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 do the numbers on index contour lines indicate?
The numbers of contour lines indicate altitude or elevation along that line.
Contour lines that are widely space indicate what?
If the contour lines on a topographic map have wide spaces in between and are further apart then the terrain is relatively flat. If the contour lines are close together then the terrain forms a steep slope.
What do elevation maps use to show elevation?
Maps can show elevation with contour lines
How do you determine the elevation of unlabled contour lines?
The distance in height between contour lines should be stated in the map's legend. If the contours are stated in the legend as being 50 metres apart, then count the lines upwards from a contour that has a height against it, and multiply by the number of unlabelled lines.
Use contour lines to show the landform for plateau?
Contour lines that are evenly spaced and parallel indicate a plateau. The closer the contour lines are to each other, the steeper the terrain; the farther apart they are, the flatter the land. In the case of a plateau, contour lines would likely be spaced evenly and relatively close together, indicating a flat or gently sloping landform.
What is the contour line of a plateau?
Plateaus are large fairly plat pieces of uplifted land surrounded by steep slopes. A landform can be identified as a plateau when the contour lines are quite close to each other all around while on the upper slopes there are no lines or hardly any lines signifying that the top is rather flat.
How would a plateau be represented on a topographic map?
A plateau on a topographic map would typically be shown as a flat or gently sloping area with contour lines that are spaced more widely apart compared to steeper terrain. The contour lines may run parallel to each other, indicating a relatively uniform elevation across the plateau.
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 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 map symbol of plateau?
The map symbol for a plateau is typically represented by contour lines that are close together and relatively flat compared to surrounding terrain. Plateaus are shown as elevated flat areas 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 happens on a topographic map the closer the contour lines get?
The closer the contour lines, the steeper is the slope.
What arrangement of contour lines shows that the land is steep?
The land is steep if the contour lines are close together
