Answer

There are several merits of using a representative fraction as a scale in a map. Some of them are:

1. It provides a simple and direct way to express the relationship between the map and the ground.

Answer the following questions

Question 7 (a)

What are maps ? How are they useful?

Answer

Maps are a graphical representation of the earth’s surface, showing geographical features, cities, and towns, among other things. They are useful for navigation, planning, understanding the physical and cultural landscape of an area, and studying the natural and human-made features of the earth’s surface.

Question 7 (b)

Write about any 2 types of maps.

Answer

1. Topographical Maps: These maps are also known as contour maps, as they show the three-dimensional structure of the Earth’s surface, such as mountains, valleys, rivers, and other physical features. They are usually drawn to a large scale, which means that they cover a relatively small area but provide a lot of detail about that area.
2. Political Maps: These maps show the boundaries and locations of countries, states, and cities, as well as major bodies of water and other physical features. They are designed to give a clear picture of the world or a particular region and are often used in conjunction with other types of maps, such as topographical maps or thematic maps. Political maps can be drawn to different scales, depending on the purpose for which they are intended.

Question 7 (c)

What languages does a map usually have ?

Answer

The languages of a map include distance, direction, colours, symbols, signs, and other features that help us read and understand the map correctly. These languages give us a clear idea about the particular region shown on the map.

Question 7 (d)

What are small scale maps ?

Answer

Small scale maps are maps with a relatively small representative fraction, typically smaller than 1:100,000. These maps cover a large area but lack detail, making them useful for getting a general idea of an area’s features and layout.

Question 7 (e)

What are large scale maps?

Answer

Large scale maps are maps that show a relatively small geographic area in great detail, such as a neighbourhood, city block, or building interior. They typically have a high level of accuracy and detail, and are used for specific purposes like urban planning, engineering projects, and land surveys.

Question 7 (f)

What are the different types of scales ?

Answer

There are three types of scales used on maps: verbal, graphic, and representative fraction.

1. Verbal scale: It is a description of distance using words. For example, “1 inch equals 1 mile.”
2. Graphic scale: It is a bar line marked to show distance on the map. It is often divided into miles, kilometers, or other units of measurement.
3. Representative fraction: It is a ratio that compares the distance on the map to the actual distance on the ground. For example, “1:50,000” means that one unit on the map represents 50,000 units on the ground.

Question 7 (g)

How is scale useful ? What are the uses of scale ?

Answer

Scale is an essential component of a map as it provides a ratio between the distance on the map and the actual distance on the ground. It helps in measuring the distance between two points accurately and determining the actual size of the area. The scale is used for planning, designing, and executing various development projects, such as roadways, railways, and water supply systems. It is also used for military planning, navigation, and tourism.

Question 9 (a)

Discuss about the different types of maps.

Answer

Maps can be classified into different types based on their purpose, content, and scale. Here are some of the common types of maps:

1. Physical maps: These maps show the physical features of the earth’s surface, such as mountains, rivers, valleys, and deserts. Physical maps are designed to depict the natural landscape of the earth and are usually represented in different colors to show the different elevations.
2. Political maps: These maps show the political boundaries of countries, states, and regions. They also show the locations of cities, towns, and other man-made features like roads, highways, and railways.
3. Topographical maps: Topographical maps are designed to show the detailed features of the earth’s surface, such as contours, landforms, and elevations. They are usually large scale maps and are used by geologists, hikers, and other outdoor enthusiasts.
4. Thematic maps: Thematic maps are designed to show a particular theme or topic, such as population density, weather patterns, or vegetation cover. These maps are useful for analyzing data and trends in a specific area.
5. Navigational maps: Navigational maps are used by sailors and pilots to navigate their way around the world. They show the locations of navigational hazards, such as rocks, reefs, and shoals, as well as the locations of ports, harbors, and other important landmarks.
6. Road maps: Road maps are designed to show the network of roads and highways in a particular area. They are useful for planning road trips and for finding directions to a particular destination.
7. Cadastral maps: Cadastral maps are used to show the boundaries of properties, such as fields, gardens, and buildings. They are usually large-scale maps and are used by land surveyors, engineers, and architects.

Question 9 (b)

What are the uses of a map? Describe.

Answer

The uses a map are

1. Maps help in locating places accurately.
2. Maps provide information about the physical features of an area, such as mountains, rivers, and forests.
3. Maps can show political boundaries and the distribution of population and resources.
4. Maps are useful for planning and navigation.
5. Maps can help in understanding and analyzing data related to various topics, such as climate, geology, and demographics.
6. Maps are used for disaster management and emergency response.
7. Maps are used in education for teaching geography and history.

Question 9 (c)

What is scale? What are the different methods used for expressing scale?

Answer

Scale is the ratio between the distance on a map and the corresponding distance on the Earth’s surface. It helps to represent the Earth’s surface accurately on a flat map. The different methods used for expressing scale are:

1. Statement of Scale: A statement of scale provides a written description of the scale such as “1 cm on the map represents 1 km on the ground”.
2. Representative Fraction (RF): RF is a ratio that compares the distance on the map to the distance on the ground. For example, a map with an RF of 1:50,000 means that one unit on the map represents 50,000 units on the ground.
3. Graphic Scale: A graphic scale is a bar line that is divided into sections to represent units of measurement. The scale can be used to determine the actual distance between two points on a map.
