Introduction to CBSE Class 6 Social Science Geography Chapter "Globe: Latitudes and Longitudes"
The chapter “Globe: Latitudes and Longitudes” in CBSE Class 6 Geography explores the imaginary lines that crisscross the Earth, providing a framework for location and time. Latitudes are the horizontal lines that run from east to west and are measured in degrees north or south from the equator. The equator is the reference point, set at zero degrees latitude, dividing the Earth into the Northern and Southern Hemispheres.
Longitudes, on the other hand, are the vertical lines that run from the North Pole to the South Pole. The prime meridian, set at zero degrees longitude, passes through Greenwich, England, and divides the Earth into the Eastern and Western Hemispheres. This chapter explains how the meeting point of a latitude line with a longitude line, called coordinates, determines the exact location of a place on the globe.
The students also learn about the significance of the Tropic of Cancer, the Tropic of Capricorn, and the Arctic and Antarctic Circles. Moreover, the concept of time zones, the International Date Line, and the impact of Earth’s rotation on day and night are elucidated with clear, student-friendly language.
Assignments for CBSE Class 6 Social Science Geography Chapter “Globe: Latitudes and Longitudes”
- Map Marking: Use a globe or a map to identify and mark the equator, prime meridian, Tropic of Cancer, and Tropic of Capricorn.
- Latitude Research: Find out the latitudinal coordinates of five major world cities and describe the climate in each city.
- Longitude and Time: Explain how longitudes determine time zones by giving examples of countries with multiple time zones.
- DIY Sundial: Construct a simple sundial and use it to understand how the position of the sun changes with time.

Questions and Answers for CBSE Class 6 Social Science Geography Chapter "Globe: Latitudes and Longitudes"
- Q1: What is the purpose of latitudes and longitudes?
ANS: The purpose of latitudes and longitudes is to create a coordinate system that allows anyone to locate a place on Earth with precision. - Q2: Why is the equator considered an important latitude?
ANS: The equator is important as it is the largest circle of latitude and divides the Earth into the Northern and Southern Hemispheres. - Q3: How does the prime meridian help in determining time zones?
ANS: The prime meridian serves as the starting point for measuring time zones. Each 15-degree section of longitude to the east or west of the prime meridian represents a different time zone. - Q4: What are the Tropic of Cancer and the Tropic of Capricorn?
ANS: The Tropic of Cancer and the Tropic of Capricorn are latitudinal lines that mark the farthest points north and south, respectively, where the sun can be directly overhead. - Q5: How does the International Date Line affect the calendar date when crossed?
ANS: Crossing the International Date Line changes the calendar date by one day; if you travel eastward, you subtract a day, and if you travel westward, you add a day. - Q6: What is the significance of the Arctic and Antarctic Circles?
ANS: The Arctic and Antarctic Circles mark the boundaries within which, for at least one day each year, the sun does not set (during the summer) or does not rise (during the winter). - Q7: Why do we have time zones?
ANS: We have time zones to account for the Earth’s rotation and the resulting variation in daylight experienced at different longitudes. - Q8: What happens when you move from one longitude to another?
ANS: Moving from one longitude to another can change the local time, typically by four minutes for every degree of longitude. - Q9: What latitude and longitude coordinates are used to locate the prime meridian?
ANS: The prime meridian is located at 0 degrees longitude. - Q10: Why is a globe a better representation of the Earth than a flat map?
ANS: A globe is a better representation because it is spherical and accurately depicts the true shape, distances, directions, and relative size of the Earth’s features.
