Answer the following question

Question a:-What are the three components briefly. of a map?
Answer:- The three components of a map are – Distance, Direction & Symbol.

Question b:- What are the four cardinal directions?
Answer:- 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.

Question c:- What do you mean by the term ‘the scale of the map’?
Answer:- 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.

Question d:- How are maps more helpful than a globe?
Answer:- 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.:

Question e:Distinguish between a map and a plan.
Answer:– 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.

Question f:- Which map provides detailed information?
Answer:- Large scale maps are the one that provide detailed information.

Question g:- How do symbols help in reading maps?
Answer:- 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.
