1. Answer the following questions briefly.

(a) What are the three components of a map?

Ans. The three components of a map are – Distance, Direction & Symbol.

(b) What are the four cardinal directions?

Ans. Cardinal Directions are the most commonly used forms of direction and they are North, South, East and West. The four equal divisions – Northeast, Southeast, Southwest and Northwest – are called Primary Inter-cardinal directions.

(c) What do you mean by the term ‘the scale of the map’?

Ans. The scale of the map shows the actual distance as represented by one unit of measurement on the map. For example; if the scale of the map shows 1 cm = 10 km, this means 5 cm on the map is equal to 50 km in the real world.

(d) How are maps more helpful than a globe?

Ans. A globe can be useful when we want to study the earth as a whole. But if we want to study only a part of the earth, e.g. a continent or a country, globe is not helpful. A map is a representation or a drawing of the earth’s surface or a part of it drawn on a flat surface. It gives more information than a globe.

(e) Distinguish between a map and a plan.

Ans. A map is a visual representation of an area highlighting relationships between elements of that area such as objects, regions, and themes. Plans are a set of two-dimensional diagrams or drawings used to describe a place or an object, or to communicate building or fabrication instructions.

(f) Which map provides detailed information?

Ans. Large scale maps are the one that provide detailed information.

(g) How do symbols help in reading maps?

Ans. It is not possible to draw actual shape and size of different features (like. buildings, roads, bridges) on a map, hence they are shown by using certain standard letters, shades, colors, pictures and lines. These symbols give a lot of information in a little space. Using these symbols, maps can be drawn easily. The use of symbols makes maps simple to read.
