1. MAPPING THE EARTH

2. Latitude Horizontal, East to West lines dividing the Earth
Equator - O degrees latitude
Runs through the center of the Earth

3. Longitude Vertical, North to South lines dividing the Earth
Prime Meridian - 0 degrees longitude
International Dateline degrees longitude

4. How Many Time Zones??? 24

5. Why do we need time zones?
We have to keep the rotation of Earth in relation to the sun constant

6. Topographic (Contour) Maps
Show changes in the Earth’s elevation by using contour lines

7. How to read a contour map
The closer the lines are together, the more the slope is changing, and the steeper the slope.

8. How to read a contour map
The farther the lines are apart, the less the slope is changing, and the more gradual the slope.

9. Take a closer look If there is a river… lines point upstream
river flows against arrows

10. How can you tell the elevation?
The lines increase in a pattern.
Ex. 10’s, 20’s, 100’s

11. You Figure Out The Pattern…
