Question

differentiate between a] local and standard time b] equater and prime meridian

Answer 1

Answer:

a] The local time of a particular place refers to the time determined under the basis of the sun's apparent movement. On the other hand, the standard time refers to the fixed time of several places in a given region that fall under the same standard meridian.

b] The Equator separates the Northern and Southern Hemispheres. The Equator is at 0° latitude. The Prime Meridian separates the Eastern and Western Hemispheres.

$\huge{\sf{\boxed{\underline{(A)\:Local\:And\: Standard\:Time}}}}$

$\bold{\boxed{Local\:Time:}}$

• If we set our watches to the correct time at 12 noon when our longitude is directly under the sun, the time shown is said to be local time of a particular place.

• Eg:- If sun is over head 82°½E. longitude, all the places on that longitude will have noon at that time.

$\bold{\boxed{Standard\:Time:}}$

• Every country select a central meridian as the standard meridian.

• The local time of that standard meridian becomes the standard time for that country.

• Eg:- 82°30'E longitude is taken as the standard meridian for our country.

$\huge{\sf{\boxed{\underline{(B)\: Equator\:And\: Prime\: Meridian}}}}$

$\bold{\boxed{Equator:}}$

• The horizontal circle that goes round the earth exactly in the middle, at equal distance from the north and south poles is called the 'equator'.

• The equator divides the earth into two equal parts.

• 0° latitude is called the equator.

$\bold{\boxed{Prime\: Meridian:}}$

• Semi circle connecting north pole and south pole are called longitudes.

• 0° longitude is called the prime meridian.

• 0° longitude is called as green wich longitude or green wich meridian.

$\sf{Time\:Zones:}$

• Any of the 24 regions of the globe throughout which the same standard time is used.
