1. As we go through the power point, please do the
following:
topography The study…
 Match your cards.
 Take notes in your science notebook.
 Label your map.

2. The study of the shapes and features of the Earth’s
surface.

3. Shows the three dimensional shape and
elevations of an area of land in two dimensions

4. Height above sea level

5. Line that connects places on a topographic map
that are all at the same elevation (eventually a
closed loop)
 Label the contour lines on your map.
Contour line

6. The vertical difference in elevation between
neighboring contour lines
 Label the contour line interval on your map.
contour line interval

7. The difference between the highest elevation
point and the lowest elevation point on a map

What is the relief of this map?
What is the contour interval of this map?

8.  Contour lines are closely spaced on steep slopes.
 Contour lines are widely spaced on gentle slopes.

9. Where a contour line crosses a stream or valley, the
contour line bends to form a “V” that points
upstream. In the upstream direction, the successive
contours represent higher elevations.

10.  Contour lines near the top of a hill form
closed, circular shapes. The top of the hill is
higher than the highest closed contour line.

11.  Depressions without outlets are shown by closed
hatched contours. The contour lines have short
lines on the inside that are pointing down slope.
The bottom of the depression is lower than the
lowest closed contour line.

12. A map made of pictures of the Earth taken from a
satellite orbiting the Earth.
