rate of change from one plane to another

30
Q

What are topographic maps(contour maps)?

A

commonly used model of the elevation field of the surface of the Earth
- topographic maps show 3D shapes in 2D

31
Q

What is elevation?

32
Q

What are natural features?

A

features that are created by nature

33
Q

What are cultural features?

A

features that are created by mankind
EX: roads, cities, buildings, dams

34
Q

What is a contour interval?

A

the difference in elevation between 2 side by side contour lines
-the contour interval is usually found on the map key and legend

35
Q

What is an index cou=ntour?

A

lines that are bold and have an elevation label
EX: 200ft and 300ft

36
Q

What is a gentle slope?

A

when countour lines are spaced far apart

37
Q

What is a steep slope?

A

when contour lines are spaced close together

38
Q

When contour lines cross a river, they bend ________

A

upstream
-rivers flow the opposite direction the contour lines point

39
Q

What is a benchmark?

A

a marker that has the exact latitude, longitude, and elevation of that position
-labeled on a map BM.X

40
Q

What are depression contours?

A

marked with small lines called hochured lines that are pointed to the center of a depression

41
Q

What are the steps to calculating the highest point?

A

1) finding the last(highest) contour line on the hill
2) imagine you drew another line
3) subtract 1 from the imaginary line

42
Q

What are some contour line rules?

A

1) contour lines close around hills, basins, and depressions or extend the edge of the map
2) contour lines never ever cross
3) contour liens form V’s that point upstream whenever crossing a stream

43
Q

What is a topographic porfile?

A

the side view of a geologic feature

44
Q

What are the steps to creating a topographic profile?

A

1) you need 2 points on a contour map and a horizontal grid between the 2 points
2) transfer the points from the map to the horizontal grid
3) connect the points with a smooth line to draw a profile
