Read the following para and answer the questions.
The point, Line, Area: We use symbols to show any physical object on the map.
If we are asked to show Delhi in India map, we will mark a point 
and label it j as Delhi, To show the river Godavari, we draw a line 
along its course, for the Railway line we will draw a track line 
to represent it. In the Andhra Pradesh map, if we want to show the area of Krishna or Guntur district, we demarcate its boundary and mark it with some color or pattern, which is known as a real symbol. Thus all physical objects are shown on the map with the help of a point, line, or area symbol.

All places on this line will have the same heights of 50 meters. Contour lines will be in irregular shape depending upon the landform. These cannot cut with each other. The distance between two contour lines will depend upon the landscape. If the land has a steep climb, then the contour lines will be near to each other. If the slope of the land is gentle, then the contour lines will be quite far from each other.

Question 14.
How can we represent the heights of land on flat paper?
Answer:
Drawing of Nimpur Village:
In Atlas, we can find some maps called ‘Physical Maps’. In these maps, we will find different types of land colored in green, yellow or brown. Actually, they show the variety of landforms and depict the heights of places. Here the height of the hills hides what is behind them. A map has to show all places without hiding them. One way in which we can show heights on maps is through the use of color.
