Explain the following terms
Question 1
Map
Answer
Map — A map is a representation of the Earth, or a portion of the earth drawn to scale on a flat surface.
Question 2
Cardinal points
Answer
Cardinal points — There are four directions, North, South, West and East; and they are called as the cardinal points.
Question 3
Scale
Answer
Scale — Scale can be defined as a ratio between a distance measured on a map and a corresponding distance on land, connecting the two points represented by the same unit.
Question 4
Legend
Answer
Legend — A list of conventional signs and symbols used in every map is called a legend.
Question 5
Magnetic compass
Answer
Magnetic compass — A Magnetic compass is a device that shows the cardinal directions used for navigation and geographic orientation. It is also called Mariner's compass as it is mostly used by sailors.
Question 6
Globe
Answer
Globe — A model of the earth, representing the three-dimensional spherical shape of the earth in miniature form. It is not drawn to scale.
Give reasons
Question 1
A map is more accurate than a globe.
Answer
A map is more accurate than a globe because it is drawn to the scale on a flat surface and thus provides more precise information as compared to the globe.
Question 2
A verbal scale is not as popular as a linear scale.
Answer
A verbal scale is expressed in words, e.g. 1 cm on map represents 50 km on the ground. It is not popular as it does not provide accurate measurement. A linear scale represents the relationship between a particular distance on the map and the actual distance on the Earth. It is drawn according to the statement in such a way that the distance can be calculated most accurately on the map.
Question 3
Pole star is useful in finding directions.
Answer
Pole star is useful in finding directions because it always points towards North and is always visible in the sky.
Differentiate between
Question 1
A map, sketch and plan
Answer
| Sl. No. | Map | Sketch | Plan |
|---|---|---|---|
| 1. | Map shows a comparatively larger area. | Sketch gives an idea of a location with the help of rough drawing. | Plan shows a building or a small area. |
| 2. | Maps can be drawn on a large scale as well as small scale. | Sketch is not drawn to scale. | Plan shows very small area on large scale. e.g., 1 cm = 1 m. |
| 3. | Maps serve the purpose of finding location of a country, distance, direction and distribution of crops, etc. | Sketch may not show all details. | Plan serves only a limited purpose regarding the plan of a colony, or township or a house. |
Question 2
large scale and small scale maps
Answer
| Sl. No. | Large scale maps | Small scale maps |
|---|---|---|
| 1. | Large scale maps show a small area in great details. | Small scale maps show a larger area in less detail and space. |
| 2. | Large scale map is of two types: cadastral maps and topographical maps. | Small scale map is of two types: Wall maps and Atlas maps. |
Question 3
Tributaries and distributaries
Answer
| Sl. No. | Tributaries | Distributaries |
|---|---|---|
| 1. | A tributary is a stream or river that flows into a larger stream. | A distributary is the stream that branches off from the main stream and flows away. |
| 2. | Found in the middle course of a river. | Found in the lower course of a river in river deltas. |
Question 4
Meander and delta
Answer
| Sl. No. | Meander | Delta |
|---|---|---|
| 1. | S-shaped loops or curves formed by the river in the plains are called Meanders. | Triangular area that blocks the path of the river towards its end is called delta. |
| 2. | Meander is formed by the irregular land that forces the river to swing from side to side. | It is formed by the deposition of the alluvium brought by the river. |
| 3. | Formed in the middle course of the river. | Formed in the lower course of the river. |
Question 5
Anticline and syncline
Answer
| Sl. No. | Anticlines | Synclines |
|---|---|---|
| 1. | The arched or upraised parts of the folds are known as anticlines. | A downward fold or an inverted anticline is called syncline. |
| 2. | Anticline is an arch like fold. | Syncline is a trough of stratified rock. |
Answer in brief
Question 1
Why is map more useful than a globe? Give two reasons.
Answer
Map is more useful than a globe because:
- A map is more accurate than a globe and provides more precise information as maps are drawn to scale whereas a globe is not drawn to scale.
- A globe represents the relative shapes and sizes of the continents, countries and oceans of the entire earth in 3D whereas maps can be of different types like Large Scale maps, Small scale maps, Physical Maps, Political Maps, Thematic maps, etc. helping us to accurately find location of a country, distance, direction and distribution of crops, etc.
Question 2
Why is a verbal scale not accurate?
Answer
Verbal scale is not accurate as it becomes invalid if the size of the map is increased or decreased. It cannot be converted into different units.
Question 3
What is meant by R.F. : 1:50,000?
Answer
The meaning of R.F. : 1:50,000, is that 1 cm on the map represents 50,000 cm on the ground.
Question 4
What are the advantages of drawing a map to scale?
Answer
Following are the advantages of drawing a map to scale:
- We can easily find out the exact distance between two places.
- Area of a place can be calculated with accuracy.
Question 5
Identify and draw the given figure and label it.
Answer
The given figure shows meander of a river. The labelled diagram of meander is provided below:
Question 6
What is the significance of colours in map reading?
Answer
The colours in the map help us to identify the features of that place easily. As these colours are universally accepted, hence they do not cause any confusion to the map reader. For example, blue colour is used to show water bodies, red colour is used to denote settlements and so on.
Question 7
Name the intermediate directions.
Answer
The intermediate directions are:
- North-West (NW)
- North-East (NE)
- South-West (SW)
- South-East (SE)
Question 8
State any two ways to measure distances.
Answer
Two ways to measure distance are:
- Verbal scale or a statement
- Representative Fraction or R.F.
Question 9
What is the significance of symbols in maps?
Answer
Symbols are conventional and universally accepted. They are used to depict large number of features on a small map. They make it easy for the reader to read the map. Symbols are used for natural as well as man-made features and cultural features.
Question 10
What do you mean by origin of a river?
