divides the earth in half (north and south)?

What is the line of longitude that divides the earth in half (east and west)?

What hemispheres is the United States located in?

Quick Review

Hemisphere: Half of the Earth Line that divides north and south:

Equator Line that divides east and west:

Prime Meridian Hemispheres of United States: North

Quick Review

Latitude

Line of Latitude measure the distance (in degrees) north and south of the equator

The equator is 0 degrees They run east and west Think “ladder” for latitude

Longitude

Lines of longitude measure the distance (in degrees) east and west of the prime meridian

Prime meridian is 0 degrees International dateline is 180 degrees

What is the international dateline? They run north and south

International Dateline

Latitude and Longitude

What does the combination of both coordinates give you? Answer: Absolute location Example: Kansas City is 39 degrees N,

98 degrees W Practice: Approximate the

coordinates of Denver, CO using the map on the screen Do the same with Springfield, IL

Map of USA

Maps and Globes

Globe: 3D representation of the earth Pros: see the earth as it really is Cons: only see half at a time

Map: 2D representation of the earth Pros: See the whole world Cons: Can be distorted depending on

type of map A cartographer is someone who

makes maps

Political Maps

Uses: Show a very

specific type of information

Map Components

There are some components most maps will share

They are: Title Compass rose Legend/key Scale Latitude/Longitude

Title – purpose of map

Legend/key – tells us what things on the map mean

Scale – shows us distance

Latitude/longitude – gives us coordinates for locations

Compass rose – shows directions
