Best Answer

The IDL should nominally follow the meridian of longitude that is 180 degrees from the Greenwich

Prime Meridian ... roughly down the middle of the Pacific Ocean. But in defining the line, it was

zigged and zagged where necessary to avoid cutting across nations and politically contiguous

island groups.

What ocean does the international dateline pass?

The International Date Line passes through the Pacific Ocean. It is an imaginary line that runs from the North Pole to the South Pole, mostly along the 180° longitude line.


What does the international dateline follow?

The International Dateline roughly follows the line of longitude that is both 180° E longitude and 180° W longitude, which passes through the western Pacific Ocean. The Dateline is shifted east or west in several locations to maintain a common date for associated countries or regions (Russia, US, New Zealand).


Is the international dateline the Eastern boundary of East longitude?

No. It would be the western boundary.East longitude is measured starting from the Prime Meridian and increasing eastward.It reaches the maximum of 180° east in the vicinity of the International Date Line.


When a hurricane crosses the International Dateline what is it reclassified as?

After crossing the International Date Line, a hurricane is not reclassified. Its name and classification remain the same based on the original data recorded before crossing the Dateline.


What is the meridian that forms m ost of the international dateline?

The International Date Line (IDL) is roughly along 180° longitude, with diversions to pass around some territories and island groups.


A merididian of longitude is an imanginary line that runs from the Internatonal date line to the?

Any merididian of longitude is an imanginary line between the north pole and the south pole. There is one for every possible longitude, and the International Dateline roughly but not exactly follows the one marked 180°, through the Pacific Ocean.


Is the prime meridian the international dateline?

No, the prime meridian and the International Date Line are two different imaginary lines on Earth. The prime meridian is the line of longitude at 0 degrees, dividing the Earth into Eastern and Western Hemispheres. The International Date Line, on the other hand, runs mostly along the 180th meridian and marks the change of one calendar day to the next.


What is the line of latitude 180 degrees north south and is used to standardize international dates?

You're getting at the International Dateline. It roughly follows the line of longitude at 180 degrees east/west, and really has little to do with standardized international dates, whatever those are.


What continent is on the east of the international dateline?

North America is on the east of the International Dateline.


How does the international dateline work?

The International Date Line is an imaginary line of longitude of 180 degrees around the Earth. It works when a person crosses the line from the east to the west a day is added. The opposite effect happens when crossing from west to the east with a day subtracted.
