Why do the lines bend upward on a contour map when indicating a stream?

The lines bend upward to show that the stream is running the opposite way. (For example, if the lines are pointing north, the stream is running south)
**Contour lines bend toward the source when they go over a river/stream.

∙ 14y agoA stream valley is discernable on a topographic map by lines of equal elevation that run parallel to each other where the stream valley is on level terrain and converge in a "v" shape where the stream valley is on a slope. Parallel equal elevation lines may be nested where the difference in elevation between the edges and the center of the valley is great enough. A single countour line may run along the middle of the stream valley where it is on level terrain, but not always.

Whether they bend or not depends on the actual course of the valley.

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.
To contour lines depicting a valley or draw are you or v-shaped what does the closed end of the contour line point to?
The point of the V is probably where there is a stream, river or wash.

What is the definition of hachured contour lines?
Hachured contour lines are contour lines with ticks pointing downslope that indicate a depression on a topographic map.
What do the numbers on index contour lines indicate?
The numbers of contour lines indicate altitude or elevation along that line.
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.
How do contour lines show stream direction?
indicated with different kind of contour numbers , which are showed in brown curved lines
Do contour lines crossings a small stream point up-stream or downstream?
Upstream
How do you know if your going uphill or downhill by looking at a contour map?
contour lines all ways point up hill or up stream
How must contour lines bend to indicate a stream valley?
contour lines bend in a V shape pointing uphill because it flows the other direction
How do contour lines bend when crossing a stream?
Because we know that water cannot flow uphill, the flow must go from higher contours to lower ones.
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 is the type of map that shows land in three dimension using contour lines indicating elevation?
Topographical Map
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 would you show an island in the ocean with the elevation of 80 feet if the contour interval is 10 feet?
With eight contour lines that follow the upward elevations in increments of 10 feet.
To contour lines depicting a valley or draw are you or v-shaped what does the closed end of the contour line point to?
The point of the V is probably where there is a stream, river or wash.
