Introduction
Introduction

  • Lines of latitude and longitude are a grid of imaginary lines that cross the Earth.

  • These lines help us to find exact locations on the Earths surface.

  • Why do you think latitude

    and longitude are important?


Latitude
Latitude

  • Lines of latitude run around the earth from East to West, parallel to the equator.

  • The equator is an imaginary line that runs around the center of the earth from East to West. (like the Earth’s belt)


Longitude
Longitude

  • Lines of longitude run around the earth from North to South. These lines are not parallel and will intersect at the north and south poles.

  • The prime meridian is

    considered the center

    line in dealing with

    Longitude.


Hemispheres
Hemispheres

  • The Earth is divided into four hemispheres.

  • The equator divides the earth into North and South hemispheres

  • The prime meridian divides the earth into East and West hemispheres.


Hemispheres1
Hemispheres

  • Every location on Earth will be located in exactly two hemispheres.

  • Which hemispheres are we in?


How to read coordinates
How to read coordinates

  • Latitude and longitude are expressed using coordinates.

  • Coordinates are two numbers expressed in degrees (⁰).

  • Example: 40⁰N, 30⁰W

    is read as 40 degrees North, 30 degrees West

  • Things to remember…

    • Latitude always comes first

    • Longitude always comes last
