What is the black horizontal line made between 98 and 99 northings called?
Show Hint
Solution and Explanation
In topographic maps, grid lines are used to mark specific coordinates on the map. Vertical lines represent eastings (east-west direction), and horizontal lines represent northings (north-south direction). The black horizontal line between 98 and 99 northings indicates a specific latitude on the map.
Step 2: Role of Northings.
The northing lines represent the distance north of the equator, and they help map users navigate the map by providing a way to measure position in the north-south direction. The line between 98 and 99 northings would represent a specific area that lies between these two latitudes.
