MAPS
- Define Intermediate directions.
Ans.- Intermediate directions
- The directions on the compass that are halfway between these cardinal points are called northeast, southeast, southwest, and northwest. These in-between points are called intermediate directions.
2. Name and explain three different types of maps.
Ans.- The three different types of maps are-
- PHYSICAL MAPS- Maps showing natural features of the earth such as mountains, plateaus, plains, rivers, oceans etc. are called physical or relief maps.
- POLITICAL MAPS-Maps showing cities, towns and villages, and different countries and states of the world with their boundaries are called political maps.
- THEMATIC MAPS- Maps showing distribution of forests, industries etc. are known as thematic maps.
3. Define the following terms: cardinal points, north line, compass
Ans.-
- Cardinal points -There are four major directions, North, South compass, East and West. They are called cardinal points.
- North line – Most maps contain an arrow marked with the letter ‘N’ at the upper right hand corner. This arrow shows the north direction. It is called the north line.
- Compass- It is an instrument used to find out main directions because its magnetic needle always points towards north-south direction.
4. Maps and globes are different from each other? Do you agree? Explain how.
Ans.-
- A globe is a three-dimensional sphere while a map is two-dimensional.
- The globe represents the whole earth, whereas a map may represent the whole earth or just a part of it.
- A globe can be used to get a broad-level picture of the world while maps provide more specific information about different places.
5. What are Conventional Symbols? How are they useful to us?
Ans.- Conventional symbols – Conventional symbols are the symbols that are widely accepted interpretations of signs and symbols. There is an international agreement regarding the use of these symbols on maps due to which they are called conventional symbols.
They useful to us in many ways-
- It is not possible to draw on a map the actual shape and size of different features such as buildings, roads, bridges, trees, railway lines or a well. So, they are shown by using certain letters, shades, colours, pictures and lines.
- These symbols give a lot of information in a limited space. With the use of these symbols, maps can be drawn easily and are simple to read.
- Even if you don’t know the language of an area and therefore cannot ask someone for directions, you can collect information from maps with the help of these symbols.
- Thus you can say maps have a universal language that can be understood by all.
6. What is the purpose of a scale on maps? How does it help us to measure distance? Explain with the help of an example.
Ans.-
- When we need to represent a large ground distance on a small size paper we use a scale.
- Scale is the ratio between the actual distance on the ground and the distance shown on the map.
- For example, the distance between your school and your home is 10 km. If you show this 10 km. distance by 2 cm on a map, it means, 1 cm on the map will show 5 km. on the ground.
- The scale of your drawing will be 1cm = 5 km. Thus, scale is very important in any map.
- If you know the scale, you will be able to calculate the distance between any two places on a map.
