3. For what did maps were use in ancient days?
Ans: Maps were mailny used for wars in ancient days.
4. Which are the methods of showing the elevation or height of the land?
Ans: 1. Contour line method 2. Layer tinting method 3. Digital Elevation model are the methods of showing the elevation or height of land.
5. What are contour lines?
Ans: The height of the land is measured from sea-level. Next, points of the same height are identified. Their position is marked accurately on the map.These locations are joined with a line. Such lines are called contour lines.
6. How does contour line method help us?
Ans: The contour line method helps us to understand the slope of the land and the height of different places.
7. What is Layer tinting method?
Ans: Layer tinting method is based on Contour lines. The spaces between the contour lines are filled in with colour.Each colour indicates a specific height.
8. How does information obtained in digital Elevation method?
Ans: In digital Elevation method the information obtained through man-made satellites and peesented with the help of computers.
9. What are the uses of Digital Elevation Method?
Ans; Maps made using the above methods help us ;
1. To understand the physical set-up of a region.
2. They give us an idea of its height, relief and slope.
3. We can even find the height of each point on a digital map.
10. What are the uses of physical maps?
Ans: Physical maps can be used in military operations, tourism, drawing up mountaineering routes, in making regional development plans etc.
11. What are used to make the map easy to read?
Ans; The standard signs and symbols are used to make the map read easy to read.
12. What are conventional signs?
Ans: Conventional signs are in the form of letters or geometrical shapes, for example, lines, circles, triangles, dots etc.
13. What are convetional symbols?
Ans: Conventional symbols are miniature drawings of the respective objects.
For ex. Temples, mosques, forts etc.
