one degree, about 111 kilometers at the equator.
The northern and southern hemispheres each have 360 degrees of longitude. The eastern and western hemispheres each have 180 degrees of longitude. You can use as many or as few 'lines' as you want, to mark off any number of degrees.
The northern and southern Hemispheres each comprise 90 degrees of latitude. On your map or globe, you're free to draw as few or as many lines as you'd like to see in that range. There is no standard set of 'lines'.
there are ninety lines in each hemisphere There are 90 degrees of latitude in the northern Hemisphere, and another 90 in the southern one. There are 180 degrees of longitude in the eastern Hemisphere, and another 180 in the western one. In each hemisphere, you're free to draw as few or as many lines in that range of numbers as you want to see. There's no standard set of 'lines' that everybody must use. Some maps and globes have more lines on them, some have fewer, some don't have any at all. Would you go into the hardware store and ask the man "How many lines are there on the tape measure ?" ?
The equator has 180 degrees in each hemisphere, dividing the Earth into the Northern and Southern Hemispheres.
The longitude of places in both the eastern and western hemispheres ranges from zero to 180 degrees. The 'lines' printed on a map or globe, and how they're numbered, are completely up to its publisher. There may even not be any lines at all on some maps or globes.
There are 90 lines of latitude in each hemisphere, ranging from 0° at the equator to 90° at the respective pole.
Each of those lines is a meridian of longitude. They are 180 degrees apart in longitude,so together they form a complete circle around the Earth. That circle is the boundarybetween the eastern and western hemispheres.
A complete globe, including Earth, always has 360 degrees. There can be an infinite number of longitudinal lines because longitudinal lines are imaginary constructs and not physical features of Earth itself, so the number of degrees between those longitudinal lines is dependent on the number of longitudinal lines, assuming the longitudinal lines are equidistant. To calculate the number of degrees between these equidistant longitudinal lines, divide 360 degrees by the number of longitudinal lines. A model globe of Earth is typically given 36 lines of longitude. Using the calculation given above, the angle between adjacent longitudinal lines is 360 degrees divided by 36 lines of longitude, or 10 degrees. If 24 lines of longitude are used to represent the 24 time zones, the angle between adjacent longitudinal lines is 360 degrees divided by 24 lines of longitude, or 15 degrees.
All the lines of longitude that meet at the poles are numbered, by degrees, minutes and seconds. Primary among these is the Prime Meridian -- 0 degrees -- and its opposite, the International Date Line -- ~180 degrees, which wanders a little for political reasons.
No, the Prime Meridian is fixed at 0 degrees longitude, running through Greenwich, London. The 180-degree meridian is the International Date Line, on the opposite side of the Earth from the Prime Meridian.
Each degree of longitude is approximately 69 miles (111 km) in length at the equator so 20 degrees is 1380 miles. The distance between lines of longitude, however, gets smaller as you move towards the poles (North or South) since all the lines converge there.
Lines of longitude are farthest apart at the equator and closest together at the poles. This is because the lines of longitude converge at the poles and spread apart at the equator due to the Earth's shape being an oblate spheroid.
