4). SKETCH - is a rough freehand drawing based on one’s observation and memory.

5). PLAN - is a detailed drawing of a small area on a large scale.

6). SCALE -Can be defined as the ratio between the distance on a map and the actual distance on the ground.

 For e.g. the distance between your home and the market is 10 km. This distance can be shown on the map in 2cm. Thus the scale for this map will be 1cm: 5km. It means that 1 cm on the map represents 5 km on the ground.

7.) LEGEND - Features on a map are depicted using certain colors, symbols or letters. The component of a map which explains the colors, symbols or letters is called legend or key.

8.)  TITLE - is the component of map which states the kind of information provided in the map. For e.g. if the title of the map is India- Political, it will show boundaries of the States and their capitals.

Q.3. Question answers:-

A.    What does globe represent? ( Or Advantages of globe) ?

Ans:

·        The globe is a small-scale three dimensional model (exact representation) of the earth.

·        The lines of latitude and longitude drawn on the globe helps us to understand the location of the hemispheres.

·        It accurately shows us the shape of the continents and water bodies.

·        The different physical features and location of places are also marked on the globe.

B.    Why do we need maps?( Or Disadvantages of globe)

Ans:  Globe is bulky and cannot be stored easily. It cannot show details of landforms and locations of small towns. It does not provide detailed information about climate, vegetation, agriculture, etc. Larger globes are difficult to handle and carry around. Therefore maps are used.
