## Absolute Location

### 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

• 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

• 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

• 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.

### Hemispheres

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

• Which hemispheres are we in?

### 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

### How to read coordinates

• Things to remember…

• Latitude always comes first

• Longitude always comes last
