Que: What are cardinal points and intermediate directions?

Ans: The four major directions - North, South, East and West are called cardinal points. Beside these major directions we have intermediate directions - North - East (NE), South - East (SE), south - West (SW) and North - West (NW). The intermediate directions are very helpful in locating any placce more accurately.

Que: Write a note on 'compass'.

Ans: The direction of a place is traced out with the help of a compass. It is an instrument Used to find our main directions. It magnetic needle always points towards north - south direction.

Que: Define and discuss 'distance' as a component of a map.

Ans: Maps are drawing. They reduce the whole world or a part of it to fit on a sheet of paper. In other words we ca say that maps are drawn to reduced scales. but it needs great care while doing this reduction work in order to keep the distance between the real places. It can be possible when a small distance on paper represents a large distance on the ground. For this purpose a scale is used.

Scale is the between the actual distance on the ground and the distance shown on the map. We can understand this with the help of an example. Suppose, the distance between your coaching centre and your school is 8km. If you show this 8km distance by 2cm on a map. It means, 1cm on the map will show 4km on the ground. Thus, the scale of your drawing will be 1cm = 4km scale is very important in any map.

If scale is known, calculation of distance between anyb two places on a map will be easy. A small scale is used to show large areas on a paper like continents or countries. For example, 10cm on the map shows 1000km of the ground. A large scale is used to show a small area like a village or town on paper. For example, 10cm on the map shows 1000 metres only on the ground.

Que:  GIve an account of 'direction' as a major component of a map?

Ans: Direction is an important component of a map. Most maps contain an arrow marked with the letter 'N' at the upper right hand comer. This arrow show the north direction. It is called the north line. After knowing the north direction, other directions, east, west and south can be easily found out.

There are four major directions - North, South, East and West. They are called cardinal points. Besides these, there are four intermediate directions. They are north - east (NE), south - east (SE), south - west (SW) and north - west (NW). Location of any place with more accuracy can be possible with the help of these intermediate directions.

Que: Discuss symbols as a major component of a map.

Ans: Drawing different features such as building, roads, etc. in their actual shape and size on a map is perhaps not possible, it is therefore, they are shown by using certain letters, shapes, colours, pictures and lines. These are symblos that give a lot of information is a limited space.

With the use of these symbols, maps can be drawn easily and are simple to read. These symbols help us greatly in a situation when don't know the language of an area and therefore cannot ask someone for directions. We can collect information from maps with thw help of these symblos.

Maps have a universal language known and understood by all. There is an international agreement regrading the use of these symbols, which are known as conventional symbols.
