Question 1.
Draw a simple map of a school’s playground. Let us assume it is a rectangle, 40 m in length and 30 m in width. Draw it precisely with your ruler on a scale of 1cm=10m.
Answer:
The playground is drawn to scale, with 1 cm representing 10 m , and the dimensions are labelled clearly. It provides a better visualisation of the playground’s layout and features.
Question 2.
Now measure the diagonal of the rectangle. How many centimetres do you get? Using the scale, calculate the real length of the playground’s diagonal, in metres. (Page 10)
Answer:
The diagonal of the rectangle is 5 cms.
So if 1 cm as per scale equals 10 metres,
Then 5 cms × 10 metres = 50 metres
The real length of the playground’s diagonal is 50 metres.

Question 1.
Return to the two friends sitting in Gujarat and Assam. Use this example to explain the difference between local time and standard time.
Answer:
One of the two friends is sitting in Porbandar (Gujarat) and the other in Tinsukia (Assam).
There is a difference in local time between both the two cities. Local time is the time based on the position of the Sun at a specific longitude or place. For example, since Assam is in the East of Gujarat, the Sun rises and sets earlier in Assam as compared to Gujarat.
Standard time on the other hand, is the official time set for a region or country, used to maintain. uniformity. It is based on the standard meridian of the country. In India, both Gujarat and Assam follow Indian Standard Time (IST), which is the same across the country.

Question 1.
Returning to page 10 and to Fig. 5.2 in Chapter 5 of this textbook, taking the scale to be 2.5 cm = 500 km , calculate the real distance from the estuary of the Narmada River to the estuary of the Ganga River. (Hint: round off your measurement on the map to an easy number.)
Answer:
1,000 km
Question 2.
Why is it 5: 30 pm in India when it is 12 pm or noon in London?
Answer:
It is 5:30 pm in India when it is 12 pm or noon in London because of the following reasons:
London is located at 0 degree longitude while the time of 82 1/2 degree E longitude is taken as Standard Time in India.
There is a difference of 82 1/2 degree between the longitude of London and the Standard Meridian of India (82 1/2 degree E).
Time in India is ahead of London. It is 4 minutes ahead at every longitude towards the East.
Hence, time in India is ahead of London by 5:30 hours (4 × 82 1/2 = 330 minutes or 5:30 hours).
Question 3.
Why do we need symbols and colours in the map?
Answer:
Symbols and colours are important component of maps and are needed in maps because:
- It is not possible to draw actual shape and size of different features say like buildings, roads, temples, rivers, mountains etc. due to lack of space, so we use various symbols and colours to show these features.
- In this way numerous details and more information can be shown in limited space.
- Symbols and colours enable easy understanding of maps by a variety of users.
- They help tide over language barriers as maps have a universal language. These are called conventional symbols.
- The Survey of India, a government body, has fixed a set of symbols and colours for maps of India.
Question 4.

Question 5.

Answer:

Question 6.
Delhi’s and Bengaluru’s latitudes are 29° N and 13° N; their longitudes are almost the same, 77° E. How much will be the difference in local time between the two cities?
Answer:
Delhi and Bengaluru have nearly the same longitude, so the difference in local time is based on their latitude.
Latitude difference: 29° N (Delhi) -13° N (Bengaluru) = 16°
Time difference: Each degree of latitude difference equals 4 minutes of time.
16 degree x 4 minutes = 64 minutes
So, Delhi and Bengaluru have a local time difference of about 64 minutes.
Question 7.
Mark the following statements as true or false; explain your answers with a sentence or two.
1. All parallels of latitude have the same length.
Answer:
False. They are not of the same length. The length of a degree of latitude varies depending on the distance from the equator.
2. The length of a meridian of longitude is half of that of the Equator.
Answer:
False. All meridians are of equal length. The meridians cut the equator at a right angle and are all in the same length unlike parallels.
3. The South Pole has a latitude of 90°S.
Answer:
True. This is because the distance from the equator to the either pole is one-fourth of a circle around the Earth, which is 90°
4. In Assam, the local time and the IST are identical.
Answer:
False. Assam officially follows IST, its local solar time would be about 30 minutes ahead of IST.
5. Lines separating the time zones are identical with meridians of longitude.
Answer:
True. Time zones are generally based on the meridians of longitudes, with each time zone spanning 15° of longitude.
