth is roughly spherical (shaped like a ball), you can start out in either direction from the IDL and eventually wind up in Vanuatu. The trip is much shorter, however, if you travel generally westward from the line.
Since the Earth is spherical (shaped like a ball), you can head out of Rarotonga in either direction, either east or west, and eventually wind up in Auckland. The trip is quite a bit shorter, though, if you travel westward, and that will take you across the International Date Line. At the moment of crossing the line, the right things to do are to advance your calendar by one day, and turn your clock ahead 24 hours. For example, if it happens to be 3:00 PM on Tuesday, then it becomes 3:00 PM on Wednesday when you cross the line. In reality, there's no need to make the adjustment exactly as you cross the line. Passengers typically make the change when they board the ship or plane, or when they disembark at the end of the trip. As long as you're actually at sea or in the air, it really doesn't matter much what day it is.
If you cross it going away from the US towards Japan, you're robbed of 24 hours and you don't get them at all. If you cross it going from Japan towards the US, you get to live the previous 24 hours all over again. If you cross the line twice in opposite directions, then it all cancels out. It's a lot like changing your clocks to daylight savings time and then back to standard time, only the change is 24 times as much.
The Prime Meridian based on Greenwich, England, is at 0 degrees longitude and all other meridians are "X" degrees east or west of it. The Prime Meridian was established for navigation and is the basis on which International time is kept. The International Date line is on the opposite side of the Earth from the Prime Meridian and is the point which seperates yesterday from today. The line was drawn by international agreement, and was skillfully drawn so as not to cross any land to keep all areas of a country in the same day (and time zone). There are few bends and kinks in the International Date line to achieve this, but if it was a straight line, it would generally be at 180 degrees E or W longitude. The Prime Meridian and the International Date Line are the two lines that separate the Eastern and Western Hemispheres.
The Prime Meridian- Straight line, runs through Greenwhich, England, is 0 degrees longitude, splits the world into Eastern and Western Hemispheres. The International Date Line- Much less of a Straight Line, runs through middle of the Pacific Ocean (Kind of), is where the day "switches" from one to another, but it is complicated. It's ends connect with the prime meridian, and is approximately 180 degrees in Longitude. Equator- Straight Line running "perpendicular" to Prime Meridian. 0 degrees Latitude. Splits the world into Northern and Southern Hemispheres. A couple more: Arctic Circle circles the North Pole at 66° 33' 44" North and Antarctic Circle at the same but South.
Much of England lies on the prime meridian which is 180 degrees from the international date line. Eire lies slightly to the west of the prime meridian
The International Date Line is close to the meridian of 180 degrees longitudefor much of its length, but doesn't follow it exactly, in order to avoid splittingany single island, state, or country into two different calendar dates.Helpful Spelling Glossary:-- Parallel . . . a line of constant latitude-- Meridian . . a line of constant longitude
You could do that if you want to, but it would mean that you went the long way around.It's much smarter and easier to go the short way, and notcross the Date Line.
Canada is located west of the International Date Line because the line generally follows the 180° meridian of longitude. The International Date Line was established to separate two consecutive calendar dates, and it generally runs between Russia and Alaska in the Bering Strait. Canada is located to the west of this line within the Pacific and Arctic oceans.
The measure of how much a ray of light bends when it enters the material is called the index of refraction.
There are 360 degrees. They are numbered 0, 1-179 East, 180, and 1-179 West.360 degrees.On the earth, there is the Greenwich Meridian = 0 deg;1 - 179 East and 1 - 179 West;and 180 deg, much of which forms the International Date Line.
Your boat's name is Sunday ^ Know, The Correct Answer Is... If You Cross The International Date Line You Would Advance Your Calender One Day. Thank You Ever So Much
Index of refraction
brb
This is called refraction.
Index of refraction
For a typical 6x4 line haul tractor, between 16,000 and 18,000, depending on specifics.
