slope. Inclass textbook pg115-116;118-120
Bellwort: How fast was the car going if the car moved 16 miles in 2 minutes? Speed Rate= distance/time
Showing Elevation - Contours
Contour Lines
Contour Intervals
Map Scale
What is the approximate
distance from A to B? Use
your scratch paper as a marker
then use the scale to estimate
the distance.
What is the approximate
distance from C to D?
What is the elevation of the
peak on this island?
What is the contour interval of
the topographic map?
Depression Contours
How are contour lines drawn on maps?
How does a contour map show whether a slope is gentle or steep?
Define contour intervals and give examples of large and small contours intervals?
Distinguish between the use of the contour interval and the map scale?
How are cliffs shown on a topographic map?
How are creeks shown on a map?
The average slop or gradient between any two points of an interval is calculated using the following relationship:
