(6) What would be the latitude of a place on the South Pole?
90° S
90° N
0°
Ans: 90° S
(B) Read the following statements and correct the wrong ones.
(1) While describing the location of a place mentioning the meridian is sufficient.
Ans: Wrong
Correct statement: While describing the location of a place mentioning the meridian as well as parallels is essential.
(2) For describing the extent of a region, it is necessary to assume the latitude and longitude of the centre of the adjoining region.
Ans: Wrong
Correct statement: For describing the extent of a region. It is necessary to assume two latitudes and two longitudes at the extreme ends of the same region.
(3) Location of a road can be described only with a map.
Ans: Wrong.
Correct statement: Location of a road can be described by a map as well as by GIS, GPS, etc.
(4) 0° East meridian and 180° East meridian.
Ans: Wrong
Correct statement: 0° Meridian and 180° Meridian.
(5) The extent of a road or a river course is described with the help of the latitude of a point in the source and the longitude of a point at the end.
Ans: Wrong
Correct statement: The extent of a road or a river course is described with the help of the latitude of a point as well as longitude of a point in the source and the longitude of a point as well as latitude of a point at the end.
(6) 8° 4′ N parallel to 37° 66° N parallel is the correct description of a location.
Ans: Wrong
Correct statement: 8°4′ N parallel to 37°66′ N parallel is the incomplete description of a location as it expresses only a latitudinal spread of a location.
