Question

How do the meridians of longitude help us in understanding the time differences of different places?​

Answer 1

geographic) meridian (or line of longitude) is the half of an imaginary great circle on the Earth's surface, terminated by the North Pole and the South Pole, connecting points of equal longitude, as measured in angular degrees east or west of the Prime Meridian.[1] The position of a point along the meridian is given by that longitude and its latitude, measured in angular degrees north or south of the Equator. Each meridian is perpendicular to all circles of latitude. Each is also the same length, being half of a great circle on the Earth's surface and therefore measuring 20,003.93 km (12,429.9 miles).

Answer 2

How do the meridians of longitude help us in understanding the time differences of different places?​

• It is also 360 degrees (Being a circle) so divide 360 by 24 =15 This is the number of degrees of change in the suns position every hr of the day.
• So if your longitude was say 120 degrees then you could divide that by 15 and you would have 8.
• This represents the difference in time between GMT and your position.
