How much do contour lines show stream direction?

Water flows downhill. Contour lines show the slope of the landscape, and the direction a stream must flow.


What are three methods that hep you determine the direction a stream is flowing on a topographic map?

Look for contour lines that indicate the flow of water downhill. Check for small lines perpendicular to the stream that show the direction of the current. Identify the shape of the stream's valley, as valleys typically point in the direction of the stream flow.


How do you know what direction a stream goes on a contour map?

you can determine the direction a stream flows on a contour map by seeing which way the contour lines bend.


How do contour lines show hills and deppresions?

Contour lines that are close together indicate steep terrain, such as hills or mountains. When contour lines form closed loops with smaller lines inside, this indicates a depression or valley. The direction the contour lines bend can also show the shape of the land, with convex lines indicating hills and concave lines indicating valleys.


How can you find the direction a stream flows on a topographic map?

A contour map shows lines which connect areas equal in height. These lines are called contours and should be labelled to show the height that each contour represents. A stream flows downhill, this is due to gravity. Thus, to determine which way a stream flows, find contours, at least two, that intersect the path of the stream, then look at the heights these contours represents(their labels). The stream will flow from the contour labelled with the higher number towards the contour labelled with the lower number. PS. sometimes not all the contours are numbered, but only say every fith contour is numbered, then you can assume that all contours are equally incremented i.e. the height difference from one contour to the next stays equal.


What are the contour line rules?

- 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.


What contour lines show on a topographic map?

Contour lines show levels of elevation, where there are hills and valleys on a map


What do elevation maps use to show elevation?

Maps can show elevation with contour lines


How do contour lines show elevation?

The darker contour lines on map are called index contour lines. Numbers that indicate elevations are often written on these lines.
