Latitude and Longitude | Gk about latitude and longitude

4. LATITUDE AND LONGITUDE

Latitude is a Geographic co-ordination that specifies the north-south position of a point on the Earth’s surface. Latitude is the angle which ranges from 0⁰ at the Equator to 90⁰ (North or South) at the Poles.

1. What is Latitude?  :  - Imaginary Lines.
2. Measurement of Latitude is done by     : - Degree, Minute and Second.
3. How much length is there in each 1 Degree? : -       111 K.M
4. Total Latitude lines: 180 (North Pole: 90 and South Pole: 90).
5. Tropic of Cancer is 23 ½ ^{0 North} Latitude.
6. Tropic of Capricorn is 23 ½ degree South Latitude.
7. 66 ½ degree North Latitude is called Artic Circle
8. 66 ½ degree South Latitude is called Antarctic Circle.
9. 0 degree Latitude = Equator Line.

1. What is Longitude? : - Imaginary Lines.
2. In each 1degree Longitude, what is the time difference? : - 4min.
3. In 15 degree longitude, what is the time difference? : - 1 Hr.
4. Longitude is also called Meridian of Longitudes.
5. Longitude is measure is Degree, Minutes and Seconds.  60 second equals to one minute and one minute equals to? : - 1 Degree
