How does index contour lines differ from other contour lines?
index contour lines have numbers contour lines dont
How do you use contour lines?
Contour lines are lines that connect points of equal elevation. A topographical map is a map that uses contour lines to represent the elevation of land surfaces.
The heaviest contour lines on a topographic map are?
an index contour.
Why can't two contour lines overlap?
One contour can not cross another because a contour is one exact elevation; if it crossed another contour it would show that it is higher than the second contour on one side, but lower on the other side.
Contour lines on a topographic map indicate?
Usually the altitude above sea level. Close lines indicate a steep slope while spread out lines show flatter terrain.
What are the curves and closed loops on a topo map called?
They're called contour lines. They link places of similar elevation.
What is a darker contour line usually every fifth line?
It makes it easier to count the number of contour lines.
How does index contour lines differ from other contour lines?
index contour lines have numbers contour lines dont
What figures intersect but are not perpendicular?
Any lines or curves that are mutually skew.Any lines or curves that are mutually skew.Any lines or curves that are mutually skew.Any lines or curves that are mutually skew.
What are the factors effecting contour intervals?
If the contour interval is not given, find two reference (labeled) contour lines and find the number of lines between them, excluding the reference lines themselves. Then the interval can be found using the following formula: |(Difference between elevation of reference lines)| /(Number of contour lines between reference lines +1) = Contour interval For example, if you find two reference lines labeled 150m and 250m and there is one contour line between them, then |150m-250m|/(1+1)=100m/2=50m The contour interval of that map is 50 meters.
What involves plowing along curves?
Contour farming.
On a topographic map contour lines that are close together indicate a?
A very steep regionClosely spaced contour lines indicate a very steep slope.Conversely, widely spaced lines indicate areas that are nearly flat.-Leftover.Tech
How do contour lines show elevation?
The darker contour lines on map are called index contour lines. Numbers that indicate elevations are often written on these lines.
What is the definition of hachured contour lines?
Hachured contour lines are contour lines with ticks pointing downslope that indicate a depression on a topographic map.
How big is a contour line?
It depends how steep the mountain or hill is, usually the contour lines are bolded and is every fifth line. hope this helped
What are the characteristics of contour?
One of the characteristics of contour is that the variation of the vertical distance between any of the two contour lines are usually assumed to be uniform. The other characteristic is that all the points on a contour line are of the same elevation.
How do you use contour lines?
Contour lines are lines that connect points of equal elevation. A topographical map is a map that uses contour lines to represent the elevation of land surfaces.
