Do closely spaced contours indicate a steep slope?
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. Contour lines form “V” shapes in streams.
What indicates a steep slope?
A steep slope refers to a sharp incline; a gentle slope to a slight incline. The steep, forested slopes in Figure 1.1 contrast with the gentler slope of the river’s path as it flows between them.
What does closely spaced contour lines indicate?
Closely spaced contour lines indicate a steep slope (Figure F-1). 2. Widely spaced contour lines indicate a gentle slope (Figure F-2). 3. Evenly spaced contour lines indicate a uniform slope (Figure F-2), while irregular spacing indicates an irregular slope (Figure F-1).
What does the closely and sparsely spaced contours depict about the slope?
Evenly spaced contour lines indicate a uniform slope. 5. Closely spaced contour lines show a steep slope. 6.
What do closely spaced contour lines indicate on a topographic map?
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.
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.
When contour lines are closely spaced at the bottom of the slope and spaced further apart on the upper part of the slope?
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. Four types of slopes that concern bushwalkers are gentle, steep, concave, and convex.
What is a gentle gradual slope?
In gentle slopes, the change of elevation is gradual. Normally about 1:25 gradient of elevation is gradual. Steep slope suddenly slopes up or down. The contours are placed wide apart in gentle slope. For steep slopes, the contours are drawn close to one another.
How do contour lines determine elevation?
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.
How do you read the difference between a cliff and a gradual slope?
is that cliff is a vertical (or nearly vertical) rock face or cliff can be (music) while slope is an area of ground that tends evenly upward or downward.
What do contour lines that are uniformly spaced indicate quizlet?
Evenly spaced contour lines of different elevation represent a uniform shape.
How do you tell if contour lines are going up or down?
Remember contour numbering reads up hill – in other words the top of the number is uphill and the bottom is downhill. Also remember the closer contour lines are together, the steeper the slope.

Which of the following would indicate a gentle slope?
Widely separated contour lines indicate a gentle slope. Contour lines that are very close together indicate a steep slope. The figure above illustrates various topographic features. (b) Notice how a mountain saddle, a ridge, a stream, a steep area, and a flat area are shown with contour lines.
How is gentle slope indicated?
A contour line is drawn to show places of equal heights. Closely spaced contours represent steep slopes while widely spaced contours represent gentle slope.
What is the difference between a gentle and a steep slope?
Answer: A gentle slope has a low slope angle and is characterized by contour lines spread widely apart whereas a steep slope has a slope angle and is characterized by closely spread contour lines.
How the steepness of a terrain will impact the appearance of contour lines on a topographic map?
The spacing of contour lines shows the slope of the land.
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.
What is difference between slope and steep?
As adjectives the difference between slope and steep
is that slope is (obsolete) sloping while steep is of a near-vertical gradient; of a slope, surface, curve, etc that proceeds upward at an angle near vertical.
How do you determine elevation?
An easy-to-remember equation for finding change in elevation as a decimal is “rise over run,” meaning the rise (the change in vertical distance) divided by the run (the change in horizontal distance). As an example, let’s say the rise is 2 and the run is 6. So, you’d take 2 over 6 (or 2/6) to get .
What is the elevation 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.
What is the relationship between hill slope and contour line spacing?
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.
How are the contour lines arranged in an area with a very gradual slope?
In the case of a gradual slope, the contour lines are far apart. In the case of a steep slope, the contour lines are closer to one another.
What is considered a moderate slope?
Moderate slopes: 10 – 15 % gradient. D. Steep. Steep slopes: 16 – 30 % gradient.
How do contour lines show different slopes of land?
Contour lines show: Elevation of land: The height of a contour is indicated by figures inserted in a break in the line. Steepness of its slope: When the contours are very close, they represent steep slopes. When they are farther apart, they represent gradually increasing slopes.
Do contour lines always close an irregular circle?
Contour lines always close to form an irregular circle. But sometimes part of a contour line extends beyond the mapped area so that you cannot see the entire circle formed. The elevation between any two adjacent contour lines of different elevation on a topographic map is the contour interval.
Which side of the island has a steep slope a gentle slope How do you know?

What are the 5 Rules of contour lines?
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. Rule 4 – every 5th contour line is darker in color.
What is the difference between convex and concave slopes?
Explanation: The concave slope is represented by the closely spaced contour in the upper locations and gradually become widely spaced in the lower areas. – Convex slope is a geographical feature with inconstant slopes. The upper part is less steep than the lower part.
Can contour lines merge?
For closed contour type objects, the contours can either be joined by a closely-spaced pair of connecting lines or concatenated end to end. The connecting lines will be up to two pixels apart, or closer together if the spacing between contour points is less than 2 pixels around the points chosen for joining.
What is a side view of a particular area?
A profile is a side view of a particular area.
Which of the following can you use to tell you the steepness slope of the terrain?
Contour lines indicate the steepness of terrain.
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.
How do you find slope from vertical distance?
When hand calculating the vertical distance between points, this difference needs to be taken into consideration. Because the total station gives a true slope distance, the vertical difference is simply V = s * sin α (see figure below).
How do you calculate steepness?
Slope percentage is calculated in much the same way as the gradient. Convert the rise and run to the same units and then divide the rise by the run. Multiply this number by 100 and you have the percentage slope. For instance, 3″ rise divided by 36″ run = .
How do you find the slope between two altitudes?
To calculate percent slope, divide the difference between the elevations of two points by the distance between them, then multiply the quotient by 100. The difference in elevation between points is called the rise. The distance between the points is called the run. Thus, percent slope equals (rise / run) x 100.
When the lines get closer together the slope?
The closer they are together, the steeper the slope. If the lines are far apart, it means that the elevation change of 10 feet happens over a longer linear distance. This is a gentle slope, and would be easier and safer to walk.
When contours are widely spaced they depict?
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.
