Answer:
1) The 5 pieces of information that are commonly found in the map margin are as follows-
(a) Map scale- It is one of the important feature that helps in understanding the size of the area on earth. It is generally the ratio between the distance between any two places on the map and the distance on the actual ground. For example, 1:50,000 which means that 1 inch on the map is equivalent to 500 km on the ground surface.
(b) North direction- The north direction is mentioned in the extreme right top or left downside of the map. It points the proper direction that is essential for navigation purposes.
(c) Legends- It is one of the most essential information, as it is a box that contains various symbols of different colors and each symbol describes place or location.
(d) Bar scales- It is usually mentioned at the center of the lower marginal side of the map and is a ruler that converts the distance on the map to the distance on the ground.
(e) Lines of latitudes and longitudes- The latitudes and longitudes are the lines that are often highlighted on the map, extending both in the North-south direction and East-West direction respectively. The equator, tropics and the Arctic circles are represented with a dark line.
2) The latitudes are the lines that are all parallel to one another, extending from 0° at the equator to 90° in both the hemisphere i.e to the poles. They originate from the eastern to the western side.
3) The contour lines are the lines of equal elevations. In a topographic map, the contour intervals are the fixed intervals of height that are taken between two contour lines.
4) When the contour lines are closely spaced then it indicates a steeper slope but when they are broadly spaced then it depicts a gentle or shallow slope.
