How do contour lines show stream direction?
indicated with different kind of contour numbers , which are showed in brown curved lines
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.
What are the main topographic map rules?
contour lines can never cross. The closer the contour lines are, the steeper the land gets. If you move from one line to another, the elevation becomes different.
What do the lines on a contour map tell us?
The numbers on contour lines show the different elevations. Lets say one contour line says it has 1450 elevation. That means it is on the highest peak. When you see other numbers, that is just the elevation

Why can't two contour lines overlap?
One contour can not cross another because a contour is one exact elevation; if it crossed another contour it would show that it is higher than the second contour on one side, but lower on the other side.
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.
What are one dimensional drawings?
Straight lines.
How do contour lines show stream direction?

What is the definition of a contour line?
- Contour lines never cross. All lines on a contour line represent one elevation.- The spacing of contour lines depends on slope characteristics. Contour lines that are close together show a steep slope. Contour lines that are far apart show a gentle slope.- Contour lines that cross a valley or a stream are V shaped. The C points toward the area of the highest elevation. If a stream or river flows through the valley, the V points upstream.-The tops of the hills, mountains, and depressions are shown by closed circles. Depressions are marked with short, straight lines inside the circle that point down slope to the depression.
Why is it unlikely that two contour lines will cross?
Contour lines never cross because the elevations can't be two different numbers in one spot.
Why can't contour lines cross merge or split?
Contour lines are imaginary lines that join points of equal height. Therefore, say, a 300 metre height contour line can never meet a 400 metre height one.
What is the distance between Contour lines?
It is inversely proportional to the gradient: the steeper the slope the closer the contour lines until there comes a point where the ground is so steep the lines merge into one.
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.
