How do contour lines show the direction of stream flow?
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.
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 do lines on a contour map indicate?
Contour lines connect points that share the same elevation: Where they're close together (they never intersect), elevation is changing rapidly in short distance and the terrain is steep.
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.
Which direction is the water flowing?
Actually, water flows downhill in any direction, because it always wants to get to the lowest level as quickly as possible due to the gravitational pull. Compass direction doesn't matter.
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.
How do you read a contour plot?
How to interpret contour plot?
- Contour plots can indicate peaks or valleys within the range of X and Y at the center of concentric shapes.
- If the contour lines are spaced close to each other, then the values change rapidly while if the contour lines are spaced far apart then the z values change more slower.
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.
When contour lines cross over a flowing body of water such as a river the contour lines will quizlet?
Terms in this set (25) Contour lines bend upstream and form a "V" when crossing a stream, river, or creek.
What determines the direction of water movement into or out of cells?
The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity. Tonicity is a bit different from osmolarity because it takes into account both relative solute concentrations and the cell membrane's permeability to those solutes.
How do you calculate flow direction on a grid?

How do you determine the left and right banks of a river?
The right bank or side is always on the right side of the direction in which the water is flowing ie facing downstream, and the left bank is always the left hand side facing downsteam.
How do you know which way is downstream?
Downstream means towards where the flow ends, at the opposite end of the waterway from the source. If you are boating from Kingston to Toronto, for example, you are heading upstream. If you are going from Kingston to Cornwall, you are travelling downstream.

What do contour lines on a topographic map connect?
Contour lines connect points that share the same elevation: Where they're close together (they never intersect), elevation is changing rapidly in short distance and the terrain is steep.
Which direction do contour lines bend when they cross a stream?
upstream Contour lines trend up valleys, cross streams, and return down the valleys on the opposite side, thus forming a V (or a U) that points upstream: A contour line bends upstream when crossing a stream and forms a V whose apex or point always points upstream.
When a contour lines crosses a river it bends to form a point or V?
Rivers always flow from higher elevations to lower elevations, therefore, look at the value of the contour lines to determine direction. When a contour line crosses a river, the line bends to form a "V" that points upstream. Rivers flow from upstream to downstream.
How do you determine the direction of net flow of water?
The direction of net solvent flow is always from the side with the lower concentration of solute to the side with the higher concentration. Osmosis can be demonstrated using a U-tube like the one shown in Figure 13.7.
What is the direction of water flow?
Actually, water flows downhill in any direction, because it always wants to get to the lowest level as quickly as possible due to the gravitational pull. Compass direction doesn't matter.
What is flow direction map?
Flow direction means the direction the stream flows in each cell. Please see the figure below the direction coding; it is called eight-direction flow direction coding.
Which method is used to find the flow direction from a digital elevation map?
In this case, a computer calculates the slope (elevation difference divided by the distance) in each of the directions and determines the flow direction as the steepest one. This simple algorithm is called the D8 method.
How do you find the left bank of a river?
A "left-bank tributary" or "right-bank tributary" indicates the side of the river a tributary enters. When identifying a left-bank or right-bank tributary, a geographer looks downstream (the direction the river is flowing).
Which side is river right?
River right always refers to the right side of a river looking downstream.
How do you determine upstream and downstream?
To help you remember which way is upstream on a river, if water comes from, for example, the mountains and flows in a river to the sea, water near the mountains (or source) is upstream, and water nearer the sea is downstream.
What is flow direction?
Flow direction means the direction the stream flows in each cell.
How do you read a contour graph?
Use contour plots to display the relationship between two independent variables and a dependent variable. The graph shows values of the Z variable for combinations of the X and Y variables. The X and Y values are displayed along the X and Y-axes, while contour lines and bands represent the Z value.

How do contour plots work?
A contour plot is a graphical technique for representing a 3-dimensional surface by plotting constant z slices, called contours, on a 2-dimensional format. That is, given a value for z, lines are drawn for connecting the (x,y) coordinates where that z value occurs.
