Q1. Answer the following questions in about 30 words:
(i) Which are the two natural points of reference on the earth?
North Pole and South Pole are the two natural points of references on the earth.
(ii) What is a great circle? What are coordinates?
Equator is also called a great circle. The line drawn midway between the North Pole and the South Pole is called the equator. It is the largest circle and divides the globe into two equal halves.
(iii) Why does the sun appear to be moving from east to west?
The latitudes and longitudes are commonly referred to as geographical coordinates as they provide systematic network of lines upon which the position of various surface features of the earth, can be represented.
(iv) What is meant by local time?
The earth rotates from west to east and therefore, the sun appears to be moving from west to east.
Q2. Distinguish between latitudes and longitudes.
| Longitude | Latitude |
|---|---|
| The meridians of longitude refer to the angular distance, in degrees, minutes, and seconds, of a point east or west of the Prime (Greenwich) Meridian. | The parallels of latitude refer to the angular distance, in degrees, minutes and seconds of a point north or south of the Equator. |
| Lines of longitude are often referred to as meridians. | Lines of latitude are often referred to as parallels. |
| 0° longitude is called prime meridian. | 0° latitude is called equator. |
| It divides the earth into eastern hemisphere and western hemisphere. | It divides the earth into northern hemisphere and southern hemisphere. |
| These are 360 in number: 180 in the eastern hemisphere and 180 in the western hemisphere. | These are 180 in number: 90 in southern hemisphere and 90 in northern hemisphere. |
