Questions, Activities and Projects
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.
Answer: The measured distance on the map is about 8 cm (approx.). According to the scale (2.5 cm = 500 km), the real distance is about 1600 km (approx.).
Explanation: Divide 8 by 2.5 and multiply by 500 to calculate the actual ground distance.
Q2. Why is it 5:30 pm in India when it is 12 pm or noon in London?
Answer: India follows Indian Standard Time (IST), which is 5 hours 30 minutes ahead of Greenwich Mean Time (GMT). Therefore, when it is 12 noon in London, it is 5:30 pm in India.
Explanation: Time changes according to longitude. India is east of Greenwich, so its time is ahead.
Q3. Why do we need symbols and colours in the map?
Answer: We need symbols and colours to show rivers, roads, mountains, cities and other features clearly in limited space.
Explanation: Symbols make maps simple, clear and easy to understand.
Q4. Find out what you have in the eight directions from your home or school.
Answer (Example):
- North – Market
- South – Park
- East – Temple
- West – Hospital
- North-East – School
- North-West – Bus Stand
- South-East – Playground
- South-West – Bank
Explanation: The answer will vary depending on your locality.
Q5. What is the difference between local time and standard time?
Answer: Local time is the time of a place based on its longitude and changes from place to place. Standard time is one fixed time followed by the entire country.
Explanation: India follows Indian Standard Time (IST) so that the whole country uses the same time.
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: There will be no difference in local time.
Explanation: Local time depends on longitude. Since both cities have almost the same longitude, their local time is the same.
Q7. Mark the following statements as true or false. Explain your answers briefly.
- (a) All parallels of latitude have the same length. – False
Explanation: The Equator is the longest. Other parallels become shorter towards the poles. - (b) The length of a meridian of longitude is half of that of the Equator. – True
Explanation: A meridian runs from the North Pole to the South Pole, forming half a circle. - (c) The South Pole has a latitude of 90°S. – True
Explanation: The South Pole lies at 90 degrees south latitude. - (d) In Assam, the local time and the IST are identical. – False
Explanation: Local time varies slightly, but IST is fixed for the whole country. - (e) Lines separating the time zones are identical with meridians of longitude. – False
Explanation: Time zone boundaries are adjusted to follow country borders. - (f) The Equator is also a parallel of latitude. – True
Explanation: The Equator is the main parallel at 0° latitude.
