Questions and Answers

What is the main purpose of latitude and longitude measurements?

  • To chart weather patterns across different regions
  • To identify the exact position of a place on Earth (correct)
  • To measure the distance between two points
  • To determine the height above sea level of a location
  • Which statement accurately describes the equator?

  • It represents the maximum longitude of 180°.
  • It marks the boundary between eastern and western hemispheres.
  • It is the furthest point north at 90° latitude.
  • It divides the Earth into northern and southern hemispheres and is at 0° latitude. (correct)
  • How are area references constructed on a map?

  • By combining the easting and northing at the lower left corner of the square. (correct)
  • By using compass directions to navigate to the coordinates.
  • By identifying the central point of the grid square.
  • By writing the northing before the easting.
  • What do the terms 'eastings' and 'northings' refer to?

    Study Notes

    Latitude & Longitude

    • Locations on Earth are defined by latitude and longitude, measured in degrees (°).
    • Latitude indicates distance north or south from the equator, with the equator at 0° latitude.
    • Latitude ranges from 0° at the equator to 90° at the poles (90° N at the North Pole, 90° S at the South Pole).
    • Longitude indicates distance east or west from the prime meridian in Greenwich, England, also at 0° longitude.
    • Longitude ranges from 0° to 180° east and west of the prime meridian.

    Area & Grid Reference

    • Eastings are horizontal numbers on a map, increasing towards the east, while northings are vertical numbers, increasing towards the north.
    • To find an area reference (AR), write the easting and northing of the lower left corner of a square on the grid, always in the order of easting before northing.
    • Area references consist of four digits, formatted as two-digit eastings followed by two-digit northings.
    • For precise location identification, grid references are used, dividing eastings and northings into tenths.
    • The grid reference combines the three-digit easting with the three-digit northing to form a six-digit reference for a specific point, enhancing map communication and usability.

    Relief

    • Relief measures the difference in elevation between the highest and lowest points in a landscape, typically noted in meters (m) or feet (ft).
    • Common geographical features include mountains (high elevation), valleys, plains, and plateaus (generally lower elevation).
    • Landscapes with greater elevation variation are described as high relief, while those with minimal variation are low relief.
    • Topographical maps illustrate relief through spot heights (exact elevations) and contour lines (illustrating elevation changes).
    • Spot heights mark specific heights above sea level, while contour lines depict the land's shape, with numbers indicating elevation.
    • Relief can be calculated by subtracting the lowest elevation point from the highest elevation point in the area.

    Scale

    • Maps are a scaled-down representation of geographic areas, aiding in spatial understanding and navigation.
