The Relationship between the relief of an area and the contour interval on a map of the area is A contour line
It depends on the scale of the map, the range of values attained within the area of the map, the units of measurement and the accuracy of the contour data.
They show the relief of an area. They will have height values attached to them. The distance between contour lines gives an impression of gradient. The closer they are together, the steeper the slope.
Roxanne Lipsey: Contour lines are drawn at specific intervals, such as every 10 feet, 20 feet or 30 feet. Each line represents a multiple of the scale chosen. Using the 10-foot scale as an example, each contour interval would represent a 10 feet change in elevation.
Contour intervals are the vertical distance between two adjacent contour lines on a map. Contour lines are lines that connect points of equal elevation on a map, allowing you to visualize the shape and steepness of the terrain. By studying contour lines and their intervals, you can determine the elevation changes and topography of an area.
It means that it isnt very mountainy and has low flat ground.
It depends on the scale of the map. If it is a trecking map then 5 m, but for driving maps or similar, 30m contours would be fine.
The closer the contour lines the steeper the slope.
Florida is low relief.
The steeper the slope, the contour lines go further along the area. You can also determine the flatness of the area with these lines.
elevation
Slope, or percent of grade.
