Short Questions on Accurate Maps
The reasons why maps are an essential component of learning geography are as follows—
Concept of a region:
The role of maps is most important for gaining a clear idea about a region.
Knowledge about geographical aspects:
We depend on maps in order to collect information like topography, rivers, climate, transportation, population, agriculture, industry, trade, etc of a region.
Determination of direction:
Maps are required to get an idea about the cardinal directions.
Question 2. Discuss the different types of maps.

They are as follows—
Physical maps:
Maps depicting several physical features like mountains, plains, plateaus, deserts, rivers, and natural vegetation are called physical maps.
Political maps:
Maps showing countries and states with their boundaries are called political maps.

Question 3. How is the location of any place on the globe determined?
Answer:
The location of any place on the globe determined:
The location of any place on the globe is determined by the help of parallels of latitude and meridians of longitudes.
The point of intersection between parallels and meridians is the exact location of any place.
The imaginary, circular lines running across the surface of the globe in an east-west direction are called lines of latitude. They are parallel to the Equator and to each other.
The semicircular, imaginary lines running from the North Pole to the South Pole and intersecting the Equator at right angles are called lines of longitude.
They are equal in length but hot parallel to each other. The intersection of these imaginary lines of latitude and longitude, known as the geographic grid, allows us to give a mathematical value to the location of any place on the globe.
Question 4. Write a brief note on cartography.
Answer:
Cartography:
The science and art of making maps is known as cartography. It involves the representation of political, cultural, economic and other attributes in a specific geographic area.
The technology used for cartography has been continuously changing. The first maps were hand-painted and lacked accuracy.
The advent of the compass and eventually computers have made maps more accurate and useful.
Question 5. What is the usefulness of a map?
Answer:
Usefulness of a map:
A map is an essential tool that helps us to study geography.
It is used to determine the locations of rivers, mountains and landforms in various cities, countries or continents. Maps influence all our lives.
For example, the location and extension of land boundaries, roadways, rivers, ponds, settlements, and religious establishments can be determined from a cadastral map.
The distance of a particular settlement from the roadways or railways, the nature of a settlement or a forest can also be determined by using a map.

Question 7. Which is considered to be the most recent era of map making?
Answer:
The most recent era of map making:
From cave paintings to ancient maps of Babylon, Greece and Asia, till the 21 century, people have developed and used maps for various purposes.
In the 15 century, maps were drawn on wooden or copper planks. Maps became increasingly accurate and factual during the 17,18 and 19 centuries with the application of scientific methods.
This is known as the modern era of maps. The world was poorly known until the widespread use of aerial photography following World War-1 Modern cartography is based on a combination of ground observations and remote sensing.
Question 8. Write a short note on the cadastral map.
Answer:
Cadastral map:
Cadastral maps show individual landed property or land registration, that is, the record of ownership of land.
One key feature of a cadastral map is that it carries detailed information about a particular location.
It is an official map that is generally not available for sale. A usual cadastral map in India bears a scale of 16 inches = 1 mile.
