Do contour lines always point upstream?
Relief = Maximum elevation – Minimum elevation
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.
Do contour lines point uphill?
Rule 1 – every point of a contour line has the same elevation. Rule 2 – contour lines separate uphill from downhill. Rule 3 – contour lines do not touch or cross each other except at a cliff.
Which way does water flow on contour lines?
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.
What direction do contour lines bend along a river upstream or downstream?

How do contour maps work?
Put simply, contour lines mark points of equal elevation on a map. If you trace the length of a line with your finger, each point you touch is the same height above sea level. If you were to walk the path of a contour line in real life, you would remain at the same elevation the whole hike, never traveling up or down.
How do streams look on a contour map?

Why do contour lines v upstream?
The rule of V and U-shaped valleys
All rivers flow downhill from higher to the lower elevations, perpendicular to the contour line above it. As a rule of thumb, the V-shaped contour is pointing upstream (the opposite direction from the flow of a stream or river). The “V” shape contours indicate streams and drainage.
Do steep contour lines indicate water?
The area of the map above boxed in orange shows an area that has a fairly steep slope, while the area boxed in purple is a relatively flat area. Contour lines on the map also show how water will travel across the land. Contours that form a V can you tell which direction water will flow.
How do you identify a stream on a contour map?
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.

Can contour lines ever overlap?
Contour lines also never touch or overlap, unless certain rare instances occur, such as if there is a vertical or overhanging cliff. In the case of a vertical cliff, the contour lines will appear to merge.
What are contour lines on a topographic map?
A contour line is a line drawn on a topographic map to indicate ground elevation or depression. A contour interval is the vertical distance or difference in elevation between contour lines.
Can contour lines touch each other?
Contour lines never cross.
They may come very close to each other (e.g. along a cliff), but by definition they may never cross each other. * This is because one location on the surface of Earth cannot be at two different elevations!
How are contour lines drawn on maps?
Contour lines are the main characteristics of a map. Contour lines are lines drawn on a map with equal elevation points, so elevation would be constant if you followed the contour line physically. The elevation and terrain shape of the contour lines shows.
When contours cross a stream on a map the apex point of the V points in the downstream direction?
when contour lines cross a river or stream, they bend to form a “V”. The “V” points upstream or the river flows out of the mouth (wide part) of the “V”.
How do you read elevation contour lines?
You can figure out the elevation of any point by finding the nearest labeled line, counting the number of lines above or below it, multiplying by the contour interval, and adding or subtracting the result from the nearest marked contour line. The more closely spaced the contour lines, the steeper the slope.
What are the types of contour lines?
- Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. …
- Intermediate lines are the thinner, more common, lines between the index lines.
Where are contour maps useful?
Contour maps help us to understand the characteristics of the landforms. These maps are of immense use to mountaineers, trekkers, soldiers, defense officers, etc. These maps prove to be of great use in the planning for a region too.
What is the shape of contour lines?
At a stream junction, contour lines form a “M” or “W” shape. This can be interpreted as two “V-shaped contours intersecting.
What is the difference between a contour map and a topographic map?
Bathymetric maps show depths of landforms below sea level. Topographic elevations and bathymetric depths are often shown on maps with contour lines. A contour line represents a corresponding imaginary line on the surface of the land or bottom of the ocean that has the same elevation or depth along its entire length.
How do you read a 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 do you read a groundwater contour map?

How do you determine stream order?
First- through third-order streams are called headwater streams. Over 80% of the total length of Earth’s waterways are headwater streams. Streams classified as fourth- through sixth-order are considered medium streams. A stream that is seventh-order or larger constitutes a river.
How can you identify stream or river channels based on the shape of contour lines Group answer choices?
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 contour lines show steep and gentle slopes?
When contour lines are closer to each other, the slope is steep. When contour lines are further apart from each other, the slope is gentle.
How do topographic maps represent elevation and relief?
it shows relief by using different colors for different elevations. Sometimes they show it using contour lines.
Why are topographic maps useful?
Topographic maps give the user the ability to view a three-dimensional landscape on a two-dimensional map. One who is able to read a topo map can identify the elevation and location of valleys, peaks, ridges, and other land features.
How do you find the contour interval on a topographic map?
https://www.youtube.com/watch?v=XkBaqXQJh5c
What does a steep slope look like on a topographic map?
Contour lines that are close together indicate a steep slope. This is because the elevation changes quickly in a small area. Contour lines that seem to touch indicate a very steep slope, like a cliff. When contour lines are spaced far apart, the slope is gentle.
Why are geographers slopes important?
1 Definition. A slope is the rise or fall of the land surface. It is important for the farmer or irrigator to identify the slopes on the land. A slope is easy to recognize in a hilly area.
Which way does the stream flow?

Which data are shown on topographic maps?
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 is a contour profile?
A contour is a line on a map that connects adjacent points of equal elevation. CONTOUR INTERVAL (C.I.) – A contour interval is the vertical distance or difference in elevation between contour lines. If the numbers associated with specific contour lines are increasing, the elevation of the terrain is also increasing.
Can contours split?
Contour lines never split or branch.
Why do two contours never intersect each other?
Two contours never intersect each other because each line represents a separate elevation, and we can’t have two different elevations at the same point.
When can two contours cross each other?
Two contour lines, can cross each other in case of Overhanging cliff. Two contour lines cannot unite together except vertical cliff.
Which statement is not true about contour lines?
Answer: C – The statement “Contour lines are parallel to the direction of maximum slope” is NOT true. Contour lines are perpendicular to the direction of maximum slope. The contour interval for contour lines is the constant vertical distance between adjacent contour lines.
Why don t all topographic maps have the same contour interval?
Each contour line represents a different elevation, and you can’t have two different elevations at the same point. An example would be how 500 meters above sea level will never be equivalent to 1000 meters above sea level.
What are the 5 Rules of topographic maps?
- Contour Lines Never Cross. …
- Measuring Steepness. …
- Stream Flow Direction. …
- Contours Close. …
- Concentric Circles. …
- Elevation Between Lines.
How do you draw a contour graph?

When a contour crosses a stream it needs to make a V shape pointing upstream?
Rule # 4- Contour lines that cross a valley or stream are V-shaped. Contour lines “point” upstream when they cross a river or stream. Look at the Mill River in the map to the right. The V points toward the area of higher elevation.
What does it mean if contours are closely spaced?
Contour intervals reveal how much vertical distance there is between each contour line—closely spaced contour lines indicate very steep slopes. Contour lines that are sharply tapered indicate an uphill direction. Rounded contour lines typically indicate a downhill direction (gradual slope).
How do you use topographic maps?

What is a contour graph?
A contour diagram is simply a graph on the xy-plane that shows curves of equal height for a two-variable function z = f(x, y).
What are contour lines ks2?
These are lines that show high and low areas of land. The contour lines join up areas of the same height, and when they are close together it means the hill or mountain is steep.
What are the 3 types of contour drawing?
- Blind Contour. ‘Blind contour drawing’ is when contour drawing is done without looking at the paper AT ALL. …
- Continuous Line Contour. …
- Modified Contour. …
- cross-contour. …

What are contour lines art?
A contour line defines the outline of a form, as well as interior structure, without the use of shading. A fundamental basis of drawing, contour lines are usually the first technique children adopt to draw people, houses, and trees.
How do you find contour lines?
You can find the contour interval in the map key, usually located underneath the scale of the map at the bottom center.
How do contours work?
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. Where contour lines are wide apart, elevation is changing slowly, indicating a gentle slope.
What kind of map shows elevation differences and topography?
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.
How do you describe a contour map?
A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes. The contour interval of a contour map is the difference in elevation between successive contour lines.
What are contour landforms?
CONTOURS. Contours are imaginary lines joining places having the same elevation above mean sea level. A map showing the landform of an area by contours is called a contour map. The method of showing relief features through contour is very useful and versatile.
What is contour mapping in geography?
contour mapping, the delineation of any property in map form by constructing lines of equal values of that property from available data points.
