What do contour lines that are uniformly spaced indicate quizlet?
Evenly spaced contour lines of different elevation represent a uniform shape.
What does it mean when contour lines are closely spaced together?
Contour lines that are relatively close together indicate a slope that is fairly steep. Contour lines that are further apart indicates a slope that is relatively flat.
What is uniform contour?
– Uniform slopes have uniformly spaced lines. – Along plane surfaces, contour lines are straight and parallel. – Contour lines are perpendicular to lines of steepest slopes. – For summits or depressions, contour lines most close upon themselves.
What do contour lines that are spaced close together indicate quizlet?
What do closely spaced contour lines indicate? They indicate a steep slope.
What can you say about the relationship between the spacing of contour lines and the steepness of the surface?
Closely spaced contour lines represent steep slopes, conversely, contour lines that are spaced far apart represent gentle slopes.
How do contour lines tell you the direction a stream flows?

When contour lines are closely spaced How is downhill indicated?
Closely spaced contour lines indicate a steep slope (Figure F-1). 2. Widely spaced contour lines indicate a gentle slope (Figure F-2).
How contour spacing indicates the steepness of a slope?
Spacing tells us about the slope. Given that the two images are from a map of the same scale, we can state that where the contours are closer together, the slope is steeper. Closer spacing of contours tells us that elevation is changing faster over distance, in other words, a steeper gradient.
What do the pattern and spacing between contour lines indicate?
Spacing tells us about the slope. Given that the two images are from a map of the same scale, we can state that where the contours are closer together, the slope is steeper. Closer spacing of contours tells us that elevation is changing faster over distance, in other words, a steeper gradient.
What does it mean when Isolines are spaced farther apart?
When isolines are close together – they show a rapid horizontal change. When isolines are far apart – they show a gradual horizontal change.
What do contour lines represent on a topographic map?
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 far apart are contour lines on a map?
A contour is a line drawn on a map that joins points of equal height above sea level. For 1:25 000 scale maps the interval between contours is usually 5 metres, although in mountainous regions it may be 10 metres.
How would contour lines be spaced on the slope of a hill?
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 contour lines help to distinguish between different types of slope?
Answer: This slope can be determined from the map by studying the contour lines—the closer the contour lines, the steeper the slope; the farther apart the contour lines, the gentler the slope. Totally flat ground has no contour lines.
When contour lines are closely spaced at the bottom of the slope and spaced further apart on the upper part of the slope then we have a?
Contour lines that are widely spaced at the top of the slope and closely spaced at the bottom of the slope depict a convex slope. Contour lines that are closely spaced at the top of the slope and widely spaced at the bottom depict a concave slope. 5.
When the contour lines having the same contour interval are farther apart it shows a?
Closely spaced contour lines represent steep slopes, conversely, contour lines that are spaced far apart represent gentle slopes. 3.
What type of terrain should one expect if contour lines are closely spaced widely spaced?
Closely spaced contour lines indicate steep slopes. Widely spaced contour lines indicate gentle slopes or relatively flat areas. A contour line that forms a closed loop with no other contour lines inside indicates a hilltop.
How do contour lines indicate a stream?
The rule of V and U-shaped valleys All rivers flow downhill from higher to lower elevations, perpendicular to the contour line above them. 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.
What does contour lines mean in geography?
Contour lines are the faint red-brown lines drawn on a map connecting points of equal elevation above sea level, meaning if you physically followed a contour line, the elevation (height of the land) would remain the same. Contour lines show elevation and the shape of the terrain.
What is uniform slope?
A slope, or part of slope, which has no change in angle. On a map the contour lines will be spaced evenly. If they are evenly spaced close together then the slope is uniformly steep. If evenly spaced some distance apart the slope is uniformly gentle.
When the contour lines having the same contour intervals are farther apart it shows a?
Closely spaced contour lines represent steep slopes, conversely, contour lines that are spaced far apart represent gentle slopes. 3.
When contour lines are spaced closer together that would indicate a flatter surface?
3.4. 55). In hilly areas, the contour lines are close together while they are wider apart on flat slopes. The closer the contour lines, the steeper the slope. The wider the contour lines, the flatter the slopes.
When the contours are closely spaced and in a series represents?
Closely spaced contours represent steep slopes while widely spaced contours represent gentle slope. When two or more contour lines merge with each other, they represent features of vertical slopes such as cliffs or waterfalls.
Why do different contour lines have different shapes and spacing?
Spacing tells us about the slope. Given that the two images are from a map of the same scale, we can state that where the contours are closer together, the slope is steeper. Closer spacing of contours tells us that elevation is changing faster over distance, in other words, a steeper gradient.
What are contour lines on a topographic map?
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.
Which type of slope is shown by closely spaced contour lines?
Closely spaced contour lines indicate steep slopes. Widely spaced contour lines indicate gentle slopes or relatively flat areas.
What type of slope is there when the contours are far apart?
3.4. 55). In hilly areas, the contour lines are close together while they are wider apart on flat slopes. The closer the contour lines, the steeper the slope. The wider the contour lines, the flatter the slopes.
What are the features of contour lines?
Characteristics of Contours
- Must close on themselves, on or off the map.
- Perpendicular to the direction of max. …
- Slope between them is assumed uniform.
- The distance between them indicates the steepness of the slope, gentle or steep.
- Irregular signify rough, smooth signify gradual slopes.
What is the function of contour lines on a map?
Earth's surface has many different kinds of landforms that vary widely in height and elevation. Contour maps show the elevations of these surface features, which allows you to look at a two-dimensional map to visualize the Earth in three dimensions.
What is the role of spacing in a topographical map explain with the help of two examples?
These lines are evenly spaced apart. We call this spacing the contour interval. For example, if your map uses a 10-foot contour interval, you will see contour lines for every 10 feet (3 meters) of elevation — lines at 0, 10, 20, 30, 40 and so on. Different maps use different intervals, depending on the topography.
