1. The International Date Line
There are 180 lines of longitude on each side of the prime meridian.
On the opposite side, the prime meridian is not zero, but 180˚.
It is called the International Date Line.

2. Practice Questions North South Prime Meridian East West 180
Longitude lines connect the ____________ pole with the ________________ pole.
The line of 0˚ longitude is called the ________________________________.
Longitude gives directions ___________ and _____________ of the prime meridian.
There are ___________ degrees of longitude on each side of the prime meridian.
North
South
Prime Meridian
East
West
180

3. Using Latitude & Longitude
Latitude and longitude can be used to find your exact location on a map.
You write latitude first followed by longitude.
Example:
Miami, Florida is located at 25˚ North and 80˚ West.
Or 25˚ N 80˚ W

4. Compass Rose
A figure on a map or compass used to show cardinal directions: North, East, South, & West.

6. What is Topography?
Topography is the physical and natural features of the land
A topographic map shows natural features (such as elevation) and man made features (such as schools)

7. What are Contour Lines?
The lines on a topographic maps are called contour lines
Contour lines show elevation or height
Contour lines of the same elevation are connected

8. What are Contour Lines?
Topographic maps are 2-D images that can be used to created 3-D images.

9. What are contour lines?
The closer the contour lines are to each other, the steeper the slope is

10. What are Some other Mapping Terms?
Map Scale- compares distance on the map with distance on Earth.
Legend – explains symbols used on the map.
Index contours – contour lines that are labeled to help you find the contour interval.
Relief- The difference in elevation between any 2 points
A contour interval is the difference in elevation between two contour line that are side by side.

11. How do you find the Contour interval?
To find the contour interval:
Find index contour
Determine the elevation between two index contours
Count the number of spaces between 2 index contours
Divide the elevation difference between the 2 index contours by the number of spaces
= 100
5 spaces
100 / 5 = 20

12. Practice Put a box around the map scale Is there a legend?
Circle at least one index contour
What is the contour interval? No
= 200
200 / 5 = 40

13. What Features are on Topographic Maps?
Mountains/ hills are represented by a series of circle
This is a top down view

14. WHAT Features Are on Topographic Maps?
A depression, or hole is represented with hachure lines.
An example may be the inside of a dead volcano
