How do you tell which way a stream flows on a topographic map?
Water always flows downhill perpendicular to the contour lines. As one proceeds upstream, successively higher and higher contour lines first parallel then cross the stream. This is because the floor of a river valley rises as you go upstream. Like-wise the valley slopes upward on each side of the stream.
How can you determine which way a river is flowing on a topographic map quizlet?
by using the V rule (general compass direction) which is when the contour lines create a v shape to indicate stream flow. The open side of the v shows the direction of the stream flow.
How do contour lines show stream direction?
How do contour lines show stream direction? Contour lines show stream direction with the V-shaped lines through which you see the streams and rivers run through on a topo map. Because water flows downhill, the V-shape always points in the opposite direction that the water is flowing. This is called the “Rule of V's”.
What direction is the stream flowing?
0:422:07Topos-Stream Flow – YouTubeYouTubeStart of suggested clipEnd of suggested clipWell the rule is very simple the V is always point upstream remember upstream means opposite whereMoreWell the rule is very simple the V is always point upstream remember upstream means opposite where the stream is flowing. So another way of saying it is that the stream flows out of the V's.
What does a topographic map show?
The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earth's surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level.
What do V shaped contour lines represent?
V-shaped contour lines indicate valleys, ravines, or gullies. Closely-spaced contour lines depict steep slopes. More widely- spaced contour lines indicate gradual slopes.

What determines the direction of river flow?
The direction of flow is determined mostly by the area's topography located between the headwater (origin) and mouth (destination). Also, rivers not only follow one direction; some turn and twist in several directions. It is important to note that a compass direction does not influence the flow of a river.

How do you know what direction a stream flows if there are no elevation numbers on the contour lines?
What are contour lines? how can you determine the direction a stream flows using contour lines? STREAMS ALWAYS FLOW IN THE OPPOSITE DIRECTION FROM THE WAY THE CONTOUR LINES BEND.
What happens when a contour line crosses a stream?
When contour lines cross a stream, they form a “V” that always points uphill. As a general rule, water flows downhill perpendicular to contour lines.
What do the lines on a topographic map represent?
A topographic map illustrates the topography, or the shape of the land, at the surface of the Earth. The topography is represented by contour lines, which are imaginary lines. Every point on a particular contour line is at the same elevation. These lines are generally relative to mean sea level.
What determines the direction a river flows quizlet?
divide- the high point or ridge that determines the direction that determines the direction that rivers flow.
How do you describe topography?
Topography is a measurement of elevation, and slope is the percent change in that elevation over a certain distance. Topography may be measured with lines that connect points representing the same elevation; these are called topographic contours.
What do each of the contour lines on a topographic map represent?
A topographic map illustrates the topography, or the shape of the land, at the surface of the Earth. The topography is represented by contour lines, which are imaginary lines. Every point on a particular contour line is at the same elevation. These lines are generally relative to mean sea level.

What determines the direction a river flows?
Gravity is the ultimate determining force in terms of water flow. Water will flow downhill from the highest point to the lowest point using the path of least resistance. Sometimes, that will make the water flow to the east, west, or north instead of south.
What is a high point or ridge that determines the direction that rivers flow?
define divide. divide– the high point or ridge that determines the direction that determines the direction that rivers flow. define headwaters. headwaters- source of rivers.
What would you see on a topographical map?
Topographic maps show contours, elevation, forest cover, marsh, pipelines, power transmission lines, buildings and various types of boundary lines such as international, provincial and administrative, and many others.
What directions do most rivers flow?
Rivers flow in one direction all over the world, and that direction is downhill. Across the central and eastern United States, it is rare for rivers to flow north because the slope of the land is toward the south and east.
Do all rivers flow the same direction?
Rivers flow in one direction all over the world, and that direction is downhill. Across the central and eastern United States, it is rare for rivers to flow north because the slope of the land is toward the south and east.
What determines the direction of a river?
The direction of flow is determined mostly by the area's topography located between the headwater (origin) and mouth (destination). Also, rivers not only follow one direction; some turn and twist in several directions. It is important to note that a compass direction does not influence the flow of a river.
What determines the path that the stream flows?
Topography plays a major role in determining a river's course. Water will always seek the path of least resistance. It will go around or under rather than up and over whenever possible.
What direction do most rivers flow?
Rivers flow in one direction all over the world, and that direction is downhill. Across the central and eastern United States, it is rare for rivers to flow north because the slope of the land is toward the south and east.
What determines the flow of water?
The flow of water from your faucet is determined by water pressure. The more water that is being forced through a pipe, the more pressure there will naturally be. Through any pipe size, higher water pressure will cause greater water flow.
Do all rivers flow in the same direction?
Rivers flow in one direction all over the world, and that direction is downhill. Across the central and eastern United States, it is rare for rivers to flow north because the slope of the land is toward the south and east.
What is water flow in a stream called?
Streamflow, or channel runoff, is the flow of water in streams and other channels, and is a major element of the water cycle. It is one component of the movement of water from the land to waterbodies, the other component being surface runoff.
What is the only river that flows backwards?
