Q

Are series of short lines drawn in the direction of the slope. They only provide a general impression of the configuration of the ground, they don’t provide the actual elevation of the ground surface.

Q

Are drawn when not enough vertical control is available or when the surface is too irregular or intricate contour. They are usually represented as dashed lines and do not portray any actual elevations. They are used to show the shapes of the terrain rather than relief.

Saddle

25
Q

Flows downhill and contours point to higher ground.

A

River

26
Q

Contours for a V or U shape pointing to the higher ground.

A

Valley

27
Q

Contours on both sides of a narrow valley are very steep.

A

Gorge

28
Q

Contours on top or almost on top of each other

A

Cliff

29
Q

The vertical distance between adjacent contour lines.

A

Contour Interval

30
Q

A line connecting points of equal elevation. It may be marked by its elevation in feet above sea level.

A

Contour Line

31
Q

The vertical distance of a point above a reference plane. On a topographic map, the plane is usually mean sea level.

A

Elevation

32
Q

The distance in elevation between the top of an object and its base.

A

Height

33
Q

The difference in elevation between the highest point and lowest in an area, or as shown on a topographic map.

A

Relief

34
Q

A map showing the shape of the land surface.

A

Topographic Map

35
Q

The set of physical features - mountains, hills, valleys, and other landforms that characterize a landscape

A

Topography

36
Q

A point or small area of high ground. The ground slopes down in all directions.

A

Hill

37
Q

A line of high ground with height variations along its crest.

A

Ridge

38
Q

Reasonably level ground is bordered on the sides by higher ground. Contour lines are U-shaped and tend to parallel a stream before crossing it.

A

Valley

39
Q

A dip or low point along the crest of a ridge. It may be a break along an otherwise level ridge crest.

A

Saddle

40
Q

A low point or hole in the ground, surrounded on all sides by higher ground.

A

Depression

41
Q

This is similar to a valley, except that it normally is a less developed stream course in which there is generally no level ground and. therefore, little or no maneuver room.

A

Draw

42
Q

A usually short, continuously sloping line of higher ground, normally jutting out from the side of a ridge.

A

Spur

43
Q

A vertical or near-vertical slope. It is shown in a map as lines being close together, touching, or by a ticked “carrying” contour line.

A

Cliff

44
Q

Is shown by heavier lines at regular intervals on a topographic map. They are usually shown every 5th contour and carry the contour number or elevation designation.

A

Index Contours

45
Q

Lines found between the index contours.

A

Intermediate Contours

46
Q

In a certain portion of the map, the intermediate contours are so closely spaced that they nearly unite or merge into a single line. It is standard practice for readability not to portray the line for short distances.

A

Feathering

47
Q

are drawn to show low spots as excavations around which contour close.

A

Depression Contours

48
Q

They are drawn as dashed lines or lines that begin and end when they approach the areas where the regular contours close in on each other.

A

Supplementary/ Auxillary Contours

49
Q

The map markers have to make an educated guess rather than have a blank area on the map.

A

Approximate Contours

50
Q

Every contour ___ on itself, either within or beyond the limits of the map.

A

Closes

51
Q

Contours are spaced ___ on a uniform slope.

A

Evenly

Q

Contours are _____ to each other on a plane surface.

A

Straight and Parallel

53
Q

Irregular contours signify ____ terrain.

A

Rough and Rugged

54
Q

Contour interval for flat to gently rolling.

A

1 to 5 meters

55
Q

Contour interval for hilly

A

5 to 20 meters

56
Q

Contour interval for Mountainous

A

25 to 100 meters

57
Q

58
Q

A cross-sectional view along a line drawn through a portion of a topographic map.
