B. Read The Following Statements And Correct The Wrong Ones:

Question 1. While describing the location of a place mentioning the meridian is sufficient.
Answer: While describing the location of a place, we need to consider one parallel and one meridian.
In simple words: To pinpoint a location accurately, you need both its latitude (parallel) and longitude (meridian), not just one.

🎯 Exam Tip: Emphasize that both latitude and longitude are essential coordinates for precise location identification on Earth.

Question 2. For describing the extent of a region, it is necessary to assume the latitude and longitude of the centre of the adjoining region.
Answer: For describing the extent of a region, we need to consider two parallels and two meridians at the extreme ends of the same regions.
In simple words: To describe how far a region stretches, you need to state its northernmost and southernmost latitudes, and its easternmost and westernmost longitudes.

🎯 Exam Tip: When describing the extent of an area, always refer to the range of latitudes and longitudes that cover its boundaries.

Question 3. Location of a road can be described only with a map.
Answer: Location of a road can be described with latitude and longitude of a point.

🎯 Exam Tip: Understand that geographical coordinates provide a universal way to describe any location, even linear features like roads, by marking points on them.

Question 4. 0° East meridian and 180° East meridian.
Answer: 0° meridian and 180° meridian.
In simple words: There's no such thing as an "East" meridian for 0° and 180°; they are the Prime Meridian (0°) and the International Date Line (180°) which divide East and West.

🎯 Exam Tip: Recall that 0° longitude is the Prime Meridian and 180° longitude is roughly the International Date Line, serving as universal reference points without an East/West label for themselves.

Question 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.
Answer: The extent of a road or a river course is described with the help of the latitude and the longitude of a point in the source and also at the end.
In simple words: To fully describe a road or river, you need both the latitude and longitude for its starting point (source) and its ending point.

🎯 Exam Tip: Remember that linear features require two sets of coordinates (start and end) to define their geographical spread completely.

Question 6. 8° 4' N parallel to 37° 66' N parallel is the correct description of a location
Answer: 8° 4' N parallel to 37° 66' N parallel is the correct description of a location.
