Question 12

Question 3: Towards which direction is the flat land located in the map?

Accepted Answer

The flat land is located towards the east.

Question 13

Question 4: What are the maximum and minimum values of the lines in the map?

Accepted Answer

The maximum value of the lines in the map is 800 & minimum value is 600.

Question 14

Question 5: What do these values indicate?

Accepted Answer

These lines indicate the altitude of the region from the sea level.

Question 15

Question 6: Do you find any similarities in the map and the model in fig. (a)? What are those?

Accepted Answer

The model in figure (a) & the contour line map in figure (b) are of the same region. The values of latitudes & longitudes are same on both the maps.

Question 16

Question 7: Which figure give us more information and what is that information?

Accepted Answer

Fig. (b) Contour line map gives more information. It gives us information about the altitude of the landforms slope of the land forms with latitudes & longitudes

Question 17

Question 8: Is there any similarity between this map and the sketch map of the potato hill?

Accepted Answer

Yes, similar to the sketch map of the potato hill, the contour line map too is a 3D figure (Model of earth’s surface) which has been converted into a 2D map. The Contour line map is depicting contour line intervals.

Question 18

Question 1: Contour lines join places with the same on a map.

Accepted Answer

altitude

Question 19

Question 2: Generally, contour lines do not _______ each other.

Accepted Answer

cross.

Question 20

Question 1: How are contour maps helpful to us?

Accepted Answer

(i) Contour maps help us to understand various facets of landforms, like altitude, relief, slope, direction of slope and the drainage. (ii) These maps are of immense use to mountaineers, trekkers, soldiers, defence officers, etc. (iii) These maps prove to be of great use in planning of a region.

Question 21

Question 2: Contour lines generally do not cross each other. Give reason.

Accepted Answer

(i) Contour lines join places with the same altitude on a map. (ii) Therefore they generally do not cross each other.
