Station #1 Making A Contour Map Directions: 1) Note the contour interval at the bottom of the map.2) Assume that the data was measured in meters at the center of each number.3) To make contour lines start by finding the lowest multiple of the contour interval. On this map the lowest value is ____. Highlight these with the same color. Using a pencil connect them with a smooth line that separates values that are lower and higher. 4) Now draw the next contour line, since our interval is 10m this value is _____. Using a different color highlight all these values. Now connect these points with a smooth line using a pencil. Remember that this line should separate elevations that are greater and less.5) Make the remaining contour lines

Station # 2 Contour Mapping
1. What is the contour interval of this map? ______________2. Number all the contour lines.3. What is the scale of miles of this map? ______________4. By means of the scale, measure the distance from the top of hill B to the top of hill A. _______5. Which side of hill A has the steepest slope? _____________________6. How can you tell whether a landform has a steep or gentle slopes? __________________________________________________________________________7. In what direction from hill A is hill B? ___________8. What is the elevation above sea level of hill A?9. a) Which of the two hill is higher? _________ b) How much higher? _______________10. If you climbed to the top of hill B from C, how many feet would you climb?11. In what direction is the Red River flowing? _________________ How do you know? _________________________________________________12. Shade the area on the map which would be under water if the sea level rose 40 feet.13. Calculate the gradient of the Red River from point D to the ocean.
Station # 3: Drawing a Profile
1. What is the gradient of the slope between point A and point B. Show all work including the formula.
2. Construct a profile of this map from point C to D.
Station # 3: Drawing a Profile
Station #4: Contour Mapping Rules
Directions: Read these rules and use them to fill in the blanks for the Conclusion Questions.
1. A contour line represents a single equal elevation: that is, all points on the same contour
line have the same elevation.
2. Where one closed contour line surrounds another, the inner contour line represents the
higher elevation.
3. The elevation represented by a contour line is always a simple multiple of the contour
interval.
4. A contour line that closes within the limits of the map indicates a hill, ridge or plateau.
5. Commonly, every fifth contour line (index contour) is darker and its elevation is shown.
6. On the same map, closely spaced contour lines indicate a relatively steep slope, widely
spaced contour lines indicate a relatively gentle slope, and uniformly spaced contour lines
indicate a uniform slope.
7. Contour lines do not cross other contour lines. Exception: on a vertical cliff or a nearly
vertical cliff, contour lines touch because they are on top of one another
8. Every contour line eventually closes against itself. However, the map area may not be
large enough to show this closure. Therefore, the contours will end at the edge of the map.
9. Closed depressions are shown by hachured contour lines. The hachures point into the
depression. (Hachures = short dashes)
10. A hachured contour line, lying between two different contour lines, is the same
elevation as the lower contour line.
11. Where two adjacent contours indicate opposite slopes (hachured contour next to plain
contour), both are the SAME elevation.
12. Where a contour line crosses a stream or valley, the contour bends to form a “V” that
points upstream or up the valley. Therefore the river flows opposite the direction of the “v”
13. A topographic map is aerial view of a location with contour lines that indicate areas of
equal elevation above sea level (sea level = 0m)
14.
Station #4: Contour Mapping Rules
Conclusion Questions
1. The difference in value between two contour lines is called the ____________.
2. The zero contour line is ______________.
3. The line that is shaded darker than the other contour lines is the _________________.
4. A topographic map shows ____________________________________________________.
5. The closer the contour lines, the __________ the slope; the father
apart the contour lines, the ___________ the slope.
6. Contour lines form ____________ when they cross streams or valleys.
This _________ points _____________ or ___________.
7. Closed depressions are shown by _____________________.
8. Every contour line eventually _______________________.
9. Gradient is equal to _________________________________. *First page of your ESRT*
10. A ___________________________ is a side view of a particular area.
11. The ________________________________ can be determined by
estimating the distance between contour lines
Station # 5: Critical Thinking (you can do it!)
An island measures 10 kilometers from east to west and 8 kilometers from north to south. A single hill on the east side of the island has a maximum elevation of 57 Meters and is steepest to the north. In the box below, draw a simple contour map to represent this island, using a distance scale of 1 centimeter = 1 kilometer and a contour interval of 10 meters.

Place Latitude LongitudeSouthern tip of FloridaEastern edge of IcelandSouthern tip of IndiaSouthern tip of GreenlandSuez Canal
Data Chart 2
Latitude Longitude Location (Country)40° N 140° E15° N 75° E45° N 90° W32° S 118° E30° S 20° E20° S 43° W
Conclusion Questions:
1. What is the highest number of degrees latitude that exists?
2. What is the latitude of the North Pole?
3. Explain why two lines of latitude never touch each other
Station # 7: Time Zones
Longitude lines have two major purposes. First when used in location. In addition, longitude lines also separate time zones.
Using a globe fill in Data Chart 3 with the appropriate information.
Column 1: # of degrees around the globe
Column 2: # of degrees between lines of longitude
Column 3: # of longitude lines around the globe (column 1/ column 2)
Questions:
1) What does the number calculated in column 3 remind you of?
2) How many hours are between each line of longitude
3) How many degrees longitude are equal to one hour of time?
4) If two cities are located on the same line of longitude, what else do the two cities have in common?
