How do contour lines indicate a steep slope?
Contour lines show the elevation of the ground. 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.
Why contour lines are closer together on steep slopes?
When contour lines are closer together on a map, they indicate a steep slope. Think of contour lines as the distance between each incline. The closer together the inclines, the steeper the hill. On the other hand, the farther apart lines tend to indicate a depression in the landscape.
What do contour lines that are close together show?
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.
What is the contour pattern of steep slope?
The slope is always perpendicular to contour lines. The less separation between contour lines means a steeper slope and vice versa. When there are evenly spaced contours, the slope is uniform. At a stream junction, contour lines form an “M” or “W” shape. This can be interpreted as two “V-shaped contours intersecting.
What is a steep slope in geography?
A steep slope rises at a very sharp angle and is difficult to go up.
How do you tell if a slope is steep or gentle?
You can describe the slope, or steepness, of the ramp and stairs by considering horizontal and vertical movement along them. In conversation, you use words like “gradual” or “steep” to describe slope. Along a gradual slope, most of the movement is horizontal. Along a steep slope, the vertical movement is greater.
What is steep slope and gentle 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.
What is a concave slope?
A terrain feature that is rounded inward like the inside of a bowl, i.e. goes from more steep to less steep.
How are the contour lines on concave slope?
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.
How do you contour lines show steep and gentle slopes?
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.
What characteristic of contour lines indicates steep terrain?
Closely spaced contour lines 1. Closely spaced contour lines indicate a steep slope (Figure F-1). 2. Widely spaced contour lines indicate a gentle slope (Figure F-2).
What is a steep slope called?
An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations.
What is steep slope and example?
A steep slope rises at a very sharp angle and is difficult to go up.
What is the steepest slope?
The steepest slope is that of the line that is closest to being vertical. This could be a line that has positive slope OR negative slope…the steepest one should be determined by examining the ABSOLUTE VALUES of these four slopes.
What are steep slopes?
Steep slopes means any slope equal to or greater than 20 percent as measured over any minimum run of 10 feet. Steep slopes are determined based on contour intervals of two feet or less.
What is gentle and steep slope?
A steep slope refers to a sharp incline; a gentle slope refers 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 a steep slope look like on a topographic map?

What is a steep slope on a mountain?
A Steilhang (pl: Steilhänge) is a geoscientific term for a steep mountainside or hillside (or a part thereof), the average slope of which is greater than 1:2 or 30°.
What does a steeper slope indicate?
A steeper slope in a graph means that the rate of change is faster.

How does a contour map show areas of steep gradient?
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. 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.
How do you make a steep slope?
There are two ways to build a house on a sloped lot: using the “cut and fill” method, or making use of stilts. Cut and fill refers to the process of leveling out the ground for the foundation by adding soil, removing it, or both.
What is a steep line on a graph?
Slope describes the steepness of a line. The slope of any line remains constant along the line. The slope can also tell you information about the direction of the line on the coordinate plane. Slope can be calculated either by looking at the graph of a line or by using the coordinates of any two points on a line.

What is the steepness of a line?
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
What does steep line mean?
The steepness, incline, or grade of a line is measured by the absolute value of the slope. A slope with a greater absolute value indicates a steeper line. The direction of a line is either increasing, decreasing, horizontal or vertical.
What does a steeper line on your graph mean?
A steeper slope in a graph means that the rate of change is faster.
What is slope on contour map?
Measuring slopes on a contour map: – Measure the distance between the contour lines (at right angles to the lines themselves). – Slope = "rise over run", or vertical height increase over horizontal distance.
