A contour line (also known as isopleth) on a topographic map connects points of equal elevation or depth. The steepest way up or down is in the direction perpendicular to the contour line at any given point. This gradient on a topographic map is at its greatest when the lines are close together, thus the slope is steepest.
Note that a contour map does not have to be topographic. Any value mapped in two or three dimensions such as temperature, barometric pressure, or wind speed can have contour lines connecting adjacent points of equal value. Again, moving away from a contour line in a perpendicular direction will yield the greatest change in the value of the quality being recorded.

How are contour lines shown for a gentle slope?
Contours for a gentle slope are spaced equally and far apart, the closer the contour lines the steeper the slope.
Are contour lines used to indicate horizontal distances or vertical distances on earths surface?
Horizontal
Why are the pages in the Bible in 2 columns?
It is easier to read small, closely spaced print when the lines are not very long. This is also why newspapers are written in columns.
How do contour lines determine which area of an island has the steepest slope?
The closer the contour lines the steeper the slope.
Why do gentle slopes have more widely spaced lines than steep slopes?
Presumably the questions refer to contour lines. If that is the case, the answer is as follows: Contour lines are lines drawn at selected heights on a map. They are lines that join points at the same height above the meas sea level. A gentle slope is one that does not rise (or fall) as rapidly as a steep slope. That is to say, you have to travel a greater horizontal distance to gain (lose) the same amount of vertical distance or height. So, with a gentle slope, you have to travel a greater distance to get from one contour to the next and so the lines are less close together.
Are contour lines closely spaced or far apart to indicate steep hills?
Closely spaced
What kind of slope do a closely spaced contour lines indicate?
Closely spaced contour lines mean that the slope is steep.
What do closely spaced contour lines on a topographic map indicate?
Closely spaced contour line on a topographic map shows that the land is steep.
Long closely spaced oval contour lines may indicate?
ridges
What does the spacing between contour lines tell you?
closely spaced contour lines indicate steep slopes, wider ones indicate gentle slopes
What does the spacing between contour lines tell?
closely spaced contour lines indicate steep slopes, wider ones indicate gentle slopes
Widely spaced contour lines indicate a?
Widely spaced contour lines indicate a gradual slope, while closely spaced lines indicate a steep slope.
On topographical map how do represent a steep slope?
Contour lines that are closely spaced
In a map closely spaced oval contour lines may indicate what?
They would indicate either a sudden increase or decrease in elevation, which could mean a hill, mountain, or depression in topography.
Do Equal points of elevation on a topographic map are connected by contour lines?
A contour lines connects points of equal elevation.
Do contour lines spaced closely together indicate a steep slope?
Yes; slope is the change in height over a specific distance horizontally, while contour lines represent change in height. Therefore, the closer together the lines are, the more the elevation changes in an area of the same length, and the greater the slope.
Do closely spaced contour line indicate a steep slope or gradual slope why?
Contour lines are used to indicate elevation, and are most commonly used on topographical maps. On a topographical map, each contour line indicates a particular elevation, the value of which is determined by a scale indicated on the map. Each contour line might, for example, indicate a rise of 20 feet. The closer the contour lines are to one another, the steeper the slope, since the rise in feet remains constant. Ultimately, as in the case of a nearly vertical cliff, the contour lines can become so closely packed together that they appear as a solid band.
