Question

Tick the correct answer :
The total number of longitude are ___
A)360
B)180
C)90
D) None of these

Answer 1

Hint:The Earth is spherical in shape because of which it is difficult to describe a position on it relative to other positions. To make things easier, a network of imaginary lines are drawn on the globe from east to west and north to south . Horizontal and parallel imaginary lines that go from east to west are called latitudes. Vertical lines going north to south are called longitudes.

Complete Answer:Lines that run pole to pole are called longitudes. Also known as Meridian, these lines of longitude cross the equator at right angles. The lines of longitude get narrower as they move away from the equator, as they are widest apart in the equators , and reach zero at the pole as all the lines of longitudes converge at the poles.

There are 360 degrees of longitude and the longitude line of 0 degree is known as Prime Meridian which passes through Greenwich in England. On one side of the Prime Meridian is the Eastern Hemisphere and on the other is the Western Hemisphere. The longitude of a place is its angular distance east or west of the Prime Meridian.

Therefore the correct answer is option (A )-360.

Note:Unlike the parallels of latitude which are full circles and not of same length, longitudes are semi circles and of same lengths. One should also keep in mind that the total number of latitude is 180.
