The lines for depression are called hachured lines
Contour lines.
It depends completely on the type of map and the scale of the map. Look several contour lines above and below the area of interest. Often, the elevation is printed on every 5th contour line. Divide the difference by the number of spaces between the two lines. Example, one contour line says "1000" and the next one with an elevation says "1500". If there are 4 lines in between these two, it is 100 ft per contour line. In some areas, you will need to follow a contour line around the map to track down the elevation of that line. Easier still, check the legend on the side or bottom of the map. The example showing the colors or symbols used may also tell the contour interval if it is consistent for the entire map.
When the contour lines are farther apart, this means that the slopes between them are gentle. On the other side, if the contour interval is smaller, the slope will be steep.
The closer the contour lines the steeper the slope.
The difference in elevation between the highest and lowest contour lines on a topographical map is called a contour interval.
Contour interval.
The name for the elevation difference between adjacent contour lines is the contour interval.
Contour lines on a map represent points of equal elevation. The difference in elevation between any two contour lines is called the contour interval, which is usually indicated on the map legend. By knowing the contour interval, you can determine the steepness of the terrain in that specific area.
The difference in elevation between two contour lines that are side by side is the contour interval. The contour interval is the vertical distance between two adjacent contour lines on a topographic map.
The elevation difference between two side-by-side contour lines is known as the contour interval. It represents the vertical distance in elevation between each contour line on a topographic map.
The difference in elevation between two side-by-side contour lines on a topographic map is called the contour interval. It represents the vertical distance between each contour line and helps depict the steepness of the terrain.
the elevation difference between two adjacent contour lines.
The definition of a contour interval is the difference in elevation between two consecutive lines.
The spaces between the topographic lines are called contour intervals. They represent the difference in elevation between each line on a topographic map.
The contour lines on a topographic map represent the difference in elevation between two adjacent lines. The closer together the contour lines are, the steeper the terrain. If the lines are spaced far apart, it indicates a gentle slope. The contour interval, which is typically shown in the map's legend, specifies the difference in elevation between each contour line.
The change in elevation from one contour line to the next is called the contour interval. It represents the difference in elevation between two adjacent contour lines on a topographic map.
