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.
Who invented the contour line?
The concept of contour lines in cartography was developed by the French engineer and cartographer, Charles Picquet, in the early 18th century. Picquet used these lines to represent elevation on maps and later this became a common practice in topographic mapping.
Lines connecting all points at the same elevation on a contour map are called?
Contour lines.
Contour lines connect points with the same what?
Contour lines connect points with the same elevation or altitude. These lines are used on maps to help visualize the shape and elevation of the terrain.
Contour lines on a map indicate?
Contour lines on a map indicate elevation. They connect points of equal elevation, showing the shape and steepness of the terrain. Closer contour lines indicate steep slopes, while spaced-out lines represent flatter areas.
How does index contour lines differ from other contour lines?
index contour lines have numbers contour lines dont
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 do you use contour lines?
Contour lines are lines that connect points of equal elevation. A topographical map is a map that uses contour lines to represent the elevation of land surfaces.
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 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 relief is shown using what?
countour intervals
What does a contour line measure?
The scale of contour lines on a topographic (terrain) map is called the "contour interval".
Who invented the contour line?

What are lines on a farm called?
contour lines
The heaviest contour lines on a topographic map are?
an index contour.
How do contour lines show stream direction?
indicated with different kind of contour numbers , which are showed in brown curved lines
