Contour lines need to bend uphill to indicate a stream valley. It's like nature's way of saying, "Hey, there's a river flowing through here, pay attention!" So, if you see those contour lines curving uphill, you better believe there's some water action happening nearby.
V-shaped contour lines indicate a valley or a depression when the point is uphill. The V-shape of the contour lines indicates that the elevation is decreasing in that direction, forming a valley or depression.
Contour lines will bend and point upstream to form a "V" shape when crossing a stream valley on a topographic map. The V-shape indicates the direction of the stream flow and shows the gradual slope of the valley.
V-shaped contour lines pointing uphill indicate a steep slope or ridge. The closer the contour lines are together, the steeper the slope.
When V-shaped contour lines point downhill, they indicate a valley or depression on the map. When they point uphill, they indicate a ridge or hill on the map.
It means a small difference in elevation, let's say, for an example, a river.
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.
The point of the V is probably where there is a stream, river or wash.
Contour lines that are far apart indicate gradual slopes, while contour lines that are close together indicate steep slopes.
On a topographic map, contour lines that are closer together indicate a steeper slope.
The numbers of contour lines indicate altitude or elevation along that line.
A valley or a ravine is typically represented by V-shaped contour lines on a topographic map. These lines indicate a steep-sided depression or low-lying area between higher elevations.
- 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.
