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.
What is the intersection of 2 lines called?
the coulor green
How does index contour lines differ from other contour lines?
Index contour lines are thicker and usually have their elevation labeled. They help users quickly identify key elevations on a topographic map. In contrast, regular contour lines show the shape and elevation of the land but do not have specific labels.
What is the difference in elevation between two contour lines that are side by side?
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.
What is the definition of a contour interval?
The definition of a contour interval is the difference in elevation between two consecutive lines.
What are the main topographic map rules?
The main topographic map rules include contour lines never crossing, contour lines close together represent steep terrain, contour lines spread out represent flat terrain, and elevation is indicated by the contour lines.
What arrangement of contour lines shows that the land is steep?
The land is steep if the contour lines are close together
What happens on a topographic map the closer the contour lines get?
The closer the contour lines, the steeper is the slope.
On a topographic map contour lines that are closer together indicate?
On a topographic map, contour lines that are closer together indicate a steeper slope.
What is the name for the elevation difference between adjacent and contour lines?
The name for the elevation difference between adjacent contour lines is the contour interval.
If two contour lines are marked 10m and 20m what is the contour interval between them?
The contour interval between two contour lines marked 10m and 20m is the difference in elevation between the two lines. In this case, the contour interval is 20m - 10m = 10m. Therefore, the contour interval is 10 meters.
