FranAn interpretation of the contour lines gives us an idea of the gradient of the data being presented. The contour lines on the weather map represent points of equal pressure. The contour lines of the lines of magnetic force on the surface of the Earth give some insight to the interior of the Earth.
Contour lines were first used (as far as I know) in the Schiehallon Experiment, which was an attempt to measure the mass of the Earth. For the measurement of the volume of the small mountain, the concept of slicing the mountain into a set of equal-height countours.

Contour interval is what?
the elevation difference between two adjacent contour lines.
What is the relationship between the relief of an area and the contour interval on a map of the area?
The Relationship between the relief of an area and the contour interval on a map of the area is A contour line
What information does a map's contour interval provide?
Most likely you says about contour interval. It's the difference in height between two sequential contour lines. For example, if the contour interval is 50 meters and some contour line corresponds 2000m above sea level, the next contour uphill was at 2050m then 2100m etc. Different maps use different intervals. It depends on map scale and terrain type (for mountain areas intervals are higher than for plains). The contour interval is shown on the map collar (typically near the scale).
What does it mean if the contour interval on map is 25 feet?
A contour interval of 25 feet means that, between one contour and the next on a map, the ground rises (or falls) 25 feet. Contours closer together means that the slope is steeper, and contours further apart suggests a shallower incline.
On a topographic map what indicates the difference in elevation between adjacent lines?
Contour interval
