What are the factors effecting contour intervals?
If the contour interval is not given, find two reference (labeled) contour lines and find the number of lines between them, excluding the reference lines themselves. Then the interval can be found using the following formula: |(Difference between elevation of reference lines)| /(Number of contour lines between reference lines +1) = Contour interval For example, if you find two reference lines labeled 150m and 250m and there is one contour line between them, then |150m-250m|/(1+1)=100m/2=50m The contour interval of that map is 50 meters.
How can you determine whether the contours on a topographic map show a gradual slope?
If the topographic lines are closer together it means that it has a steeper slope grade, if they are farther apart, it means that they have a more relaxed slope grade. There is usually a scale on the map that can tell you in exact measurements of the slope.
On a topographic map contour lines that are close together indicate a?
A very steep regionClosely spaced contour lines indicate a very steep slope.Conversely, widely spaced lines indicate areas that are nearly flat.-Leftover.Tech
What kind of map that uses shading and elevation lines?
That would be a topographical map. It uses contour lines (usually 100 or 50 ft. incraments) to show elevation above or below sea level. They're usually black & white and can be found wherever you can find maps.
What is a tipografic map?
A topographic map is a type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines in modern mapping, but historically using a variety of methods. Traditional definitions require a topographic map to show both natural and man-made features.

How are river valleys represented on a topographic map?
Usually by contour lines, with the river shown in blue.

What is a index contour?
A thicker line that has numbers written on it showing the rising or decreasing elevation on a topographic map By Ash Every fifth contour line on a topographic map, usually thicker, used to label elevation.
What is the elevation difference between one contour line and the next?
The height between contours is usually stated in the map's legend. For instance, on an Ordnance Survey (UK) 1:50 000 Landranger Series, contours are at 10 metres vertical interval.
What do theTopographic maps show?
Topographic maps display both natural and manmade features in a specific area. Topographic maps usually also feature various contour lines to help with segregating the map into blocks for easier identification of specific locations or features.

Are contour sketches always used in maps?
No, usually only on topographic maps. Other maps (e.g. street map, road map, voting districts map) have no use for them.
What is the elevation change between two adjacent lines on a map?
Those lines representing elevation on a map are called contour lines. The difference in elevation between two of these lines is called the contour interval. Different maps use different contour intervals based on the scale of the map, or in other words, the size of the contour interval is based on how zoomed in and detailed the map is. Sometimes a map will have darker and thicker contour intervals. This is called the Index Contour Interval. Index contour intervals appear less frequently and represent a larger elevation change. It helps you figure out the amount of a large elevation difference faster because usually they are multiples of 100 or 1000, making them easier to add up.

Contour lines on a topographic map indicate?
Usually the altitude above sea level. Close lines indicate a steep slope while spread out lines show flatter terrain.
How would a topographic map help plan hiking routes that can be easy for new hikers?
A topographic map shows elevations, and large differences in elevation close together indicate steep slopes, which hikers may want to avoid. A path with the smallest differences in elevation will usually be a flatter, more easily-walked path.
