1. What is the map’s contour interval?
The _____________________________ that each line is increasing by.
Label the picture as it is done in the video.
2. What is the highest/lowest elevation on the map?
The contour interval in this map is ___________________________, so the line at the top is _________.
Because the X is inside the 1600 line, then the elevation must be __________________ than 1600. There
is no 1700 line, so point X is __________________________ than 1600 and less than
________________. The highest possible elevation of point X is ________________.
Circle where the lowest elevation is on the map.
The lowest line is _________. That means the
lowest possible elevation on the map is less than
_____________ but more than __________.
3. Where is the steepest/flattest slope located?
Circle the steepest area on the map.
Wherever the contour lines are really __________
together there is a _____________ slope. There is
a big change in elevation over a ___________
distance.
Put a box around the flattest area on the map.
Wherever the contour lines are spread
____________ apart, there is a gentle slope.
4. What direction is the stream flowing?
Rule #1: Streams always flow _________________, from __________ elevation to _________elevation.
Rule #2: Steams always flow ______________________________ the bends in the contour line.
Label the maps as in the video.
5. What is the gradient of a particular slope?
Gradient is a measure of how steep a slope is. The formula is:
Field value refers to the change in _________________. To find distance, you need to use the _______
__________________ and line it up between the two points.
Elevation of X = _________
Elevation of Y = _________
Distance = ________ miles
Gradient = ______ft - ________ft
Miles
Gradient=
6. What does the landform’s profile look like? Draw the profile as shown in the video.

A profile is a side view of a landscape.
Line the scrap paper up with the line you are drawing the profile on.
Mark anywhere a contour line crosses the scrap paper. Label the mark with the elevation of the
contour line.
Place the scrap paper at the bottom of the graph.
Plot points on the graph.
Connect dots with a smooth curving line.
