Differentiate between a) Local and Standard time b) Equator and Prime meridian.

Answer»

a) Difference between Local and Standard time :

Local Time	Standard Time
1) The time of a place when the mid day sun is over head is called local time.	1) The local time of the standard meridian of a country is called a standard time.
2) It changes from place to place.	2) It remains same for that particular country.
3) The place on the same longitude has the same local time.	3) The place on the same longitude has the different standard time.

Example: If the 1ST is 12.00 noon, the local of Mumbai is 39 minutes – 1ST = 11.21 minutes a.m.

Since Mumbai is on 72°82′ east longitudes, it is 9°45′ behind the 82°30′. Thus the local time of Mumbai is 9.45 x 4 = 38 minutes.

b) Differences between Equator and Prime meridian :

Equator	Prime meridian
1) Equator is 0° latitude.	1) Prime meridian is 0° longitude.
2) Equator divides the earth into parts, i.e. Northern hemisphere and Southern hemisphere.	2) The Prime meridian divides the earth into two equal parts i.e., Eastern hemisphere and the Western hemisphere.
3) Equator is a circle.	3) Prime meridian is a semi-circle.
4) It is an imaginary line that runs east and west around the exact middle of the globe. (A horizontal line)	4) It is an imaginary line running from pole to pole and passing through Greenwich, England. (A vertical line)
