Relative and Absolute Location Where Are WE How

Relative and Absolute Location Where Are WE?

How Do We Get There? • There are two ways to answer this question…. if you would like to determine a place’s location relative to someplace else, then you are looking at its RELATIVE LOCATION. • For Example: Kentucky is south of Ohio. OR • Meet me at the Starbucks that is next to Izzy’s on Mall Road.

Relative Location • We are going to focus on Relative Location for a moment. I would like for you to be able to refer to places on a map in terms of where they are located relative to other places…. . And I want you to use your cardinal and intermediate directions correctly.

Let’s Review • Cardinal Directions • Intermediate • NORTH Directions • South • East • West • • Northeast Southeast Northwest Southwest

Your Task • Open you textbook to pages R 46 -R 47. • Use the map on those pages and answer the following five questions: – 1. China is ________of Thailand. – 2. Libya is _________ of Egypt. – 3. Peru is ________ of Brazil. – 4. Spain is _________ of France. – 5. Yemen is _______ of Saudi Arabia.

Your Task • Using the maps in the back of our textbook write three statements using Cardinal directions and three statements using intermediate directions. • Make sure you write the page number of the map you are using next to each sentence. • Example: • Map Page R 49……Honduras is southwest of Cuba.

Absolute Location • Where a place is SPECIFICALLY located. • This is done in one of two ways. 1. A person given you an exact address. For example: 2304 Oakview Court Hebron, KY 41048 2. Using imaginary lines of Latitude and Longitude For example: 65°N / 32°W

Understanding Latitude and Longitude Let’s SEE what we can LEARN!

System of Imaginary Lines • Now let’s look at the grid system that has been created to help us locate any point on a map. • To do this we used lines of Latitude and lines of Longitude.

Latitude and Longitude • The earth is divided into lots of lines called latitude and longitude.

North, South, East and West on The Earth Y • Let the X axis be the Equator. • Let the Y axis be the Prime Meridian X that runs through Greenwich outside of London. • Latitude and Longitude are the 2 grid points by which you can locate any point on earth.

East West, North South on the Earth (N, W) Prime Meridian • That means all points in North America will have a North latitude and a West longitude because it is North of the Equator and West of the Prime Meridian.

East West, North South on the Earth Prime Meridian ? • What would be the latitude and longitude directions in Australia?

Lines of Latitude • Lines that run east and west but measure distance north and south of the equator. • Latitudes lines are always written first when given the coordinates of a place. • They will always be either North or South.

Where is 0 degree Latitude? • The equator is 0 degree latitude. • It is an imaginary belt that runs halfway point between the North Pole and the South Pole. Equator

What is Latitude? 90°N Y X 90°S • Latitude is the distance from the equator along the Y axis. • All points along the equator have a value of 0 degrees latitude. • North pole = 90°N • South pole = 90°S • Values are expressed in terms of degrees.

Lines of Longitude • Lines that run north and south around the earth, but measure distance east and west of the Prime Meridian. • They will always be either east or west

Where is 0 degree Longitude? • The prime meridian is 0 degrees longitude. This imaginary line runs through the United Kingdom, France, Spain, western Africa, and Antarctica. P M E R R I I D M I E A N

What is Longitude? Y 180°W • Longitude is the distance from the prime meridian along the X axis. • All points along the X prime meridian have a value of 0 degrees longitude. • The earth is divided into two parts, or 180°E hemispheres, of east and west longitude.

What is Longitude? Y X 180°W 180°E • The earth is divided into 360 equal slices (meridians) • 180 west and 180 east of the prime meridian

So Where is (0, 0)? • The origin point (0, 0) is where the equator intersects the prime meridian. • (0, 0) is off the western coast of Africa in the Atlantic Ocean.

East West, North South on the Earth N W E S • Let each of the four quarters then be designated by North or South and East or West.

East West, North South on the Earth (N, W) (S, W) (N, E) (S, E) • The N tells us we’re north of the Equator. The S tells us we’re south of the Equator. • The E tells us that we’re east of the Prime Meridian. The W tells us that we’re west of the Prime Meridian.

See If You Can Tell In Which Quarter These Latitude and Longitude Are Located A C • • B • D • • • 1. 41°N, 21°E 2. 37°N, 76°W 3. 72°S, 141°W 4. 7°S, 23°W 5. 15°N, 29°E 6. 34°S, 151°E
