Class 6 Social Science - WEST-BENGAL
Geography: Locating Places on the Earth
The chapter 'Geography: Locating Places on the Earth' introduces Class 6 students to the fundamental tools used to navigate our planet. Students learn about the shape of the Earth, the grid system formed by imaginary lines called latitudes and longitudes, and how the Prime Minister's Meridian and the Equator divide the globe. Understanding these geographical coordinates is crucial for map reading and accurately locating any place on Earth. For WBBSE board exams, this chapter forms the foundation of practical geography, frequently featuring in map-pointing, short-answer questions, and conceptual multiple-choice questions.

Globe
A true miniature model of the Earth that helps us see the correct shapes and locations of continents and oceans.
Axis
An imaginary line passing through the center of the Earth on which the planet rotates, tilted at an angle of 23½°.
Equator
The most important imaginary line running horizontally around the middle of the Earth at 0°, dividing it into the Northern and Southern Hemispheres.
Latitudes
Parallel circles running from east to west around the Earth, measured in degrees from the Equator.
Longitudes
Semi-circular lines running vertically from the North Pole to the South Pole, measured from the Prime Meridian.
Prime Meridian
The 0° longitude line passing through Greenwich, near London, which divides the Earth into the Eastern and Western Hemispheres.

Board Exam Info
In the West Bengal Board of Secondary Education (WBBSE) Class 6 Social Science annual exams, this chapter typically carries around 6 to 8 marks. Common question types include short-answer questions defining terms like Axis, Equator, and Prime Meridian, difference-based questions between latitudes and longitudes, and map-marking of important parallels like the Tropic of Cancer and Tropic of Capricorn.
Frequently Asked Questions
Why do we need imaginary lines like latitudes and longitudes?
We cannot draw actual lines on the Earth, so we use imaginary lines to create a global grid system that helps us locate any exact place on Earth easily.
What is the difference between the Equator and the Prime Meridian?
The Equator is a horizontal line at 0° latitude that divides the Earth into Northern and Southern hemispheres, while the Prime Meridian is a vertical line at 0° longitude that divides the Earth into Eastern and Western hemispheres.
Why is the Prime Meridian located in Greenwich?
By international agreement in 1884, it was decided that the longitude passing through the Royal Observatory at Greenwich, near London, would be accepted as the starting point for counting longitudes (0°).
