180
Mainly the 180 degree line.
180 degrees east/west longitude
The 180 degree longitude is often miscalled international date line, when it is actually called the Anti Meridian.The date line is not a meridian or line of longitude because it is not a straight line as it deviates to separate geographical places, certain island groups for instance.See the link below for an image.The longitude that runs through Greenwich England is the prime meridian, which is 0 deg longitude.
The international date line roughly follows the 180° longitude line in the Pacific Ocean. When you cross this line from west to east, you advance one day, and when you cross from east to west, you go back one day.
One degree east and one degree west. You're probably looking for the prime meridian and the International Date Line, but the IDL isn't a specific line of longitude.
This imaginary line of longitude is the 180 degree line of Longitude. It is on the opposite side of the planet to the Greenwich meridian. Thus when it is 12 o'clock mid day at Greenwich, it is midnight on the 180 degree line of longitude. As you will know midnight denotes the start of a new day (and therefore a new day's date) and this is why it is called the International date line. In reality the internationally agreed path of the International date line does not follow the 180 degree longitude line. This is because if it did some pacific island countries would find themselves in two days at once (most confusing!). The line therefore jiggles about a bit as is crosses the pacific. See related link below.
It is logically the 180 degree line of longitude (halfway round the planet from the Greenwich Meridian). However, politics and pragmatism have resulted in a line that is not a line of longitude but an imaginary line (with kinks in it) called the International Date Line. The kinks exist because it would be strange for an Island Nation to have two islands in different days. Thus while the International Date Line sort of follows the 180 degree longitude line it does not do so and therefore is NOT a line of longitude.
Spain lies on zero degree longitude line together with France.
The 180 degree line of longitude is called the 180th meridian or the antimieridian. This line is 180 degrees east or west of the Prime Meridian such that longitude at 180E and 180W is the same line. The International Date Line basically follows this line from the North and South poles..
The first pair is.
The 180 degrees longitude line, also known as the International Date Line, is a navigational line used to mark the change of one calendar day to the next. It is not physically drawn on maps or globes, but rather serves as a demarcation for time differences between different regions of the world.
No, the international date line is a line of longitude, not latitude.
