Enduring Understanding Themes

1. Enduring Understanding Themes Location, Place, & Region August 12-13, 2013

2. FIRST FIVE Agenda Message for August 12, 2013: We begin Social Studies with understanding how geographers describe locations by use of Hemispheres, Latitude & Longitude, Equator, Prime Meridian, and the use of Maps. Standard: Location affects a society’s economy, culture, and development. E. Q. for Monday, August 12, 2013 What are the two ways that geographers describe location? Warm-Up: Describe where the City of Atlanta is to someone who has never been there.

3. Geographic Location The two ways geography describes location are; • Relative location describes a place in comparison to other places around it. • Absolute location is the exact place on earth where a geographic location, such as a city is found.

4. Geographic Location • Relative Location Relative location describes where a place is in relation to its surrounding environment. For example, you may tell a person that the library is three blocks west of the park.

5. Geographic Location • Absolute Location To describe absolute location, geography uses a grid system of imaginary lines for precisely locating places on the earth’s surface. ~Hemispheres ~Equator ~Prime Meridian ~Latitude Lines ~Longitude Lines

6. Geographic Location • Earth is divided into two equal halves. Each half of the globe is called a hemisphere. • Because the earth is round, a hemisphere can be north and south, or east and west.

7. Geographic Location • The equator is the imaginary line that divides the north and south halves (hemispheres). • The prime meridian is the imaginary line dividing the east and west (hemispheres). (Sometime this is called the Greenwich meridian because it runs through the town of Greenwich, England.)

8. FIRST FIVE Agenda Message for August 13, 2013: Homework due Wednesday: Draw a globe using graph paper. Draw and label North, South, East, & West, Equator, Prime Meridian, Latitude lines & longitude lines. Standard: Location affects a society’s economy, culture, and development. E. Q. for Tuesday; August 13, 2013: What are the imaginary lines called that run parallel to the equator? Warm-Up: Describe where Douglasville is located to someone who has never been here.

9. Geographic Location • Latitude Lines To locate places north or south, geography uses a set of imaginary lines that run parallel to the equator. These lines are called latitudelines. The equator is labeled as the zero-degree line for latitude.

10. Geographic Location • Latitude Lines cont. Lines north of the equator are called “north latitude” lines and lines south of the equator are called “south latitude” lines.

11. Geographic Location • Longitude Lines To complete the grid system, geography uses a set of imaginary lines that go around the earth over the north and south poles. These lines are called longitude lines, and mark positions in the east-west hemisphere. The prime meridian is the zero-degree line for longitude. Just as the equator is the zero-degree line for latitude.

12. Geographic Location Each site on the earth can have only “one” absolute location. To find an absolute (or “precise”) location using the grid system, you need to find the point where the latitude and longitude lines cross.

13. Geographic Location Vocabulary Words for Location • Absolute location • Relative location • Hemisphere • Prime meridian • Latitude line • Longitude line • Equator

14. Latitude & Longitude Practice Find the following countries: • 20o N/50o E • 30o N/60o E • 40o N/40o E • 20o N/80o E • 40o N/100o E • 30o N/70o E • 30o S/10oE • 0o/30o E
