Define -a) Equator b) Prime Meridian 2. Draw a diagram to show lines of longitude. 3. Name five important lines of latitude with their latitudinal value. 4. Write four differences between the lines of latitude and lines of longitude. 5. Draw a diagram to show the three heat zones (climatic zones) 6. Describe the heat zone which receives the maximum heat. 7. In Frigid zones sun does not rise much above the horizon. Sun rays are always slanting. What would be the climatic conditions there? 8. Places to which side of International date line will be ahead in time – East or West? 9. If it is 12:00 Noon at a place on Prime Meridian (0° longitude), find out the time of a place on – a) 20° E longitude b) 20° W longitude c) 15° E longitude d) 30° W longitude e) 82.5° E longitude Rules – ➢ Time of a place depends upon its meridian. ➢ Places to the East are ahead in time (difference would be added). ➢ Places to the West are behind in time (difference would be subtracted). ➢ Time taken to turn distance of 241° = 360hours = 4′ Example - Solution – 9 a) 00Given , time 12:00 noon at 0 longitude. Find out time at 20 E longitude 0Difference of longitude = 20 .0to turn 1 Earth takes 4′ 0 to turn 20 it will take 20 x 4′ = 80′ = 1 hour 20 minute As the place is in the East the difference of time will be added. 0 12:00 Noon (time at 0 )+ 1:20 (difference)01:20 PM Ans. Time at 20 Eanswer all questions​
