Latitudes And Longitudes

Front 1

Erathosthenes

Back 1

Greek philosopher and mathematician, calculated the earth's size, realised any place could be located by a grid of Latitudes and Longitude.

Front 2

Relative Location

Back 2

place relating to another place, EG : "Take a left from the bus stop."

Front 3

Absolute Location

Back 3

Position of a place based on the coordinates of a grid system. EG : "41.45 defree north latitude and 72.40 degree west longtude."

Front 4

Latitude

Back 4

The angular distance of a place north or south of the equator.

Front 5

Angular Distance

Back 5

The distance which is measured in degrees or "° "

Front 6

Zenith distance

Back 6

Angle that the sun makes at noon with the Zenith.

Front 7

Zenith

Back 7

The point in the sky vertically above the observer.

Front 8

Declination of the sun

Back 8

The angle the sun makes north or south of the equator on a particular day.

Front 9

Torrid Zone

Back 9

Between Tropic Of Cancer and Tropic Of Capricorn. Recieves direct rays of sun almost throughout the year. Is the hottest.

Front 10

Temperate Zone

Back 10

Between Tropic of cancer and Arctic circle in the northern hemisphere and between the Tropic Of Capricorn in the and Antarctic circlle in the southern hemisphere.

Front 11

Frigid Zone

Back 11

Near the polar regions, suns rays are very slanted so it is very cold. Between arctic circle and north pole in the north and antarctic circle and south pole in the south. (Frigid = Cold)

Front 12

Longitude

Back 12

The angular distance of a place east or west of the prime meridian (aka Zero meridian and Fixed meridian)

Front 13

Time zones

Back 13

Area in the world where clocks record the same time.

Front 14

Standard Fleming

Back 14

Canadian, suggested dividing the earth int 24 time zones.

Front 15

Local Time

Back 15

Time of a place reckoned by mid-day sun.

Front 16

Standard Time

Back 16

When the local time of a central place is taken as the time for the whole country (or large area) .

Front 17

International Date Line

Back 17

The line at which a day is gained, not a straight line, passes over only sea or oceans , at the 180° latitude. West to East a day is lost, East to West a day is gained.
