FAQs on Important Questions for CBSE Class 6 Social Science The Earth Our Habitat Chapter 2 - Globe: Lattitude and Logitudes
1. Which topics from Chapter 2, Globe: Latitudes and Longitudes, are most important for the CBSE Class 6 exams for the 2025-26 session?
For the Class 6 Social Science exam, the most important topics from this chapter are the definitions and differences between latitudes and longitudes, the characteristics of the three Heat Zones (Torrid, Temperate, and Frigid), the significance of the Equator and the Prime Meridian, and the concept of calculating Longitude and Time, including Indian Standard Time (IST).
2. What is the difference between latitudes and longitudes? This is a frequently asked question.
This is a foundational question often carrying 2 to 3 marks. The key differences to mention are:
- Parallels of Latitude are imaginary horizontal circles running parallel to the Equator, measuring distance north or south of it. They are unequal in length.
- Meridians of Longitude are imaginary semi-circles running from the North Pole to the South Pole, measuring distance east or west of the Prime Meridian. They are all equal in length.
3. What kind of questions can be expected from the 'Heat Zones of the Earth' topic?
From the Heat Zones topic, you can expect different types of questions:
- 1-mark questions: Defining the Torrid, Temperate, or Frigid Zone.
- 3-mark questions: Explaining why the Torrid Zone receives maximum heat or differentiating between the two Temperate Zones.
- Map-based questions: Identifying and marking the different Heat Zones on a diagram of the Earth.
4. Why is the Equator considered a crucial reference point, and how might this concept be tested in a higher-order thinking (HOTS) question?
The Equator (0° latitude) is crucial because it divides the Earth into the Northern and Southern Hemispheres and serves as the primary baseline for all other latitudes. A HOTS question might not just ask for a definition but could ask: 'Why would life in the Frigid Zone be impossible if the Earth's axis was not tilted relative to its orbit, even with the Equator as a reference?' This tests the application of concepts rather than just memory.
5. How is time calculated using longitudes? Explain with an example suitable for a 3-mark question.
Time is calculated based on the Earth's rotation. The Earth rotates 360° in 24 hours, which means it covers 15° of longitude every hour (360/24), or 1° in 4 minutes. For a 3-mark question, an example would be: 'If it is 12:00 PM at the Prime Meridian (0°), what is the time at 30°E longitude?'
Calculation:
1. The location is 30° east, so time will be ahead.
2. For every 15° east, time is 1 hour ahead.
3. For 30° east, time will be 2 hours ahead (30/15 = 2).
4. Therefore, the time will be 2:00 PM.
6. What is the significance of Indian Standard Time (IST), and why is it an important question?
Indian Standard Time (IST) is an important topic because it applies a global concept to a national context. The question is important as it tests your understanding of why a large country needs a uniform time. IST is based on the longitude 82°30'E, which passes through Mirzapur in Uttar Pradesh. This is taken as the standard time for the whole country to avoid confusion in schedules for railways, flights, and official communications.
7. What is a common mistake students make in questions about parallels of latitude and meridians of longitude?
A very common mistake is confusing their properties. Students often forget that while all meridians of longitude are of equal length (as they all run from pole to pole), the parallels of latitude decrease in length as they move away from the Equator towards the poles. An exam question might trick you by asking if the Arctic Circle is longer than the Tropic of Cancer, and the correct answer is no.
8. What are some expected 1-mark questions from the chapter on Globe: Latitudes and Longitudes?
For the 2025-26 exams, some expected 1-mark questions are:
- What is a globe?
- What is the value of the Prime Meridian in degrees?
- Which heat zone lies between the Tropic of Cancer and the Tropic of Capricorn?
- What is the latitude of the Equator?
- What shape is the Earth? (Answer: Geoid)
