Lines of longitude measure how far something is east or west of the Prime Meridian.
The lines that measure east and west on the globe are called longitude lines or meridians. The prime meridian, located at 0 degrees, divides the Earth into Eastern and Western Hemispheres. Longitude lines run vertically from the North Pole to the South Pole.
The lines on a globe refer to latitude and longitude lines that help locate points on Earth's surface. Latitude lines run east-west and measure a point's distance north or south of the equator, while longitude lines run north-south and measure a point's distance east or west of the Prime Meridian. These lines intersect at specific points to create a grid system used for navigation and mapping.
90 degrees north latitude and 90 degrees south latitude are the maximum values; they represent the exact locations of the pole. Zero degrees is the equator. 180 degrees longitude is the exact limit of longitude; it represents the originally defined location of the International Date Line, exactly opposite the Prime Meridian. Oh. On second reading (and some editing of the question) I finally grasped the question. Latitude: the equator is one. Then there is one to eighty nine in the north, and again in the south. 90 degrees north and south are points, not lines. That makes 179 lines of latitude. Then you have the Prime Meridian (one); and 179 degrees east, and again west. That's 359. Then there is 180 degrees which makes 360 lines of longitude. 179 plus 360 equals 539 lines total.
Looking at a sphere, the Earth, from the side, i.e. - the equator, eliminating each 'pole' position, which would appear as 'points', as opposed to 'lines', lines drawn at one degree intervals from top (North) to bottom (South), would number 178; given that there are 180 degrees from North to South.
Scientists use latitude and longitude lines to divide the Earth into sections. These lines create a grid system that helps pinpoint specific locations on the Earth's surface.
They measure latitude & Longitude.
lines of longitude are lines drawn north and south and measure east and west a famous line of longitude is the Prime meridian
Longitude lines measure how far (in degrees) you are East or West of the Prime Meridian (which is a longitude line that runs through Greenwich, England and is designated as 0° longitude).
Longitude lines.
west and east
East-West
Prime Meridian.
Longitude is the correct answer
Longitude
Latitude lines run parallel to the equator and measure a location's distance north or south of the equator, while longitude lines run perpendicular to the equator and measure a location's distance east or west of the prime meridian. Latitude lines are represented by horizontal lines on maps, while longitude lines are represented by vertical lines.
east and west
Lines of longitude are also known as meridians. They run north-south and measure east-west.
