Locations in the Western Hemisphere are described with a range of 180 degrees of
"west longitude" ... exactly what you'd expect for 1/2 of a sphere. Within that range,
you're free to draw as few or as many 'lines' on your map as you feel you need.
There are 180 degrees of east longitude and 180 degrees of west longitude, for a grand total of 360 degrees of longitude around the Earth. You're free to draw as few or as many 'lines' through that range on your map or globe as you feel will make you comfortable. There is no standard set of 'lines' that everone is required to use.
There are an infinite number of lines of longitude on Earth's surface. Each line of longitude represents a meridian and measures distance east or west from the Prime Meridian, which runs through Greenwich, England.
If you have a map or globe with some longitude lines printed on it, you'll find that they stay where they are and do not move from day to day. Regardless of how many there may be on your particular map or globe, each of them has the same length ... about 12,500 miles ... and joins the north and south poles.
While longitude lines can be used to identify locations on Earth, a single line of longitude, like 15° West, passes through many countries and other geographical features. Therefore, it's impossible to pinpoint a specific country based solely on its location at 15° West longitude. If you have additional information, such as latitude or other geographical details, I might be able to help you narrow down the location.
latitude runs East to west. Longitude runs north to south. In other words, the lines of latitude are measured in degrees north and south of the equator and lines of longitude are measured in degrees east and west of the prime meridian.
There are an infinite number of lines that can be drawn on or around Earth, depending on the context or purpose. For example, latitude and longitude lines grid the Earth for navigation and mapping.
360 degrees. Longitude runs from 180 degrees East to -180 degrees West.
Latitude refers to the angular distance of a location north or south of the equator, measured in degrees. Parallels are lines of latitude that run parallel to the equator. Longitude refers to the angular distance of a location east or west of the Prime Meridian, measured in degrees. Meridians are lines of longitude that converge at the poles.
5 or 6 lines of longitude
180° of longitude are marked off east of the Prime Meridian, and another 180° west of it. You're free to draw in as many reference lines on your map as you'd like. There's no set number of lines, that you have to pick one from when you measure the longitude of a place.
Latitude and longitude are angles that describe the location of a point on the Earth's surface. Longitudes range from zero to 180 degrees east or west. Latitudes range from zero to 90 degrees north or south. There are no official 'lines'. Some maps or globes have some lines printed on them to show where a few latitudes and longitudes are, and other maps and globes have no lines at all printed on them. I have mapping software that can print 324,000 latitude lines and 648,000 longitude lines if I want them, but I have never needed them yet.
It is latitude lines. this is all from my geography class. hehehe
