The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian ... It is common to both east longitude and west longitude.
It runs through the Pacific Ocean, and was the nominal guideline for the position of the International Dateline, although the dateline itself had to depart from the antimeridian in several places.
Allof the lines are calle longitude. Bit the middle one would be the Prime Meridian, as the Equator is the middle like for lattitude.
Well, this is a very close estimate so I would say about 42 degrees East to about 47 degrees East.
There is no fixed set of meridians. A meridian is just an imaginary line that takesshape when you choose any longitude and mark a little dot at every point onEarth with that same longitude.If you were to begin at any longitude, travel straight east or west all the wayaround the Earth until you arrived back at your starting point, and make a markin your notebook every time you cover an interval of 5 degrees of longitude, thenyou would wind up with 360/5 = 72 marks in your notebook.
hemispheres and deg (degrees) are not compatible. solid angles are measured in steradians of spheres 2pi steradians or 0.5 spheres in a hemisphere In cartography, a hemisphere would encompass 180 degrees of longitude.
Hours are not units of distance measurement. Minutes and seconds are, but it depends on where it is measured. If measuring degrees of longitude along the equator, each degree is about 60 miles, so one minute (1/60th degree) would be 1 mile. Degrees of longitude differ along different lines of latitude (different Earth's circumference). Degrees of latitude, however, are a constant distance (about 69 miles).
The prime Meridian is 0 degrees longitude.
The prime meridian is at 0 degrees longitude. Therefore, any longitude close to the prime meridian would be a value close to 0 degrees, such as 1 degree or -1 degree longitude.
The line of longitude for a place that is halfway between the prime meridian and the 80th line of longitude and west of the prime meridian would be -40 degrees longitude. The prime meridian is at 0 degrees, and halfway between 0 and 80 is 40 degrees. Since the location is west of the prime meridian, the longitude would be measured as negative.
90 degrees
Assuming that "all the way west of the Prime Meridian" would be on the opposite side of the globe from the prime meridian, or at 180o, "halfway west of the Prime Meridian" would be the 90oW meridian.
The prime meridian is located at 0 degrees longitude.
90 degrees west longitude
The name of 0 degrees longitude on a map is the Prime Meridian. It is the starting point for measuring longitude, dividing the Earth into the Eastern and Western Hemispheres.
90 degrees 40 degrees and 90 degrees
That would be zero degrees longitude.
90 degrees west
90 degrees west
