Would a topographic map of the Great Plains have a large or small contour interval?
A topographic map of the Great Plains would have a large contour interval because the Great Plains are relatively flat..
What are the 3 types of contour lines?
There are 3 kinds of contour lines you’ll see on a map: intermediate, index, and supplementary.Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. … Intermediate lines are the thinner, more common, lines between the index lines.More items…
What are the 5 Rules of contour lines?
Rule 1 – every point of a contour line has the same elevation. Rule 2 – contour lines separate uphill from downhill. Rule 3 – contour lines do not touch or cross each other except at a cliff. Rule 4 – every 5th contour line is darker in color.
Who would use a topographic map?
Hikers, campers, snow skiers, city and county planners, the Fish and Wildlife Service, Forest Service, miners, loggers, highway planners and construction workers, travelers, surveyors, geologists, engineers, and scientists are just a few of the people who use topographic maps.
What do V shaped contour lines pointing downhill indicate?
You know that you’re looking at a valley bottom when contour lines are V or U-shaped. All rivers flow downhill from higher to the lower elevations, perpendicular to the contour line above it.
What is the importance of contour lines?
The purpose of contour lines is to represent the tridimensional shape of the terrestrial surface on a bidimensional map. Contour lines are the intersection of an horizontal plane parallel to the reference level and the topographical surface to describe.
When contour lines are close together on a topographic map that means the area is steep?
If contour lines are close together, it is a very steep slope; if they are far apart, it is a gradual slope.
What is the topography like when the lines are far apart?
This is the elevation of the contour line, relative to mean sea level. Contour lines that are relatively close together indicate a slope that is fairly steep. Contour lines that are further apart indicates a slope that is relatively flat.
What is a depression contour line?
A closed contour, inside of which the ground or geologic structure is at a lower elevation than that outside, and distinguished on a map from other contour lines by hachures marked on the downslope or downdip side.
What does topography mean?
Topography is the study of the forms and features of land surfaces. The topography of an area could refer to the surface forms and features themselves, or a description (especially their depiction in maps).
Why do contour lines never cross?
Contour lines can never cross one another. Each line represents a separate elevation, and you can’t have two different elevations at the same point.
What is meant by contour interval?
A contour interval is the vertical distance or difference in elevation between contour lines. Index contours are bold or thicker lines that appear at every fifth contour line. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing.
How close the contour lines are is an indication of an area’s?
The arrangement of the contour lines on a map gives a direct indication of the changes in the field’s topography (Fig. 55). In hilly areas, the contour lines are close together while they are wider apart on flat slopes. The closer the contour lines, the steeper the slope.
What is the distance between contour lines called?
The space between the contour lines is called the contour interval and represents a specific (set) distance. If the contour interval is 50 feet, the vertical space between the two contour lines is 50 feet.
What exactly does a contour line show?
Contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level. The diagram illustrates how contour lines show relief by joining points of equal elevation.
How do you explain topography?
Topography describes the physical features of an area of land. These features typically include natural formations such as mountains, rivers, lakes, and valleys. Manmade features such as roads, dams, and cities may also be included. Topography often records the various elevations of an area using a topographical map.
