    Study Notes

    Geographic Grid: Latitudes and Longitudes

    • Lines of latitude are imaginary lines parallel to the Equator.
    • Lines of longitude run north-south, passing through the poles.
    • The intersection of latitude and longitude lines defines a location on Earth.
    • Latitude measures angular distance north or south of the Equator.
    • Latitude is measured in degrees, with the Equator being 0 degrees.
    • Latitude is calculated based on the angle a location makes with the Earth's center.
    • Parallels of latitude are full circles, except for the Equator, which is considered a Great Circle.
    • There are 181 parallels of latitude at 1° intervals.
    • Key latitudes include:
      • The Equator (0°)
      • The North Pole (90°N)
      • The South Pole (90°S)
      • The Tropic of Cancer (23.5°N)
      • The Tropic of Capricorn (23.5°S)

    Lines of Latitude

    • Lines of latitude are imaginary lines that connect points on Earth having the same latitude, running parallel to the Equator.
    • A latitude is the angular distance, measured in degrees, of a location north or south of the Equator.
    • Latitudes are parallel to the equator and each other.

    Main Latitudes

    • The equator is the largest latitude line.
    • The north pole is at 90°N
    • The south pole at 90°S
    • The tropics of cancer and capricorn are located 23.5° north and 23.5° south of the equator, respectively.

    Northern and Southern Hemispheres

    • The Equator divides the Earth into the Northern Hemisphere and the Southern Hemisphere.
    • Each hemisphere is equal in area.

    Uses of Latitudes

    • Use latitudes to determine locations' position relative to the equator.
    • Use latitudes to measure distances from the Equator.
    • Use latitudes to divide the Earth into temperature zones.

    Lines of Longitude

    • Longitude is the angular distance east or west of the Prime Meridian.
    • The Prime Meridian is the line of longitude at 0°.
    • It passes through Greenwich, England.
    • There are 360 lines of longitude at 1° intervals.
    • A longitude line is a meridian.
    • Longitude lines meet at the poles.

    Longitude and Time

    • Longitude is used to determine local time.
    • If it's noon at a specific longitude, it's also noon at all locations on that same longitude.
    • East of the Prime Meridian, gain time, west, subtract time.
    • Earth is divided into time zones based on 15° longitude intervals, with a 24-hour standard time system.

    International Date Line

    • The 180° meridian is the International Date Line.
    • Crossing the line eastward subtracts a day, westward adds a day.
    • The date line is not a perfectly straight line, it zigzags to avoid countries having different dates.

    Locating Places

    • Places can be located using latitude and longitude coordinates.
    • The latitude and longitude for a specific location can be used to find it on a map or globe.

    Great and Small circles

    • A great circle is a circle drawn on a sphere that passes through the sphere's center.
    • The smallest distance between two points on a sphere is along a great circle.
    • Great Circles are used to determine shortest distance between two points on a sphere.
