Which is the Standard Meridian of India?
Answers
Answer:
(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:
A great circle,also known as an orthodrome,of a sphere is the intersection of sphere and a plane that passes through the center point of the sphere.
the longitude lines converge at the poles, the distance between two meridians is different at every parallel. ... The latitude lines are concentric circles that become smaller near the poles. They form a single point at the poles where the meridians begin
