Important Imaginary Lines

  • IMPORTANT IMAGINARY LINES
  • Equator: The Equator is an imaginary line on the surface of the earth midway between the poles.
  • Latitude: It is the angular distance of North and South of the Equator.
  • Longitude: Longitude of a place is its distance East or West of a fined meridian.
  • Prime Meridian: It is the 180° meridian which passes through Greenwich, a place near London It is the zero degree longitude.
  • International Date Line: It is the 180° meridian running over the Pacific Ocean, deviating at Aleutian Islands, Fiji, Samoa and Gilbert Islands.
  • Travellers crossing the Date Line from West to East (i.e., from Japan to USA) repeat a day and travelers crossing it from east to west (i.e., from USA to Japan) lose a day.
  • Parallels of Latitude: These are lies drawn on a Map or Globe showing the latitude of a place.
  • Meridians (or lines of longitude): These are lines draw on a map or globe showing the latitude of a place. These lines join the North and South poles cutting the Equator at right angles.
  • By knowing there parallels and lines we can find out the exact location of a place.
  • The poles: These are the ends of the axis of the earth. One is called the North pole and other the South pole.
  • SOLAR ECLIPSE AND LUNAR ECLIPSE
  • Solar Eclipse: It is complete or partial obscuration of the sun when the moon comes in between the sun and the earth.
  • Lunar Eclipse: It is the partial or complete obscuration of the moon’s surface when the earth comes in between the sun and the moon.
