Q19. Distinguish between a map and a plan.
between a map and a plan
map is a representation or a drawing of the earth’s surface or a part of it
drawn on a flat surface according to a scale.
plan is a drawing of a small area on a large scale.
Q20. What is a sketch map?
sketch is a drawing mainly based on memory and spot observation and not to
scale. Sometimes a rough drawing is required of an area to tell where a
particular place is located with respect to other places. Such
a rough drawing is drawn without scale, and is called a sketch map.
Q21. How do symbols help in reading maps?
Symbols give a lot of information in a limited space. With the use of these
symbols, maps can be drawn easily and are simple to read. Even if we don’t know
the language of an area and therefore cannot ask someone for directions, we can
collect information from maps with the help of these symbols. Maps have a
universal language that can be understood by all.
Q22. Differentiate between small scale map and large scale map.
Difference between small scale map and large scale map
small scale map
large scale map
When large areas like continents or countries are to be shown on a paper,
then we use a small scale. For
5 cm. on the map shows 500 km. of the ground. It is called a small scale map.
When a small area like village or town is to be shown on paper, then we use a
large scale that is 5 cm.
on the map shows 500 metres only on the ground. It is called a large scale
Q23. Explain the major components of maps.
are three Components of Maps – distance, direction and symbol.
Maps are drawn to reduced scales. But this reduction is done very carefully so
that the distance between the places is real. Therefore, a scale
is chosen for this purpose. When large areas like continents or
countries are to be shown on a paper, then we use a small scale. When
a small area like village or town is to be shown on paper, then we use a large
Most maps contain an arrow marked with the letter ‘N’ at the upper right hand
corner. This arrow shows the north direction. It is called the north line. When
we know the north, we can find out other directions, for example east, west and
It is not possible to draw on a map the actual shape and size of different
features such as buildings, roads, bridges, trees, railway lines or a well. So,
they are shown by using certain letters, shades, colours, pictures and lines. These
symbols give a lot of information in a limited space. With the use of these
symbols, maps can be drawn easily and are simple to read.
Q24. Draw different symbols used in a map.
