What are Isolines that show elevation called?
contour lines
Isolines, also referred to as contour lines, can be used to represent elevation on a map by connecting points of equal elevation, for instance. These imaginary lines provide a good visual representation of the terrain.
What is change in elevation called?
Change in elevation is called. relief. .
What is the elevation 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 difference in elevation between each contour line 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 an ISO elevation?
These are usually referred to simply as contour lines. …
What are called Isolines?
Isolines are lines drawn on a map connecting data points of the same value. They are commonly used by geographers. Contour lines, for example, show relief and connect points on the map that have the same height.
What is the change in elevation from one contour line to the next?
contour interval
The difference in elevation between one contour line and the next is called the contour interval. The contour interval is selected based on the relief of the area being mapped. Every fifth contour line is darker than the four lines one either side of it. This index contour makes reading elevation easier.
What two types of lines show elevation differences?
Topographic maps have contour lines that connect points of identical elevation above sea level. Contour lines run next to each other. Adjacent contour lines are separated by a constant difference in elevation, usually noted on the map. Topographic maps have a horizontal scale to indicate horizontal distances.
What connects points of equal elevation?
contour
A contour is an imaginary line that connects points of equal elevation. A contour line may represent a visible line such as a lake shoreline, but usually contours are sketched between and around points of known elevations, as shown in the graphic.
