How are the gentle and steep slopes shown on the topographical map?

A contour line is drawn to show places of equal heights. Contour lines and their shapes represent the height and slope or gradient of the landform. Closely spaced contours represent steep slopes while widely spaced contours represent gentle slope.

How will you identify a gentle and steep 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 are steep slopes shown on the map?

Interpreting Contour Maps. Closely-spaced contour lines indicate a steep slope, because the elevation changes quickly in a small area. Contour lines that seem to touch indicate a very steep rise, like a cliff or canyon wall. Broadly spaced contour lines indicate a shallow slope.

What is gentle slope in geography?

A gentle slope or curve is not steep or severe.

What is steep slope?

Steep slopes are legally defined as hillsides having a 15 foot, or greater, vertical rise over 100 feet of horizontal run, or 15\% slope (Figure 1). They are often undesirable ar- eas for development due to the difficulty of building on steep grades.

What does a gentle slope look like?

Gentle: Contour lines showing a uniform, gentle slope will be evenly spaced and wide apart. Easy walking. Steep: Contour lines showing a uniform, steep slope on a map will be evenly spaced, but close together.

What is slope on a topographic map?

Slope Calculation from Contour Lines in a Topographic Map. Slope is the measure of steepness or the degree of inclination of a feature relative to the horizontal plane. Gradient, grade, incline and pitch are used interchangably with slope. The slope is obtained by dividing the rise over run.

What is steep and gentle?

In gentle slopes, the change 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 gentle slope of a mountain?

A cuesta (from Spanish cuesta “slope”) is a hill or ridge with a gentle slope on one side, and a steep slope on the other. In geology the term is more specifically applied to a ridge where a harder sedimentary rock overlies a softer layer, the whole being tilted somewhat from the horizontal.

What is steep slope and gentle 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. A 6\% slope means that the road elevation changes 6 feet for every 100 feet of horizontal distance (Figure 1.3).
