What is the elevation difference between contour lines?
The elevation difference between two adjacent contour lines is called the contour interval (CI). Usually the contour interval is noted on the map legend. In most topographic maps every 5th contour line is drawn in bold print or wider than other contours.
What is the name for the elevation difference between?
ANSWER: The name for the elevation difference in between two adjacent contour lines is contour interval. EXPLANATION: Counter lines are the line on the map that is drawn between two places at same altitude from the sea level.
When you move from one contour line to another the elevation?
If you move from one contour line to another, you move either up or down in elevation. In real life, if you walk across contour lines represented on the map, you will go either uphill or downhill. Elevation changes rapidly if contour lines are close together. A steep hill is represented by closely spaced contour lines.
What is the difference between a line and a contour?
is that contour is an outline, boundary or border, usually of curved shape while line is a path through two or more points (compare ‘segment’ ); a continuous mark, including as made by a pen; any path, curved or straight or line can be (obsolete) flax; linen, particularly the longer fiber of flax.
What is the distance between contour lines called?
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.
What is the zero contour line?
contour interval. The zero contour line is. sea level. the line that is shaded darker than the rest is the. index contour.
What do topographic maps show us?
Topographic maps are a detailed record of a land area, giving geographic positions and elevations for both natural and man-made features. They show the shape of the land the mountains, valleys, and plains by means of brown contour lines (lines of equal elevation above sea level).
What is the distance between two contour lines?
Contour Interval The difference in elevation between successive contour lines on a given map is fixed. This vertical distance between any two contour lines in a map is called the contour interval (C.I.) of the map. Figure 1.1 (a) shows contour interval of 1m whereas Figure 1.1 (b) shows 10m.
What is the difference between contour line and Formline?
Contours : A contour is an imaginary line (drawn on map) joining the points having the same elevation above the sea-level. Form Lines : These are broken lines. This method is used in association with contours to show the hilly or mountainous country. They are drawn without any precise measure units.
