Class 6 Social Science Chapter 1, “Locating Places on the Earth”, helps students understand how we find different places on our planet. The Earth is very big, so to locate any country, city, or ocean correctly, we use special tools like maps, globes, latitudes, and longitudes. This chapter builds a strong foundation for geography. By understanding globes, maps, latitudes, and longitudes, students can easily locate places anywhere in the world. Practising map work regularly will make this topic simple and interesting.

Questions, Activities and Projects(Class 6 SST Chapter 1 Question With Answer)

Q1. 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.)

Given:
Scale on the map = 2.5 cm = 500 km

Map distance (approx.) = 4 cm

2.5 cm = 500 km
1 cm = 200 km

So,
4 cm = 4 × 200 = 800 km

Answer:
The real distance between the estuary of the Narmada River and the estuary of the Ganga River is approximately 800 kilometres.

Q2. Why is it 5:30 pm in India when it is 12 pm or noon in
London?

Answer:
India is located to the east of the Prime Meridian, while London lies on the Prime Meridian.
Indian Standard Time is 5 hours and 30 minutes ahead of Greenwich Mean Time.
Therefore, when it is 12 noon in London, it is 5:30 pm in India.

Q3. Why do we need symbols and colours in the map?

Answer:
Maps have limited space, so it is not possible to draw real pictures of every feature.
Symbols and colours are used to represent different features like rivers, roads, buildings, and forests.
They make maps easy to read and understand.

Q4. Find out what you have in the eight directions from your
home or school.

Answer:
North – Main road
South – Playground
East – Market
West – Temple
North-East – Hospital
North-West – Park
South-East – Bus stand
South-West – Residential area

Q5. What is the difference between local time and standard time? Discuss it in groups, with each group writing an answer in 100 to 150 words. Compare the answers.

Answer:
Local time is the time of a place based on its longitude and the position of the Sun.
Different places have different local times because the Earth rotates.

Standard time is the uniform time followed by the whole country.
It is based on a selected longitude.
India follows Indian Standard Time (IST), which is based on 82½°E longitude.

Q6. 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:
Local time depends on longitude.
Delhi and Bengaluru lie on almost the same longitude (77°E).
Therefore, there is no difference in local time between the two cities.

Q7. Mark the following statements as true or false; explain
Your answers with a sentence or two.
–>All parallels of latitude have the same length.
–> The length of a meridian of longitude is half of that of
the Equator.
–> The South Pole has a latitude of 90°S.
–> In Assam, the local time and the IST are identical.
–> Lines separating the time zones are identical with
meridians of longitude.
–> The Equator is also a parallel of latitude.

All parallels of latitude have the same length.
False – Only the Equator is the longest.
The length of a meridian of longitude is half of that of the Equator.
True – A meridian is a half circle from pole to pole.
The South Pole has a latitude of 90°S.
True – The South Pole lies at 90° South.
In Assam, the local time and the IST are identical.
False – Local time differs, but the whole country follows IST.
Lines separating the time zones are identical to meridians of longitude.
False – They are adjusted to follow country borders.
The Equator is also a parallel of latitude.
True – It is the largest parallel.
