1 INDIAN SCHOOL MUSCAT MIDDLE SECTION DEPARTMENT OF SOCIAL SCIENCE The Globe Latitudes and Longitudes NAME: CLASS VI SEC: ROLL NO: DATE: I NAME THE FOLLOWING: 1. A small spherical model of the Earth: 2. It is 0 0 latitude and is a great circle: 3. The hottest zone: 4. The zone between Tropic of Cancer and Arctic Circle in the north and Tropic of Capricorn and Antarctic Circle in the south: 5. The zone between Arctic Circle and N Frigid zone and Antarctic Circle and S Frigid zone: 6. Lines of latitude and longitude form a network of lines: 7. It helps us to determine the time at a place: 8. The standard meridian for India: 9. The time followed all over India : 10. The time difference between Greenwich Mean Time(GMT) and Indian Standard Time(IST): II FILL IN THE BLANKS: 1. The earth is spherical in shape, slightly flattened at the and bulging at the 2. The shape of the earth is best described by the term which means earthshaped. 3. The earth rotates on its axis from to 4. The northern end of the axis is the and the southern end, the 5. The horizontal lines (east-west lines) are called 6. The is a great circle. 7. The vertical lines (north-south lines) are called

2 8. There are lines of latitude in the northern hemisphere as well as in the southern hemisphere. 9. On the basis of the distance from the equator, the earth is divided into the following zones. 10. There are a total of lines of longitude. 11. All lines of longitude converge or meet at the two 12. The is the shortest route between two places on the earth. 13. The world is divided into zones. III STATE WHETHER THE STATEMENTS ARE TRUE OR FALSE: 1. We write E or W with longitude: 2. A great circle divides the earth into two halves: 3. The earth rotates in an anti-clockwise direction: 4. The axis of the earth is tilted at an angle of 23 ½ 0 to the vertical: 5. A country cannot have more than one standard time: IV MATCH THE FOLLOWING: S.No. Column A S.No. Column B Responses 1. Vertical rays of the sun a Southern Hemisphere Slanting rays of the sun b Northern Hemisphere Tropic of Cancer c Equator South Frigid d Important latitude Antarctic Circle e Poles Arctic Circle f Heat zone 6. V OBSERVE THE DIAGRAM AND LABEL IT: A B A C. C D. E.

3 VI ANSWER THE FOLLOWING QUESTIONS IN ONE POINT EACH : 1. Define Axis. 2. What are parallels? 3. Why the heating does becomes less as we move from equator to the poles? 4. What are meridians? 5. What is the International Date Line? 6. Why are shipping and airline routes plotted along great circle? VII ANSWER THE FOLLOWING QUESTIONS IN TWO POINTS EACH : 7. What do you mean by latitude? 8. What do you understand by longitudes? 9. What is the importance of longitudes? 10. Distinguish between local time and standard time. VIII ANSWER THE FOLLOWING QUESTIONS IN FOUR POINTS EACH : 11. Explain how time and date change when one crosses the International Date Line. 12. How is local time determined? IX.A ON THE OUTLINE MAP OF THE WORLD MARK 0 0 LATITUDE AND 0 0 LONGITUDE: X CALCULATE THE TIME OF THE FOLLOWING PLACES USING LONGITUDES: 1) What is the time in Muscat (60 0 E), when it is 12 Noon in London? 2) What is the time in Bridge town (60 0 W), when it is 12 Noon in London? 3) What is the time in Chicago (90 0 W), when it is 12 Noon in London? 4) What is the time in Shanghai (120 0 E), when it is 12 Noon in London?

4 XI. IN THE OUTLINE MAP OF INDIA MARK AND LABEL 82½ 0 E LONGITUDE AND 23 ½ 0 N LATITUDE: SOME GEOGRAPHICAL FACTS The location of a place in relation to another place or nearby land marks is Relative Location. The location of a place using the coordinate system formed by Latitudes and Longitudes is Absolute Location GMT is now officially known as UTC- Universal Time Coordinate As the Earth Moves from west to East, the Places which are to the East of India are ahead of India Time and the places which are to the West of India are behind India Time. The shadow of an object will be shortest at Noon and longest at Sunrise or Sunset

5 INDIAN SCHOOL MUSCAT MIDDLE SECTION DEPARTMENT OF SOCIAL SCIENCE The Globe Latitudes and Longitudes TASK SHEET- 10 M NAME: CLASS VI SEC: ROLL NO: DATE: I FILL IN THE BLANKS: (½ x 10 = 5marks) 1. Lines of Latitude run (horizontally/vertically) 2. Lines of Longitude run (vertically/horizontally) 3. The country which has highest number of time zones is (Russia/USA) 4. Lines of Latitude locate places North or South of the 5. The Prime Meridian is degree Longitude. 6. Lines of Longitude locate places East or West of the 7. It is drawn approximately along the Meridian: 8. The axis is tilted at an angle of to the vertical 9. The lines of Latitude and Longitude combine to make a 10. The time difference between Greenwich Mean Time(GMT) and Indian Standard Time(IST): II ANSWER THE FOLLOWING QUSTIONS AS DIRECTED: 1. Distinguish between local time and standard time. (2marks) LOCAL TIME STANDARD TIME

6 2. Why does the heating becomes less as we move from the equator to the poles? (1mark) IIIOBSERVE THE GIVEN PICTURE AND ANSWER THE FOLLOWING QUESTIONS: (½ + ½ + 1) a) The heat zone that lies between North Pole and Antarctic Circle and between South Pole and Arctic Circle is b) The heat zone that lies between Tropic of Cancer and Tropic of Capricorn is c) Colour the Heat Zones

7 INDIAN SCHOOL MUSCAT MIDDLE SECTION DEPARTMENT OF SOCIAL SCIENCE The Globe Latitudes and Longitudes TASK SHEET- 10 M NAME: CLASS VI SEC: ROLL NO: DATE: I FILL IN THE BLANKS: (½ x 10 = 5marks) 1. Lines of Latitude run horizontally(horizontally/vertically) 2. Lines of Longitude run verticallty(vertically/horizontally) 3. The country which has highest number of time zones is Russia (Russia/USA) 4. Lines of Latitude locate places North or South of the Equator 5. The Prime Meridian is 0 degree Longitude. 6. Lines of Longitude locate places East or West of the Prime Meridian 7. It is drawn approximately along the Meridian: International Date Line 8. The axis is tilted at an angle of 23 ½ 0 to the vertical 9. The lines of Latitude and Longitude combine to make a grid. 10. The time difference between Greenwich Mean Time(GMT) and Indian Standard Time(IST): 5½ hours II ANSWER THE FOLLOWING QUSTIONS AS DIRECTED: 1. Why the heating does becomes less as we move from equator to the poles? (1mark) As we move from equator to the poles the rays of the sun become increasingly slanting and therefore heating becomes less. 2. Distinguish between local time and standard time.(2marks) Each longitude has its own time which is called the local time of that longitude The middle/central longitude of each time zone is taken as the standard meridian and the local time on that meridian is generally followed all over as the standard meridian

8 III OBSERVE THE GIVEN PICTURE AND ANSWER THE FOLLOWING QUESTIONS: (½ + ½ + 1) d) The heat zone that lies between North Pole and Antarctic Circle and between South Pole and Arctic Circle is FRIGID ZONE e) The heat zone that lies between Tropic of Cancer and Tropic of Capricorn is TORRID/TROPICAL ZONE f) Colour the Heat Zones SOME GEOGRAPHICAL FACTS: The location of a place in relation to another place or nearby land marks is Relative Location. The location of a place using the coordinate system formed by Latitudes and Longitudes is Absolute Location GMT is now officially known as UTC- Universal Time Coordinate As the Earth Moves from west to East, the Places which are to the East of India are ahead of India Time and the places which are to the West of India are behind India Time.
