  1. 1. GlobeBy Kavita Grover1Presentation for grades IV & V
  2. 2. What is a globe ?A globe : Is a model of the earth Gives an accurate pictureof the earth’s surface Shows the location ofplaces on the a smallerscale2Presentation for grades IV & V
  3. 3. Earth’s surface71% of earth’s surface iscovered by water.Large water bodies arecalled oceans.There are five oceans:IndianPacificAtlanticArcticSouthern29 % of the earth’ssurface is land.Large land masses arecalled continents.There are sevencontinents:AsiaAfricaNorth AmericaSouth AmericaEuropeAustraliaAntarctica3Presentation for grades IV & V
  4. 4. Features of the earthThe northernmost point of the earth iscalled the North PoleThe southernmost point of the earth iscalled the South PoleAn imaginary line running through thecentre of the earth and joining the northand south pole is called the Axis ofRotation4Presentation for grades IV & V
  5. 5. Features of the earth An imaginary line runningthrough the centre of theearth and dividing it into twoequal parts is called theEquator. The area north of theequator is called theNorthern Hemisphere The area south of theequator is called theSouthern Hemisphere5Presentation for grades IV & V
  6. 6. Longitudes and Latitudes Imaginary lines run fromthe North Pole to theSouth Pole. These arecalled Longitudes.Imaginary lines runparallel to the equatorand are called Latitudes.6Presentation for grades IV & V
  7. 7. Important Latitudes Arctic Circle at 66.5degree north Tropic of Cancer at 23.5degrees north Equator at 0 degree Tropic of Capricorn at23.5 degrees south Antarctic Circle at 66.5degree south7Presentation for grades IV & V
  8. 8. Presentation for grades IV & V 8LongitudesImaginary lines run fromthe North Pole to theSouth Pole. These arecalled Longitudes orMeridiansThe imaginary line thatdivides the earth into twoequal halves- East andthe West is called thePrime MeridianThe prime meridianpasses throughGreenwich and is calledthe Greenwich Meridian
  9. 9. RotationThe earth spins onits axis from west toeast causing dayand night.9Presentation for grades IV & V
  10. 10. Earth GridThe latitudes and the longitudes form a grid or anetwork on the earth’s surface called the earth grid10Presentation for grades IV & V
  11. 11. Earth Grid Locating places withthe help of the earth grid:11Presentation for grades IV & V
  12. 12. Locating places using the grid. Delhi is located at 28.38 N and 77.12 E. 28.38 N means 28.38 degrees latitude, northto the equator, and 21.42 E means 21.42 degrees longitude, eastto the prime meridian. Locate the latitude and the longitude on themargins of the map, and draw line extendingfrom these points. The point where these two lines meet on thegrid gives us the location of Delhi.Presentation for grades IV & V 12
