Answers
Answer:
(a) What are the three components of a map?
✍️There are three Components of Maps – distance, direction and symbol. Maps are drawings, which reduce the entire world or a part of it to fit on a sheet of paper.
️️
(b) What are the four cardinal directions?
✍️North, east, south, and west are the four cardinal directions, often marked by the initials N, E, S, and W. East and west are at right angles to north and south.

(c) What do you mean by the term 'the scale of the map"?
✍️Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground.

(d) How are maps more helpful than a globe?
✍️A map is a representation or a drawing of the earth’s surface or a part of it drawn on a flat surface according to a scale. It is impossible to flatten a round shape and scale it. Therefore, maps are more helpful than a globe.
